Hi everyone,
I've been reading a little more about the sonic differences between the Greer Lightspeed and Southland overdrives and the general consensus seems to be that the Southland is more "mid-scooped" (in addition to the differences in gain).
Looking at the PedalPCB schematics for the Mach1 (Lightspeed) and Southern Belle (Southland) and reading this post from @Markus Kersius, the only differences are:
Given that the tone pots are the same, I'm curious to know what is creating the Southland's "mid-scoop"...the difference in the other pots, R4, or something else?

LS:
a100 vol, a10k tone, a500k gain, R4=4k7, and opa2134 ic
SL:
a 250k vol, a10k tone, a1meg gain, R4=22k, 2 extra Bat41's, and tl072 ic
