View Full Version : Volume pedal placement
04-03-2012, 07:38 PM
Need advice/information regarding placement of a volume pedal on my board. I want to use it to bring delay and reverb in and out of the chain basically.
Can a volume pedal do that or do I need something like a looper?

That would be tricky without a footswitch or something, to patch the signal two separate ways, I'm affraid. Though I'm sure a stereo potentiometer could be wired thus that it splits the signal seamlessly. I know some loopers and sound control units can asign an expression pedal to an output or internal effect (e.g. I know the TC Electronic G-System could).

I was afraid of that - I guess it would not be as a simple as having a volume pedal to control this feature. Thanks for the reply.

Sounds like you want the volume pedal to be a wet/dry mixer. Hmmm.. sounds like a good idea for a homemade pedal.

use one of these on a wet/dry mixer

Seems like this could be done with a parallel effects chain (?)
Guitar -> gain/whatever -> Y-adapter -> 1) volume/reverb/delay 2) direct to next adapter-> Y-adapter -> amp
One of the splits goes to a volume pedal that controls the level of the reverb/delay on the signal and other goes directly to the amp. I would imagine this to be a quick Radio Shack-ish way to try it out.

To do this correctly you are going to want a buffered splitter after your gains (where ever in your chain you would place these two pedals). Delay/verb then VP on the output of that line. Delay and verb set to full wet. Then you need an active combiner to bring the signals back together into one line. Def a more costly setup, but I get what you're going for and you can def make it happen with the right stuff.
The reason the above wouldn't work is that when the VP is completely down you would short your guitar to ground regardless the other line. Think a Les Paul in middle positon. You can mix and balance each pickup together, but though you would think if you rolled off the neck completely you would be back to just bridge. HOWEVER this doesn't work as you short your signal to ground via the neck volume, and regardless the signal still on the bridge, electricity always follows the easiest path to ground.
Active splitter will isolate each line so one doesn't affect the other and preserve tone, but you need an active combiner at the end as well to balance your impedance loads back into one stable low impedance. Would also recommend a phase control on one just incase a certain pedal in one of the lines inverts the signal from the other.

Get a Stereo WET pedal and plug an expression pedal into the mix jack. Done!
Or if you want to get fancy and have both delay and reverb - get a Timeline (or any delay pedal where mix can be assigned to expression) plug both of those into an Expressionator (http://www.jeanbaudin.com/expressionator)- and boom, both can be controlled simultaneously with one expression pedal. And check out Justin's (thru-tone.com) expression mod for the EBjr. Though, this whole thing will be costly but will sound like angels singing.
