    Hey everyone. I've got an EHX bass micro synth with a bit of a problem. It worked fine when I got it, but now the slider for distortion doesn't work properly. With the distortion slider all the way down, there is still distortion added. It seems like its stuck at a minimum of 1/4 of the way from the bottom normally. Does anyone know what might be causing it?

    I've heard that these have problems when the sliders get dirty, could that be causing this?



    thanks everybody

    Yeah, sounds like a dirty slider to me. Get some spray contact cleaner (like Caig's), spray a quick burst in there, and work the slider up and down a bunch of times. Should clear up any issues.

    Does it still make sound even with all the "Voice Mix" sliders set to zero? If it does, I can't help. If not, it might be this:

    (I have the older Bass Micro Synth (not the XO version) and this relates to the older model, not sure if it applies to the new one*)

    There's a trim pot accessible through the bottom of the unit that controls the input gain, it's there so you can tweak it to suit the output of your bass. If this trim pot is turned up too far it causes distortion.

    Try sticking a small screwdriver in there and turning it down (first set all the sliders to zero, except the "Guitar" slider to maximum, and the Stop Freq. to 50%). It's quite sensitive and even just a little movement can result in distortion, so turn it slowly while playing your bass (yes this is fiddly to do!).

    * Apparently you have to remove the base on the newer one, according to the manual.

    Should I use the regular Caig's deoxit or the version that has the included lubricant? I see on other threads to use the lube one for pots and faders, or things with moving contact parts...so that makes me think I should use it for this?

    Given the choice I'd go with the lube version, but ultimately it doesn't matter too much.

    Hey bongo thanks a lot I got some cleaner and sprayed it in there and now everything works great! saved me about 20 bucks over taking it to a store. Got a gigantic spray bottle of cleaner for 8 bucks.

    cheers!
