can you mod a volume pedal to 10k?

[sach16]

Hi all,

I bought an Ernie Ball volume pedal (25k log. pot) to use as an expression pedal on my eventide eclipse which i've now found out needs a linear pot of between 5k and 20k.

On the ernie ball site it says pedal pots should not be modded - but manufacturers always say things like that! does anyone know if its possible /worth getting a tech to d, or is it definitely not gonna work?

Or can anyone recommend a decent robust 10k linear vol pedal with a good sweep range (more sweep than those roland ev5s)?

thanks for the help!

You'll probably have better luck looking for something that is designed to be an expression pedal rather than a volume pedal. Vol pedals have log (audio) taper pots because our ears respond to volume in a nonlinear fashion. An expression pedal is designed to feed a linear resistance/voltage gradient to electronics, which is what you want, otherwise you'll have your parameters changing a lot for a little pedal sweep at one end of its travel and only a little for the same amout of pedal at the other end. Also, many volume pedals are buffered for an audio signal and won't know what to do with a DC control voltage.

hey, thanks for the reply - i get it now, i need an expression pedal... any ideas on a robust 10k pedal with a good sweep range?
