A volume pedal very strong aluminum.
Simple technology, input and one output for the tuner.

UTILIZATION

Very simple job not need instructions!!

SOUND QUALITY

At the top.
The race is perfect.
No breath, this pedal does not affect the sound.

OVERALL OPINION

Very satisfied with my purchase.
A bit expensive new, so I pulled over a secondhand in excellent condition.
Thousand times I would do this choice because it is well worth the price considering the quality.
