Mark III circuit board experts chime in

I recently got this red stripe, simul, GEQ, no reverb. It has a R2 volume knob added in the back, replaced power/standby switches, and lead master potentiometer replaced. Everything appears to be installed cleanly and it sounds great. Does anyone see anything else that appears to be changed or modded? Thanks!

It’s a bit hard to see on the pics where the right wire (looking from the rear of the chassis) goes from the R2 volume pot. Can you try to get a pic from a different angle?
Seems like R130 and 131 were removed completely.

Did you buy and return this to Guitar Center?
