I'd often wondered about -feedback but was too lazy to look it up. Now I know a bit more. there was a bit of chatter about it either in a Vox doco or a Marshall doco - can't recall.
I'm a lot closer to modding the Superbass - unfortunately the bloke who does the best amp work in my region has moved just recently.

There is a resistor on the push/pull pot that shelves off some signal. The value of that resistor can be toyed with, or removed completely. It's 100k right now. I'm gonna try some different values and see what happens. Or maybe remove it completely.

It's really not that bad. Yes, you can get shocked, but not if you go through the proper precautions, which themselves are very simple and rudimentary. If you can work a jumper wire with alligator clips, you can discharge filter caps and be safe.
