If you want to add extra functionality to your Electro-Harmonix 720 Stereo Looper this American Loopers Aux switch is the one to get, very easy!
We also made the center switch a bit higher to avoid hitting the two switches at a time (see pic). It also has the nice Click-Less switches to make it even nicer!
Dimensions:
4.39 x 2.34 x 1.06
* You will need a TRS Cable for this pedal to work, you can GET IT HERE
