Help me understand this schematic (Mach 1, Southern Belle)

[Grubb]

Sorry to resurrect the thread, but I thought this might be the best place to ask another question about the Timmy bass control. If I reverse the wires to the lugs, will this operate more like a conventional control (CCW = cut, CW = add)? Do I also need to change the taper of the pot?

The reason for asking is that I've modded a Mach 1 circuit into a pretty good sounding distortion but increasing gain = increasing Bass, and I want to be able to offset this to some degree by rolling some Bass off. I figured a Timmy control would be appropriate given the origin of the Lightspeed/Mach 1.

According to the PDF for the MXR version of the Timmy the BASS control is already cut CCW and bass-boost CW, but I don't know what the schematic is like for this.

The original Timmy lug order (on a schematic L>R) is 1 2 3, the PedalPCB Tommy is 3 2 1.

As for taper, the Tommy is linear taper so I wouldn't bother changing that.


Best bet is to breadboard it, and try each taper yourselff and see which you like.



In other words, I don't know.
