I like the dynamics. Then again, I flicked in back in tonight for a change & the amp tightens up & shimmers a bit more. Didn’t think of the footswitch at the time.

I just put a SPST mini-toggle between the 68k nfb resistor & the output jack. I’m at work & don’t have the layout drawing handy, but when I post some photos next week I’ll point it out. In one position the loop is complete, in the other the circuit is broken (not grounded).

It sounds great both ways! With the loop intact it’s tight & a bit cleaner. With the loop lifted — more dynamics! More squishy overdrive! I debated putting in a pot to get the in between shades, but I’ve decided that on/off is…[Read more]

Very full. Next I’ll set up a cab for the 8/10 combination.

I’ve also put it through a pair of ceramic Blue Dogs in a sealed 212 cab to bring the mids forward.
