I need a volume pedal

I have a question.

I've ordered a 25k volume pedal for use on my board (EMG pickups on a LP, so the volume knobs are a bitch to ride while playing.....),

so, if I read this right, the volume pedal will actually be working as a 12.5k volume pot?

What are the implications of this?

And possible solutions? (I have no intention of bypassing the volume pots on my guitar as I use them to blend in the middle position and ballance the pickups for clean neck/overdriven bridge switching and what-not.)
well, what value of pots do you have in the lp?

Yes, and no ... If you run it after a pedal, the pedal buffers it so it doesn't load it in the same way (I shoulda made this clearer earlier), EMG's have a MUCH lower output impedance that a passive pup does; therefore the value of the volume pot need not be as high (the reason EMGs' have those low valued pots), they also have a tendency to load less ... truth is if you run the guitar straight into the pedal, yes it will load it, BUT if you're used to running a volume predal than that's what you've been listening to all this time.
The effect is nothing to panic over, it will be like a 500k player changing to a 250k pot, turn the treble up another notch on the amp , and you'll probably never notice it.
Solution, run after a pedal that has some type of active buffering, but remember those EMGs' are buffered anyway, so they are effected much less by the nastiness of signal loss.

Nothing to panic over ... see above...

Again, see above (I jumped the over the unquote tag), it's just something to keep in mind, if you have a guitar that you don't want to lose any of the upper hi end, then don't run a volume pedal directly after it ... BTW, the BOSS Pedals, compensate but putting a very small capacitor across the lugs of the volume pot, at least they do in the FV-50H and L ... Nodoby complains about the 50H and that's only a 250k pot ... :saeek: The L is even lower.
Just something to think about, which is why I brought it up. :cool3:

Thanks for the info.

It's an EB volume, if that makes a difference.


If I run into problems I'll PM you, but I expect things'll work out just fine. I have a "good enough" policy when it comes to tone, so I don't sweat the details.... :)

Ernie Ball volume pedals are another one of those that look like a piece of junk, but they are popular ... somels thrown into the mix is that the BOSS FV series have minimum volume controls which incorporate a second pot as well of a higher impedance. I've never bothered to figure out the implications of that at various settings, but anything over the mute level would raise the impedance back up a bit. The EV-5 Expresion pedal is just a hardwired mono version of the FV's with even lower Z'd pots, that to can be bastardized as a shunt type volume control.

Cool.
