Quilter Bass Block

...I was initially very surprised that the BB800 sounded dirtier than my PF20T, an actual tube amp. :)
I've listened to your clips and I can definitely hear some fuzzy distortion (which I didn't like to be honest). Your BB800 sounded really dirty, I still don't understand how a solid state class D amp without an internal drive circuit (think Aguilar or Darkglass) can produce a pleasant distortion. I've read the manual, I play the amp almost every day but this is still a mistery to me.

Yes, the BB800 has some very nice overdrive. If you’re not getting it, it “might” be because the output of your bass is low.
Never heard any overdrive, I use a passive American Professional Fender P bass.

Just use a pre to drive the input signal hot. I tried a tube pre in the input and liked it a lot; really I am not sure if it were A/B'd behind a curtain with a tube amplifier...perhaps many would not know the difference.

I'll try to crank the amp gain or goose it with a clean boost to see what happens, thanks.

I agree it's not a great sound. Fortunately, lowering the Gain and raising the Master cleans it up. For "distortion from the amp" tones I've been very happy with my Quilter 101 Mini guitar head. I don't currently have any gigs that require an 800w amp, so I've been leaving the BB800 at home and bringing the 101 Mini to the monthly blues jam. I also have a nice selection of dirt pedals to choose from. :)

I'm sure you found the sweet spot with just a touch of distortion but less fizzy and farty. How the pedal does this... is still a mistery to me.

The only logical explanation I can think of, is that Pat Quilter is a wizard.

The Voice knob on the 101 is impressive. It lets you switch between 5 different amp sounds, from Fender tweed combo to Marshall stack. I'm told there is no digital emulation, it's an all analog circuit.
 
Cool, if you hit that front end hard enough, it will overdrive. Full bore doesn’t sound so good to me but the Quilter can get a nice soft clip purr going.

This description resonates with mine. Not hitting it full bore but having that soft clip hit when you put an extra bit of emphasis on the note is quite a pleasant type of clipping/breakup/distortion.

Yes, analog. I have one, love on guitar but I will take the bb800 for bass as it is really just as easy to grab.

This is my experience running the tube pre. But one has to be careful to fine tune - not too little and not too much - fine tune it while hitting the notes as one would play live.
 
Never cranked the gain over 7/8 o be honest, I'll try later and report back!

The whole point of the Quilter's Master Wattage knob, instead of Master volume, is that the amp will respond in a way reminiscent of an amp of comparable wattage to where that knob is set.
Put it on "40w", crank the gain, and go.
That's overdrive.

Most tube amps have no "internal drive circuit" but a cranked tube amp gets grindy.
Even solid state amps can get dirty without an "internal drive circuit."
See the GK RB series, and its "on the rails" tone that everyone loves.

I tried with gain on 10 and master low and didn't hear any overdrive. Rolling off the tone knob on my P bass helped a little bit, I was able to hear some light growl when hitting the strings hard but it was barely audible, to be honest. I tried to hit the amp even harder using my Keeley Bassist compressor (set as a boost) and the amp finally started to overdrive. It didn't need a lot of boost to clip, just a touch, but it must come from a pedal in my case, since my P bass has low output. I was really surprised, I've had some fun for an hour or so.
After that, I put the gain back to 6 (I like it there) and used just the Bassist to boost the amp and it worked again, so cranking the amp's gain to 10 is not necessary. Again, rolling of the tone on my bass make the overdrive a little bit smoother, but rolling of treble using the Contour knob on the amp works even better since it seems to tame fizzy treble frequencies. I ended up with cranked tone on bass and Contour around 3 o'clock (4 detents). Cranking the Depth control increases overdrive, of course.
Honestly, I prefer the overdrive sound of my Mini 66 mixed with the clean compression of the amp, but the BB800 overdrive is definitely usable. I MUST try this on a real cab of course, I did all the tests with active monitors and headphones via DI. I'm sure I'll like the sound better on a good cab.

I know how tubes work, the grind comes from them. When I was talking about "internal drive circuits", I named Aguilar and Darkglass brands specifically because they have a drive circuit built into the amp. The BB800 doesn't have this feature, I think we all agree about that.
I've had many (guitar) solid state amps and I tried to push them with boosters and OD pedals to hear how they react and they ALL sounded absolutely HORRIBLE. Solid state amps are clean platforms usually, I need to know how Quilter managed to make the BB800 sound good when overdriven and nobody seems to give a technical reason I can understand.

Are you still not playing this through a cab? Big difference than going through headphones or monitors.
I'll get a cab as soon as I restart playing with my friends, our rehersal room is under maintenance at the moment.

Been using mine as a power section for my MAS cabs and it does a great job so far...used it alone for a few gigs but when listening to recordings made from di i much prefferred the sound of my peavey minimega1000 (that amp just cant push these cabs very well)....so im just lugging them both around as this is a simple solution that gets me the sound i love...
 
Got my BB800 a couple of days ago. Been digging it from the first time I plugged it in. Then today I realized why I liked it so much, because it reminded me of this:

NAD: The BEST Amp I've Ever Heard!! Kustom KXB500

The BB800 and KXB500 sound very similar.

Hi, Low Class

I bought KXB500 based on that thread you started and am still very very happy about it! Thank You! Meanwhile, I was so close to buying Quilter but I end up with Bugera Veyron MOSFET(Zzounds gave a super great deal..)instead. Someday, I will try out Quilter!
