Between a guitar
An output amplifier
Alim: adapter (not sold) or 9V battery (ACCS laborious under the plate).
Swicht On / Off by pressing the pedals.
A little heavy and therefore stable trs coating prevents any dparrage.

Basic Config trs

UTILIZATION

Simply press and hop before Guiguamp!
Mine (uh not that of the general pardon of my ERRF singer) works fine.
Big BMOL: if it is not dyed it impossible not to see, horrible sound becomes especially acute in position (cd down to max).

SOUND QUALITY

The magnitude is not great but it works trs trs well in heavy distortion especially solo.
It is located in the middles plutt / treble. For clean sounds it going, especially on the agreements. For the solos sound like fairly clear.
Small even when BMOL: once triggers the signal loses power then for solos prvoir a Boost to hear a little story that is played.
The sound is vintage trs for a first prize. So for a Wah Wah by CHRE I recommend. For other conimiser be a little high and hit it.

OVERALL OPINION

It is not me but it does not fawn all done to please me.
