Using the Internal Frequency Trim Pot
Use the internal trim pot to dial in a perfect phase tone.
For even more exibility, this internal trim pot is a coarse frequency range selector. Simply ip the
pedal over, unscrew the four retaining screws (screwdriver not included), and remove the bottom
cover to reveal a tiny trim pot on the upper left-hand side. Reference diagram above.
Set all the way left will allow the lower frequencies to be phasing, all the way right allows more high
end frequencies to pass. This combination of the internal trim pot and the COLOR knob work in
conjunction so you can dial in your specic range perfectly!
