Guitar Amp Channel Switching Pedal

100_1075.JPG
This footswitch pedal was created to channel switch my amp as well as bypass the FX. I didn't realize the Vox Valvetronix amp I recently purchased didn't come with a footswitch. Channel switching and FX ON/OFF is accomplished using a TRS (Tip, Ring, Sleeve) input on the rear of the amp.

This is a very simple circuit to build and therefore is a very short instructable.

Gather Tools and Materials

I found a great low-profile enclosure to use for this. You can use anything you desire of course.

Additionally:

(2) Heavy duty SPDT footswtches
(2) 1/4" mono audio inputs (sockets)
A soldering iron and solder
Wires
A multimeter to check continuity (optional)

The Amp

This is the amp I designed the footpedal for.

The Footswitch Input

On the rear of the amp is the TRS input.

The Enclosure

I found this great low-profile enclosure at a surplus store. It's been used for various projects. I painted it black.

The Circuit

The circuit is so simple, you shouldn't require a PCB or schematic. Just looking at how the basic components are wired should be good enough. It's really that simple.

The TRS Connections

Here I'm showing the TRS cable I used that splits into two mono jacks.
