    Has anyone tried the MXR MC404 on bass? I'm looking for quick access to some of the options the Dunlop 535Q gives, but it doesn't cover the bass frequencies as well. Wondering if the MXR MC404 has quicker access to those frequencies.

    Or, anyone know how easy it would be to dedicate the 6 positions the 535Q's give to be within the 105Q's range of 180 Hz to 1.8 kHZ?

    Specs below.


    MXR MC404
    HF mode (Yellow Inductor)
    • Low pass: 400Hz
    • High pass: 1.9KHz - 2.2KHz
    LF mode (Red Inductor)
    • Low pass: 255Hz - 355Hz
    • High pass: 1.3KHz -1.5KHz

    Dunlop 535Q Wah Range Selector

    1st Position (Full CCW) 440 Hz to 2.2 kHz
    2nd Position 400 Hz to 1.9 kHz
    3rd Position 375 Hz to 1.8 kHz
    4th Position 345 Hz to 1.6 kHz
    5th Position 395 Hz to 1.4 kHz
    6th Position 250 Hz to 1.2 kHz

    This might be the most confusing post I've ever read here. Are you asking if the the guitar wah can be made to sweep down to 180 Hz?

    That is basically what I'm asking, but also if the 6 positions you can dial in on the 535Q can be reassigned to those lower frequencies once you do.
