Mesa Boogie Walkabout Mega-thread Part 10

Since we are all throwing in our .02 on this concept:

-The variable HPF is a neat idea (but I never have used one).
-Possibly doubling the overall output, part of the goal being more clean output (I think that means same structure/scale, just louder, right?)
-At venues, the option to send a consistent pre-D.I. signal would be nice (unless that design significantly altered the D.I. quality/tone).
-Speakon connectors would be cool, but no biggie.

If it helped keep down the size, I would be fine with a 2-band (with some overlap) instead of three--and no effects loop.

This reads like I should just get a D-800+, right?

I had the D-800 for a bit. I know there are various factors that affect one's idea of "fast" or "responsive" (which, in my case, might include bone-headed e.q. work or wishful thinking), but for me the D-800 was lightning fast and solid. I even got the sense that it contributed to improved timing. I felt a solid, immediate and even-sounding low end.
But I couldn't get it to slow down!
I was advised to try a few compressor tricks but never made it work.

The Walkabout was my first experience with what I think people refer to as "sag". I like to use palm-mute picking when it works for a song, and that amp would thunk-thunk like nothing I tried up to that point; something about the mid and low-end.
And the overdrive is great. I would set gain around 11:00 or 12:00, sometimes 1:00 depending on the setting, then hit it with a mod'd Sparkle Drive (set more as a dirty boost) and...glorious.
Trying to execute above-my-pay grade, fast staccato fingerstyle parts, the Walkabout might be the slowest feeling amp I have played. But someone smarter might have resolved that with e.q. or more practice.

I seem to always search for a middle ground. I never had all three side-by-side, but the Ashdown ABM500 kind-of gets there. It feels slightly quicker than the Walkabout, but a bit more pillowy and distorted than the D-800. And, when engaged, the tube O.D. is excellent; darker than the Walkabout IIRC.
But the ABM always sounds better to me with the e.q. section disengaged. Adding it to the signal pathway, even set (ideally) flat, just feels different. And those cooling fans are like jet engines (so much louder than a Walkabout).
Plus, each ABM500 I used (early/mid 2000s models) had significant line noise, which I was told is some sort of electrical "leakage" associated with the fans (?).

I actually got the standard D-800 to sound a lot like the ABM ("better" depending on the context), but I never could simulate the (what I'm guessing is) harmonic distortion or sag.
(I waste too much time trying to make amp A sound like amp B.)

I put the titan on an analyzer and noticed a slightly tighter bottom, a little less mid, and a Iittle more treble that is voiced a bit higher. I'll be gigging the titan with a hp filter and flat eq but, I do prefer the wa.
Can you enlighten me on how you measured low end tightness with an "analyzer"?

I think we are talking about entirely different things here.
 
Just the frequency response of the preamp. The titan looked to have a slightly more rolled off bottom, way down low. Is there anything else that I haven't mentioned? I used the preamp of the wa in front of the titans power section and got the result that I wanted. Later tonight I plan to use the proper adaptor to use the wa di into the titan to get use of the tube driver. Unless, I am already using the titans tube driver by using the titans fx return? I do not know for a fact where it is located in the titan circuit.

Sorry for being so low tech about the pic, but the computer at the house I had that saved on has not had any internet connection in over two years.

This very discussion is what makes nailing down design requirements/goals so difficult, aside from the "I prefer black" and "I prefer white" obviously diametrically opposed non-starters. I would guess that even with those of us who love the WA, our favorite attributes might be different amplification artifacts or dynamic response characteristics at operating conditions that are outside the performance envelope used by someone else. The less inherent linearity there is in the response of a circuit over its operating range, the more likely it is to see this issue, at least in mind.

What we each hear and like about something is often more qualitative than scientifically quantitative. Even the most advanced and sophisticated modeling techniques frequently have trouble accurately reflecting a tight/squishy/crunchy/whatever tone that everyone would agree is exactly what that particular attribute sounds like to them. As hard as design problems are, the hardest part is usually figuring out what the real design target is and how to test to verify you hit it, other than "I'll know it when I hear it" :laugh:

It's quite simple really...just come out with a new WA prototype and send one to my house. I'll be glad to beta test it for you Mesa. But, I'm a quite an inflexible judge, just the truth (my truth) will come out of my mouth but I can assure that if the amp passes my tests, it will be no less than the current WA, albeit different, in a positive manner.
 
