Everything has been said below.

It's the same model as the Vexter but it is painted by hand ... This gives an authentic artistic side

This painting is fragile ..

Fuzz pedal with AC128 Germanium transistors. In the distinction of having a button which makes the pedal STAB unstable and generate feedback.
No tone knob .. ale that is a major weakness.
Made popular thanks to Bellamy of Muse.

UTILIZATION

Complicated but that's what's funny. All settings are interraction ..
The volume is very poorly staged: 3 is much too strong, the rest of the race of the button serves no purpose except to his amp Bouzille

SOUND QUALITY

His heavy powerful, but very acute and criada. Bellamy uses large corrections EQ. It is a shame ... where is the TONE knob sniff

OVERALL OPINION

Original pedal, but its unusual with large faults I love her anyway because it kills.
There are some very good alternatives to this pedal in the same spirit (the Devil Inside by jmb experience with a tone knob and a more bold): http://jmb.experience.free.fr
