Update on the Pignose G40V

So the post-mod "ghost signal" may have just been speaker buzz? I really don't know, 'cause it just kinda vanished and didn't really coincide with anything significant. Anywho it's gone, and after the Power supply recap, shorting switchcraft input jack upgrade with 68K resistor removal of C9 and C21 and change to variable bias, it's good to go...except I broke half of the split shaft on the presence pot.

It's definitely not so harsh and ice-picky anymore, much meatier with nice usable crunch. I appreciate all the input from everyone.

You may be right about the speaker thing. I've had instances where the litz wire between the voice coil and the spade terminals is bent over rubs on the cone or the speaker frame and it could be described as a low-level distortion "ghost signal" sort of thing.

Yeah, but it's buried in the garage at the moment. My bandmaster is acting up now too so I'll probably have to dig it out anyway. Yay tube amps.

Any recommendations for keeping a Quilter Bass Block from slowly vibrating off the cabinet besides “turn the fuck down” or “no really just turn down”? I guess I could just put it on the ground since it does just sorta look like a dorky little bowler hat on a 1x15.

I’ve also seen the 202 guitar head almost fall of a 4x12 so I know it’s just not me.

Looking at some pics online, it seems to have a few holes on a flange on one side, maybe for a rackmount kit. I guess you could run a zip tie through those and the top handle on the cab. Or, if there is a rackmount kit, you could just rack it.

The feet on the bottom look like they come off. You could conceivably replace them with something more massive. If they're not structurally important, you could remove them entirely and put velcro (sorry, "hook and loop fasteners") on the bottom of the Quilter and top of your cab.

I have that problem with my lil Peavey amp, I just tape it to the cab

agreed. Velcro is going to be your best bet here. It wouldn't take much. You might even be able to get away with putting them on the feet of the head depending how the bases are shaped - like it would work better if the feet are flat and not curved or anything, although let's be honest that adhesive doesn't stick to rubber super well. Probably would take the feet off and just do 4 circle pads where each of the feet went and call it good.

If don't want to use velcro I guess you could try bungee or small ratchet straps going to the side handles & over the top? But if it's not good-n-snug it won't do squat. From experience, velcro was best solution I've found.

If the head has any heft or weight to it at all, a small rubber pad that's nicely grippy might do it. Now that I think about it I wonder if moongels might work & would be less permanent than velcro - but you try those, you'll want to remove them after use because they do seem to compost themselves over time and can leave gunk behind.

I guess you could also drill out some small cups for where the feet sit, kinda like the tops of old Ampeg heads...but obviously that's fairly permanent.

Eric just puts his on a small piece of rubber (looks like a small floor mat for a car or something.) That's kept it in place every time I've seen the Bismarck.

You could also just put it on your pedalboard and then run a long speaker cable.

Hook and loop would probably work great. If you want something a little more "pro" feeling i'd take inspiration from fender piggyback hardware, and you could create a bracket or bottom under the Quilter that mounts with thumbscrews to the cab. Little wood/metal/acrylic plate to provide flanges so you could tighten to a cab with shit like so:
