    Searched the interweb and did not find a mod description for my next idea....

    I want to put a pot on the “soft” side of the Volume Soft/Normal tab so the soft volume could be adjusted between zero and “normal”. I see using it as soft being regular playing volume and normal would become a slight boost for leads/solos.

    Here’s the part of the schematic in question.

    I’m having trouble deciphering the schematic symbols and extrapolating them into the proposed mod.

    Oops....wrong schematic. Here’s the correct one for the M3. These symbols make a little more sense to my brain.

    Is it as simple as replacing R46 with a pot? That has to be 2.2 M and not 22M, don’t you think?
