Hello everyone! I haven’t been into MTS in quite a while. I have an RM 50 and RM 100. I had the treadplate modded a long time ago from voodoo amps. It’s gain is way over the top. The bottom end is a bit flabby and not defined. I’m looking to pull some of the gain and tighten the low end a but. Maybe get rid of some lows. First off there a small potentiometer on the board soldered in place of a resistor. Not sure what it adjusts. Anyone have an idea on where to start on the board to drop the gain down a bit? I like my ultra xl I modded myself but like I said I’ve not messed with these modules in years and am rusty on where to start with the circuit. Thanks for any help!
