I saw this on Reverb and asked for a gut shot so I thought I would share.
These are the emails from Peter that describe the mods
All-right! The Mini-mu build doc was just put up so I decided to use to document what I can with these mods. The trims all appear to be set in the middle. If anyone cares to add or correct anything please feel free.
This is about the most I can glean from it:
"resistors that set the frequency response & overall feel"
R8 = ? 2M (1M stock)
R26 = ? 10k (4.7k stock)
R20 = 200k (82k stock)
R21 = 200k (82k stock)
R27 = 10k (4.7k stock)
"capacitor that sets the response time for how fast the effect kicks in"
C2 = ? (4.7u stock)
