Analog distortion pedal created in the 70's, as told below. Used by Kurt Cobain of Nirvana, among others ...
Ability to create a lot of distortion thanks to the three knobs of the pedal: Tone, Level, Distortion.

Orange, very solid metal casing, the whole is good.

Let's use ...

UTILIZATION

Configuration generally very simple, not need the manual.
Manuel clear, but as said above, it is not needed as the pedal is easy to use.

It is partly for the sound quality ...

SOUND QUALITY

A big fat greasy distortion for amateur grunge.
I use this pedal with a Fender amp and a Squier Harley Benton 20 Watts.

WARNING / \: For maximum effect, it is recommended to use an amp good enough. The mine was not suitable, I was quite disappointed with the sound of the pedal, but my having tried it on a Marshall and it sends the thunder god. : D

OVERALL OPINION

I use it for about a me.
Pedal efficient, not too light, not too heavy, metal box very strong.
Money very interresting because I got to 39 € promotion.
With experience, I hesitate between the latter is the Boss DS-2 Turbo Distortion, after it according to taste.