I don't have anything to contribute to the design discussion except to say that if a more powerful WA sounds or plays different compared to the current WA, instead of calling it a WA+, I suggest giving it a different name. How about Runabout? ;)

Very nice...on multiple counts!

Yeah, you are looking at and trying to describe a multi-dimensional mechanism by basing it on a single, simplistic dimension. There are multiple inter-related things going on here, simple frequency response is probably the least notable variable though it is the easiest to measure and since the damn RTA's have become inexpensive, have given folks access to more information to mis-understand and draw false conclusions on.

Tightness, in the context of the tone/feel I was asking about involves the relationship of power amp's output impedance and it's variations to the harmonic structure and level. These 3 variables inter-relate greatly resulting in what is most commonly perceived as lot end tightness, or lack of tightness, or bloom, or low end bounce, or richness. Sometimes, it's because there are things added that were not there originally, and sometimes because those things are modified in a way that SOME folks perceive as beneficial though other folks may dislike the same effects.

I'm gonna make a bold statement regarding the last 50 pages of this thread: Mesa/Boogie WILL NOT release a new Walkabout amp of ANY KIND. The last 500 posts have been as follows:

"The Walkabout would be perfect if it had X, Y and/or Z"

"Yeah, well, that's a problem. If we change/add X, Y, and/or Z, the amp will not sound anything like a Walkabout"

The Walkabout is its own product, and will go down in history as such. I am now convinced that there is no way to make a version that has more output or headroom, without Frankensteining a 1200-lb. wall of amps such as the ones recently suggested.

So, what's the solution?

1. Buy another Walkabout, a couple more Scout cabs and create the 1200-lb. wall of sound
2. Do #1, but with another Mesa amp (like the Titan V12)
3. Try other amps - a lot of companies are creating bad-arse amps these days. My Hand Box R-400 is on its way to me from Poland, and if it does what it promises, I'll be adding some equipment into the "used Mesa gear for sale" pool.
4. Keep your Walkabout and love it. I'll be the first to admit that it always has a "strained" sound, like it's struggling with the gain, but I don't think that's what is happening. Either way, I have received lots of compliments on the sound of my rig, but like the gear-obsessed idiot I am, I'm in the process of going Bergantino all the way for my cabs. All that being said, I'm 80% sure that I'll be selling my Scout 12" cabs, but I very well may keep the WA head. The Hand Box and Walkabout may end up living in harmony together. :)

All that said, the back-and-forth in this thread is giving me a perpetual headache. It's nothing but constant frustration and zero prospects for a resolution.

Last, if you're in the market for a couple of Scout cabs, keep an eye out in the classifieds or hit me up via PM. I'm going to price them to move. ;)
 
There are multiple inter-related things going on here
...and like all good multivariate equations, the occurrence of predictable, straight-forward linear behavior in any of the relationships is purely fortuitous happenstance that likely only occurs when it's least useful. The only bigger headache is trying to explain that to a marketing guy! :thumbsup:

A conclusion I actually came to as well about a week or two ago. I just didn't have the courage to state it publicly, although I hinted at it a lot. :)
 
Agedhorse. I just got done playing for hours mixing and matching preamp and power amp sections. Without a doubt, for me, the best sound was the walkabout di out, into the titans fx return. Easily. It had all the walkabout tone that I like, but louder and with a slightly more firm bottom. If my opinion mattered, I would suggest using the walkabout entire preamp and driver chain, as is, into the titans power amp and be done. Input gain would be labled pre-gain, the master volume would become a post-gain and the di level would be called master volume. I got all the gain variations that I wanted like that. The wa power section compressing is not part of the sound for me. Yeah, I prefer to use a hp filter in front bit, that seems to be asking too much for some and I could still use an outboard one.
