No moving parts or potentiometers means the electro-harmonix Volume Pedal can"t wear out! That"ll really sink in once you"ve been gigging with it a year or two, after seeing the abuse it can take. The Volume Pedal does exactly what its name suggests, and does it well. You get controlled over your bypassed signal level, so you can make sure your guitar sound doesn"t change when you"re not using the Volume Pedal. And because it has dual outputs, it"s easy to integrate a tuner, second effects loop, or second amplifier with the electro-harmonix Volume Pedal.
