From the instructions: (It is in the middle where you install the trimpot, maybe it should be at the end
)
When you have finished building your mimosa kit, you will need to adjust the bias
trimpot before the pedal will actually compress. You want to adjust the trimpot so
that you get approximately 1.5-1.7V on the source of Q2. This would be the āSā
eyelet highlighted in yellow.
Or you can just use your ears if you know what compression sounds like. Be sure to
turn the BLEND knob full turn clockwise so that you are hearing 100% wet,
compressed signal and no dry signal. You wil have a very hard time trying to adjust
the compressor bias by ear when you are listening to the dry, uncompressed signal.
