Wah Pedal as an Expression Pedal?

    Thick Question:
    I have a BOSS SYB-5 Bass Synthesizer pedal and I've been reading the owner's manual which makes mention of the expression pedal which plugs into the EXP jack. I have no clue what an expression pedal is or what they're for but the manual recommends using the Roland EV-5 which I don't own. However, I do own a Cry Baby Bass wah and was wondering if that would work in place of the expression pedal?

  2. No, the EV-5 is a Tip Ring Sleeve (TRS) design, and your Wah is just Tip Sleeve (TS).

  4. Good suggestion Alfonso.

    I was in a hurry when I posted previously, but have now found the refit that I meant to post earlier:
    HACK: CryBaby as Expression Pedal !!

    The key really is this part
    Determine what controls your effect pedal (Syb-5) can do, and decide whether you want to control that parameter — maybe you don't even need an expression pedal! (controls filter cut-off and LFO rate, maybe something else)

    For example, my Elements has expression in, Dr Scientist's manual says I need a TRS, 50k-Ohm expression pedal. What does it control? The dry/wet mix, clean and distorted. I don't recall ever plugging an expression pedal into it.

    My M5 needs a 10k-Ohm TS expression pedal, and with all the things an M5 can do (it's a cool MFX), I could control the Flanger rate, or use the expression pedal as a Wah, or use it like a Digitech Whammy, go from a small hall to a large cavern on a Reverb patch ... — yet, TS is NOT a common expression pedal type (most Exp.Peds are TSR — thanks Line6! :eyebrow:) and the Line6 expression pedal is less-than-fantastic plastic. I found all this out when I plugged my TSR Yamaha expression pedal into it and it did nothing. Instead of using the flimsy cheap Line6 exp.ped, or an expensive Mission wah-style exp.ped, I'm making my own little expression box with a big knob I can turn with my toe...

    So, you can see there can be a lot of variation. Roland doesn't list the EV-5's pot value in the manual nor online (THANKS ROLAND! :meh:), but I've read somewhere it's a 10k pot. I've seen expression pedals with 15k, 25k and of course my Elements needs 50k, sssssoooooo... yeah. Lots of variables out there, gotta make sure it's compatible.
