Fractal Audio AX8.

Glad it showed up and that your initial feelings are so positive. I have a hunch that if more people tried these, their experiences would track similarly to yours. If you don't mind, I'll go section by section through your post and give my thoughts as well.

So it's here! The amp models are indeed spectacularly good, and the speaker models are very realistic. The computer based editing app is pretty much self-explanatory, once you get started.

The first thing I did is zero-out a bunch of presets. It's easy to do. For once, an editing app that understands me!
Yeah - either zero out some of the factory ones, or use the higher banks which are empty. I'm a little anal about my set, so I zeroed out the first two banks and am using those slots for my sounds. Those were guitar presets anyway, and if I want the factory ones, it's SUPER easy to restore them. AX8-Edit follows Axe-Edit (which is for the flagship Axe-Fx II). Coming from Axe-Fx's (Which I still own), I was instantly familiar with it. It's gone through a ton of iterations over the years, and I agree, that it is very simple to get going with it. It can also be easy to get deep in the advanced parameters and tweak things.

The speaker models are so realistic that they have the same problem as real speakers: you want the flavor, buy you don't always want that to be 100% of your tone. I set up a simple bypass blend, and with some filtering was able to blend together some quite amazing tones. The studio comp is good but it ain't no distressor. It feels like he's using actual RT-60 decay times instead of the fudged attack/release numbers on some comps, so I have to use longer times for attack/release than on other comps, which is IMO the right way to do it. But surprising.
I agree that the cab IRs are good, and I'd say over about the past year or so they have really come alive. More people are starting to throw their hat in on how to get IRs, and Fractal has learned a lot by doing and working with 3rd parties as well. Cab Pack 1 is free - go audition it and compare it to the ones that are in the unit from factory. You'll hear some of the progression.

On the compressors - each uses a different algorithm! Make sure to play with them all. I like using Studio, but when I need the CPU, I'll switch to Pedal 2. I'm not a fan of Pedal 1, but it certainly has its uses. Cliff and his dev team do stick to more standards such as RT-60, instead of more common systems. It can lead to a learning curve, but for me, just makes way more sense.
Also, keep in mind that the Amp block has a simple compressor available on output - "OUT COMP" is the name, if I recall correctly.

The front panel bass/mid/treble controls appear to be hard-wired to the amp model, so when you set up a blend, you lose the ability to control tone on stage. There may be a way to remap these, but I haven't found it yet. I'm thinking that it might be better to pick up the "clean blend" post-amp, as if it were speaker DI, roll off the high end, etc. This would retain tone controls and overdrive characteristics, while allowing me to tone down the overly honky characteristic of real bass cabs.
I believe that is true. You can also use the PEQ and EQ blocks post amp to do further EQ changes. A number of my presets have a PEQ at the end of the chain that I can toggle on/off. All three of my signal paths merge into that PEQ block and then go to OUT 1.

Having some difficulty understanding the gain structure. Apparently the amp block is *supposed* to add like 16-20dB of level, which makes a clean blend difficult. Why wouldn't it be unity gain internally, regardless of the output levels? But apparently you have options, tons of headroom, and a low noise floor, so I'm not really worried about it.
The Amp acts like a real amplifier :). You can use the OUTPUT LEVEL knob to control this, which is independent of the input and volume levels (and has no impact on tone or processing of that Amp block). On my blends, I tend to have an EQ block or a drive block on the non-Amp'd channel, which helps me balance things. You can also use the filter block, too. Like you said, there are a lot of options available. Experiment and find which you like and works best for you.

Haven't really had time to play with the effects yet--they seem great but the more weird-o bass player pedals seem to be missing. But then I'll bet I can build some strange stuff with the LFO, envelopes, overdrives and filters modular style. I didn't realize I was also getting a primitive modular synth in the deal... if it also had CV out you could do some crazy things with the FX loop. A bassballs is just a fuzz with an envelope following bandpass filter blended with clean, right? :)
Yeah, the "weird" and exotic effects aren't there. It's likely the bass specific ones won't be, at least not for a long time. I'm hoping that as more bass players come on board and voice our opinion on the lack of these options (on the Fractal forum, so Cliff and the other devs see it), that we can maybe someday get these in there. I like how you think, though - it is similar to me. You can do things here that aren't easy or practical to do with traditional setups. Play, tweak and have fun :). Having that good understanding of how "our" pedals work, definitely helps.

With that said, I haven't found an FX block that is unusable on bass other than the Synth block (which has a hard time tracking under the 12th fret). Everything else works fine, but does take more time to tweak for bass use than guitar.

