Nessy Posted August 26, 2013 Share Posted August 26, 2013 (edited) I'm struggling to get my Behringer US600 (Boss PS-5 clone) to work with an expression pedal. Tried with 4 different stereo cables, using a Boss FV500-L; I also wired up a separate 10k linear pot to a stereo jack to rule out expression pedal fault. Both of these methods work with the exp inputs on my Boss and EHX pedals. Basically I'm pretty sure it's down to the Behringer. Works perfectly in all other departments, tracks well. The parameters vaguely change on some settings when a expression's plugged in, but it's warbly, random and sounds like a dying hippo. Gone through 3 US600s (returned 2) so unless there's a serious design fault with just the exp input (I doubt it; I know Behringers get a bad rap but they can't be that bad - their tuner and chorus work great) then I'm stumped. Anyone got any bright ideas? Wondering if they need a different pot in the exp pedal (tried with a 500k log hooked up to stereo jack, no joy), but don't really want to buy loads of variations to try them out (most expressions seem to use something around 10 - 50k linear anyway).

pantherairsoft Posted August 27, 2013 Share Posted August 27, 2013 When you connect the expression pedal do you ensure that it is in the heel position as you connect? It needs this for calibration purposes. I doubt it's the cause, but worth covering all bases. Have you tried it with a Mono lead (I know it says TRS in the manual, but so do many pedals that work fine with a TS lead). Quote Link to comment Share on other sites More sharing options...
Nessy Posted August 27, 2013 Author Share Posted August 27, 2013 Gave it a try with exp pedal in toe up and down positions but no joy, and mono cables don't seem to work either - the pedal fairies aren't being very kind to me on this one. Thanks anyway. Quote Link to comment Share on other sites More sharing options...
