A 4 knob preamp/overdrive pedal for guitar, custom built in Japan.

The Knobs & Switch :

Hi.D - Shapes the high frequencies and harmonics

Lo.D - Shapes the mid & low frequencies and overall sound presence

Tone - General low pass filter tone control

Volume - Output volume

Toggle Switch - Fat switch

There's also an internal volume trim control if you want to play with it.

This is not, like so many pedals, yet another variation on the good ol' tubescreamer. This baby has it's own unique voice. Richer and darker tones, killer crunch - the response from everyone who's tried it out has been 'I want one of these'. If you cannot find a sound on this that you don't want to live without, you just aren't trying.

High quality Japanese manufacture, small run custom production and great tones.