Anyway, my first impression is that you can drop an amp and speaker into blocks, hook them to the input and output, and have a gig-able setup that basically sounds real. GREAT sounding piece of gear.
Absolutely can. While expensive to use just as that setup, it gives you so many options even if you just line up 4 presets with different amps and cabs. Add in a couple of FX for flavor and you're well beyond anything you can easily do otherwise, and for less money.

Already I have some negative observations:

Needs a few more/groovier bass speakers. More amps would be nice, but really guitar amps will do for 90% of this--the only real problem with guitar amps is the voicing of the tone knobs, and you can usually work around that. (Again the tone control conundrum!)

Only one input jack? No redundancy?
I absolutely agree - we need more bass content on here. If I had to venture a guess, bass players are less than 1% of the users of Axe-Fx stuff. It's funny - there seems to be a lot of push back for reasons I can't comprehend. I think part of it is the history of companies like Line6 overselling modeling, so some people don't think these can sound as good as they truly do. Of course, just normal bias, "what I have is good enough" and it just plain not being a good fit for some players all adds up.

Yup, only one input jack. Though, like a real amp, you could plug into the FX Loop, insert the FX loop block at the beginning of a chain and use that. I can't remember the last time I've had a jack fail on any piece of equipment though, so I'm not worried over it. Also, my AX8 is mounted on a pedal board where the insert/remove of plugs is pretty rare, as the cabling is mostly static.

SeeD, a user on the FAS forum, shot a couple of bass cab IRs at one point, I think of a G-K cab. There's also a cab pack of an Ampeg 4x10 with various mics. Once I get a lot of free time, I'm going to go to the studio and shoot IRs of a few bass cabs and release my own cab pack.

I highly recommend the Ampeg 4x10 series of impulses produced by Ownhammer. Some of the most natural and fullest sounding IRs I've ever auditioned.

Cab Pack 11: ML SV Bass 4x10 UltraRes on the Fractal Audio site is also one of the better IR packs.

Unfortunately, Redwirez has not kept pace with the UltraRes thing, which is too bad because I liked their 8x10 IR pack.

I'm still a big time FAS fan, but over a year ago I loaned out my AxeFxII rig to a guitarist I gig with, and programmed him a handful of presets and Scenes, and he plays it FRFR through an Atomic CLR. Sounds excellent! Now I can't pry it from his cold fingers, but I have to admit that it sounds so incredibly good on guitar that I'm happy to use my other toys for the less demanding work I do with live bass. I miss the AxeFxII, but honestly, it is overkill for most of my gigs, and a lot more gear to lug than I need.

In the meantime, I'm futzing around with the ZOOM B3, which has taken a back seat lately to my latest experiment using my GK RB1001MkII with the ZOOM G5n on the floor providing stomp effects and tuner (mostly because it has more switches than the B3). I'm hoping that they develop bass amp/cab models for the G5n, as a quality upgrade to the B3. Also waiting to try the new GK Plex preamp/DI that is coming out in June sometime.

If my guitarist friend ever sees his way clear to buying my AxeFxII from me, then I'm definitely throwing down with either the AX8 or the FX8, since they are just far more practical of a footprint than the AxeFxII + MIDI pedal (FCB1010). No doubt, though, that the AxeFxII is still the king of the hill in my book. Great, great gear made by Fractal. If only more bassists showed interest....if only...

I forgot that OH put out the 4x10 pack. I wasn't super impressed with ML's work on the 4x10 - it wasn't bad by any means, but not as good as it could've/should've been, IMO.

The AX8 is, to me, a good bit of a game changer (ugh, I dislike that phrase so much). If you can get away with the lower CPU room, they're fantastic. I love my AX8, though I have a two amp setup in my Axe-Fx II that I can't seem to get away from. I'll be picking up a 2nd AX8 though once they become generally available in the store.
 
Hello Fractal veterans! I recently received my AX8 & too was blown away by the great sounding (guitar) presets. 'Cool' I thought, 'now i'm going to digitally recreate my analog pedalboard'. I got myself some cab IRs, got good amp, comp, drives & modulation happening, then when it came to reproducing my octave pedal (currently Aguilar Octamizer) I couldn't get a satisfactory result. Initially I saw the pitch block, soon realised it is a micropitch-type chorusy thing. So the synth block is the only option for what I want to achieve? The tracking really isn't great on bass is it? Is there any way to improve this? Do I need to learn to 'play the effect' in a new way? I know I could drop the Octamizer in the fx loop but I was hoping to keep things as compact as possible. For $2500 AUD surely it can do a half-decent OC-2...?! Cheers chaps.

I'm not in front of mine at the moment, so I may get the names of the controls wrong. Use the Pitch block, set it to a Fixed harmony, and set it to -1 (or might be -12, or -1 octave).
Another approach is to set to fixed harmony and set to (I think it's called) Octave Divide.

