Hey. Well I didn't modify the blues breaker PCB, I used EasyEDA to make my own version based on the mods suggested in this thread. Here is my schematic.I'm looking to add a presence control to a pro-10 build. By any chance, you can share with us how you did that for your mod? Thanks
Looking at the pro 2 schematic, it looks like you could replace R10 with a trimpot and add a capacitor between the trimpot and Vref.
C7 in the schematic will have an effect here, not sure what. You could always remove it.
Although the presence is mroe of a set and forget for me. You could always change the caps in the tone section to 33nf or more if there is too much treble. Tha'ts what I did.
