    Greetings.

    I just got an older generation guitar micro synth pedal on ebay; (Other than the following issue, I LOVE this pedal!)

    Problem:
    The output volume can sometimes vary GREATLY in response to SLIGHT variations in input volume.
    This is most noticeable when using the square wave, with higher frequencies.

    When I say variation in input volume, I’m primarily referring to normal variations in attack while playing.
    Also, where I am on the neck, or at least which strings I play; For example, the volume often drops when playing the highest (two) strings.

    Furthermore, the volume change is not always smooth and is often a jump, from a roughly constant volume, to a (sometimes insanely) louder one.

    Is my pedal busted, or is this normal?

    Any help would be profoundly appreciated.

    THANKS!!!

    (Fender Strat/Tele through a Marshall Valvestate)

    Sounds like your pedal is busted.

    Thanks for the response.

    If the pedal is busted, I will have to take it up with the seller, ebay, Paypal, etc. So I would like to be as sure as possible. (Unfortunately, none of the shops in town have a pedal on display with which to compare.)

    To confirm, I should not experience any significant volume fluctuations with this pedal, in any setting?

    Thanks again.

    I’d love to hear from as many people as possible.

    … does this seem like a recognizable problem? is it something that can be fixed? Does EHX repair older pedals?

    INPUT GAIN TRIM:

    … okay. originally unaware of the input gain trim, i have adjusted this. however, the results are as follows:

    1. The input gain trim itself JUMPS from quiet to loud, at a certain point, when turning the screw smoothly.
    2. With the input turned up, the effect output volume is more consistent, but the bypass signal is distorted.
    3. With the input turned down, my original problem persists.

    It seems the real problem may be number 1.
    Anybody have any idea why the input trim would jump?
    Can I fix this?

    … Anybody???