Lastly, another option to try - use the Ring Modulator. Set it to "tracking" mode, and you'll also need/want to use the Hi Cut.
 
Glad to hear it! It definitely has a learning curve, and there are a lot of tricks that you can do to get effects. Some make sense, and there's some goofy ones too. Exploring around and at looking through every page for each block over and over again helps. Sometimes you have to think a bit outside of the box to get where you want to go, and it can be a little bothersome if you're banging against the CPU limit, but there's almost always a work around (using a Pedal compressor instead of studio, dropping the reverb down one notch in quality and so on).

I'm super willing to help anyone get going with one of these. I like helping, and I'm a big, big fan of these. After using them for as long as I have, you learn your way around and find neat little tricks and very cool tones :).
 
Personally, I would disagree that botique pedals are better. They're easier to use, yeah... but Pedal 2 in Axe-Fx to me works just as well as the Cali76 that had, and the Studio compressor is better than any pedal or typical rack compressor (i.e dbx) that I've used as well.

But, it comes down to what you want, and are used to. If a pedal or rack compressor gets you what you want and need and the Fractal stuff doesn't, well, then use that :)
 
I also have AxeFx2 mk1 and the Fx8...
What do you think about the Compression block?
Boutique pedals are better, no?

My hardware compression weapon of choice was always the EL-8 Distressor, so for me there isn't a substitute in the AxeFx or in any outboard pedal. But that said, I've gotten good results from different comps in the AxeFx. Recently, I was using the compressor located in the Amp Block's Dynamics tab as a starting point, in order to avoid having to necessarily use a discrete compressor block. Ideally, I'd like to use the MultiBandComp block, but I never felt that this was effectively tuned well for bass instruments to allow for some of my favorite clinical sculpting in the low end and low-mids (due to limitations of the selectable crossover frequencies).

I liked the Comp Block Studio compressor, engaging the Hi Pass filter to avoid premature pumping from low freq content, and setting it for a +/- 50/50 mix blend to retain attack dynamics. Pedal 2 comp was also one I could live with, but it took quite a bit of futzing and tweaking in order to behave in any way I liked for bass. Never found Pedal 1 to be useful at all.

I personally use Aguilar gear and some pedals.

I also use the Zoom B3.

But I'm getting an Ax8 soon.

My question is: How many kinds of AMPS are available and is there more than the one SVT that comes stock? And then what I mostly want is various types of distortion, overdrive, etc., for when I play. I want to be able to warm up and put some grit in my tone. I find that the B3 fails epically at that, while excelling at almost everything else.

Feedback?
 
I'm not sure what you mean by "how many kinds of amps are available". There's almost 250 amp models in total. With the AX8, you can run any single amp you'd like. Here's a complete list of the amps:
[Invalid or Expired Link Removed]

There's only one SVT modeled, correct. You can, of course, tweak it like crazy to where it doesn't sound anything like an SVT.

There's also a ton of "drive" models available. There's 30 some odd different ones in there... warm fuzz to dirty / raunchy are at your finger tips.

You have a bit of a learning curve a head of you, but if you spend the time to learn the system, you'll find what you're looking for, I think. :)

Fractal Audio stuff is "keeper" stuff. I only sold my Ultra in order to purchase an AxeFxII. There is the SVT amp model, a couple of Mesa 400 models, and an Orange bass amp model. You may want to experiment and dispense of the notion that any one amp model is dedicated for guitar or bass (such as the fender bassman). In fact, way back in the old school days, Marshalls and Hiwatts were generically used by both guitarists and bassists until the industry started to split off and focus on the technical things that make bass amps behave a bit differently than tube guitar amps.

You'll want to experiment with drives, amps, cab sims (or no cab sims), parallel routing, etc. Fractal gear is really great stuff for those who like high quality simplicity, if that's what you desire, or very deep unique sound creation. If you dive in with patience, you'll learn a LOT about sound and audio engineering in general. Definitely join the Fractal Audio Forum.
 
So, I had another "amp model selection" session. Still not totally in love with most of the speaker models, but the amp models are pretty tasty.

