T.M.K. stands for “too many knobs.” 😀 Designed by Tim Escobedo, this circuit can produce a wide range of fuzzy sounds. There is a good sound clip on his site. Here’s Tim’s list of what the pots do (following the numbering on my version of the schematic):
- pot 1: feedback
pot 2: input impedance
pot 3: gain/color
pot 4: crossover distortion
pot 5: octave/fundamental blend
pot 6: volume
At the time, I was trying out some features in this layout suggested by Chris Gregory, Mark Hammer, and Jim Rayden: ground fill, wider traces, and identifying text. And Chris Gregory <email@example.com> kindly wrote to say that he has verified this layout. His build is shown above.
