Dirty Shirley mini twin sister mods.

Anyone know if the bright switch and depth control can be added to a dsm?

I would imagine the bright switch could be, but I’m not sure about the depth. I believe the mini has no negative feedback, and that’s the reason it doesn’t have a presence control so I’m not sure if the depth is possible to be variable.

How close to a PT20 would it be with the bright switch?

I have no idea if the power sections are similar. I like the openness of the shirley, but it would be cool to tighten It up to push it to BEish territory on occasion.

You could add nfb, my highly modded 2 channel pt has it, but you'd change the sound of the amp by doing it.

If you mod it to add nfb can you make to switchable or when the pot is at a min is it basically stock or by adding it it’s always in the circuit even at a min level?