I ran into a situation that affected more than one bass amp model (when using default settings). When I would sustain a mote, it made a distortion sound that sounded like crossover distortion. It did not get louder as I increased the input gain, instead getting masked out, but became very audible with a post-amp compressor (my usual setup). Turns out it was coming from one of the 12AX7 models in the preamp... if I take the last stage and very slightly drop its "distortion frequency", it would go away. So, not crossover distortion, but something strange in the models? I'm pretty sure the preamp stages don't make crossover distortion noises when being fed a fairly low input signal, I mean they're class A and everything. :)

I was quickly reminded that blending clean signal with a mic'ed speaker cab leads to phase cancellation at various frequencies, but all I really want is a small amount of additional low end extension. I found that using highpass/lowpass filters at 50-75 hz (depending on cab) to effectively form a crossover, and blend some clean sub bass (highpassed around 25-35 seems to work well. I would normally *not* highpass the bass, but it seems to sound right coming from this box. The sub in my studio room is flat down to 21Hz, so maybe this isn't an issue for live sound in any case. :)

In general, I haven't been able to get an attack/sustain I love from the compressor model. It's not bad, I'm just not in love. I've tried a few different settings for the detector highpass. I am getting decent results with the "normal RMS" setting, detector crossover frequency set low (around 40), 4:1, and only a very small amount of compression on the stronger attacks; this is usable, but it's a) not transparent, and b) not giving me a pleasing "touch" effect on the attacks. Tweaking a new comp is always interesting.

The release on the compressor seems to be a bit too obvious. Not log release? I can't tell with my 100% genuine gold-electroplated ears, but it's just *audible* when it releases. In the transients, I wish it had a bit of the right kind of nonlinearity on the overshoot. And there's just something too obvious about the release curve.

Of course, I'm spoiled. Which is to say, the studio comp is good. :) Bassists tend to be as sensitive to compression as guitarists are to...everything in the guitar amp. But I feel there's room for improvement, bass-touch-wise.

Of course I spend a lot of time on the trouble spots. :) The bass amp tone is absolutely great. If anything, it transitions *too smoothly* into overdrive. (This is not a complaint!) The touch is good, although I need to take it to some gigs before I can really give a judgement on whether the modeling can compare to the real thing...

I'm just starting to play with effects. Aside from the guitar player focus in terms of range of options, they are very great.

Have you mucked around with the Ouput Comp that lives in the Dynamics Tab of the Amp Block? There are just a couple of settings with this comp to be aware of, but I've found that with minimal tweaking, setting this comp for just a couple dB of gain reduction, it seems to sound/feel a bit more natural than any of the other dedicated comp blocks. Not sure why. I'm also a fan of jacking up the Master Volume on the SV Bass model, to exercise the output tube emulation. Of course, for years I had an EL8 Distressor in my rack, so I was quite spoiled.

Another little tip to try is the Preamp emulation in the Cab block, using one of the tape settings. This is just another source of subtle (or not) drive/distortion to add to the mix, in addition to some "finishing" EQ.

Hm, preamp simulation "not available in the AX8", probably why I didn't find it. :) (Also, why is preamp simulation,.. oh I get it, it goes along with the mic-ed cab thing. I keep forgetting people want the sound of a mic.)

I'll keep messing around. Was expecting more from the comps, but I guess that's not a priority for guitar. And so I'm back to this place again.

(Another thing that I actually miss is the "defret" pedal. Not sure how to fake that up, probably some combination of attack-shaping and lowpass. They sound awful in isolation, but in the mix it's quite convincing.)

Apologies. For some reason I thought that the Amp and Cab blocks were left fully compatible with those on the AxeFxII, but I guess that's not the case. Hmmm. Bummer. The Preamp simulation in the cab block is nice for adding harmonic distortion as you'd find overdriving an analog recorder's input stage, etc. I find it can add some nice finishing touch.

I'm a fan of the ZOOM B3 DeFret algorithm, too. It may be the only thing I miss about it, though. Never got around to figuring out a way to craft an automated control modifier that softens the attack just the right amount with a resonant filter in there to give it that "fwamp" attack tone. With the AxeFxII I can see the synth block coming in real handy for something like that.
 
Yeah, the compressor takes a lot of tweaking. I still end up tweaking mine at rehearsals - I hope you're doing a lot of your fiddling at rehearsal/gig level, not bedroom ;). I'd say I easily have 30-40 hours on just my normal compressor block, plus the time I wasted trying to get the multiband to work how I wanted (tip: it won't in its current form for bass, don't waste your time).

I had thought that FAS had logic in their signal processing to not induce phase issues no matter what? I know the Axe-Fx II has DePhase control (the AX8 does not), but that isn't for out of phase alignment between two paths. I could be mistaken about this, it's been awhile since I've used a cab block in a preset :)

I've thought before about trying to get a "fretless on fretted" preset going, but honestly don't know where to start with it... and if I want fretless, I'll just grab my fretless! I may explore that a bit more in the weeks following my GTG.

I recently was talking to someone (can't name drop who) that suggested if we can get schematics to pedals, there may be a better possibility of something happening in that regard. Makes me wonder if I go around and dig up schematics for some of the bass amps if that'd help, too. I'd love to find a B7K schematic, but I'm pretty sure it's held very close to the chest (rightfully so).
