    Hello, ive got a holy stain and wanted to know which pedals apart from the ones listed in the instructions work with it.

    in a store they offered me a Boss FV50H but its kinda expensive and anyways i dont know if it works with it.

    Thanks in advance.

    Some expression pedals are certainly built better than others.

    But I do just fine with an M-Audio EX-P, and they are relatively inexpensive.

    Been considering making my own expression pedal for my Holy Stain. is it correct that all I need do is connect a volume pot to a single 1/4′ jack? Seems too simple…….

    I don’t know about a wah, but I heard that an expression pedal is pretty much the same as a volume pedal and to make one all you need is a volume pot and a single 1/4′ jack. Does anybody know if this is right? If so, I might make my own as I only need one for the pitch shift on my Holy Stain.
    Thanks

    A volume pedal is a bit different from an expression pedal. Expression pedals have a TRS connector with all three terminals of the pot connected to the three terminals on the TRS connector. T = Pot Wiper, R = Toe Down Pot connection, S = Toe Up Pot connection. A volume pedal only has a TS connector, where T = Wiper and S = Toe Up Pot Connection (or ground). The input to the volume pedal is connected to the Toe Down Pot connection.

    For the expression pedal input on the majority of EHX pedals, a volume pedal will not work as well as an actual expression pedal. So I recommend you get an actual expression pedal to connect to the expression pedal inputs of EHX pedals.

    I believe the Boss FV50H is just a volume pedal and not an expression pedal though I could be wrong about that. If you want a very durable expression pedal (many are not that durable) try the Boss FV-500L. The FV-500H will probably also work fine but the lower impedance of the 500L is better suited for the Holy Stain and most other EHX expression pedal inputs.
