The colorsound inductorless Wah mystery finally solved (I hope)

    I was able to finish the circuit on a perf-board. After some measurements, I found the following settings on the KPA getting the sound quite right:


    FL 173.2050808
    F0 190.4785084
    FH 209.4745836
    Q 5.251754045
    FL 779.4951102
    F0 1155.313357
    FH 1691.398703
    Q 1.266924887

    The resulting KPA settings are:

    Manual Peak Pedal Range Peak Range
    2.168329917 6.323776225 34.15927836 -38 (change this to -41 to get more funk)

    Wow! Nice work! Thanks!

    I created the circuit in Multisim and the simulated results are:

    Manual Peak Pedal Range Peak Range
    2.427292688 4.096057092 44.04398817 12.08828945

    The simulated values are:
