I've got a funky 60s EKO Viscount made in Italy head that was supposedly owned by Johnny Depp that I've been tinkering with. I've successfully made some moves with the insane tonestack of this thing and made it more useable. What I'm looking to do next is to decrease the negative feedback from this circuit but I unfortunately I don't know what I'm doing. If you search on google there's detailed notes from someone that refurbished an EKO Viscount Reverb amp for his nephew (same thing just with reverb). He made up some schematics and I was wondering if someone knew by looking at this picture which resistor I could change to alter the negative feedback.
