Volume aluminum pedals well tough
very heavy
an input, output, tuner output

UTILIZATION

To connect, is anyone's guess ...
the action of the pedals is progressive, super soft and perfectly silent: a real treat!
place in the effects loop or upstream of the amp, it always does its job perfectly.

SOUND QUALITY

To beginners, I'd place in the effects loop of my amp rgler finely volume during the game: it works flawlessly as the precision of the pedals allows adjusting the volume to 1 / 10 of Dcibel prs!
since the band's sound is "stabilisquot;, it returns upstream of the amp and allows me to adjust the level of saturation of this (as knob volume on the guitar but more practical)
allows me to have had a 4th, 5th, 6th, etc ... channel!
impossible to return to rear, it became necessary for me crunches and saturation "light"!

OVERALL OPINION

was going to make a point that I use and I become indispensable
Although it is a little but CHRE:
Solid construction, smooth operation, a must in its class, there is nothing more to add ...
