Blue Colander GT420 MkII

The GT420 is an overdrive that emulates the character of a cranked tube amp. It has a nice grainy tone with lots of vintage-vibe. It can also be used as “clean-boost” to drive a tube amp into nice saturation.

CONTROL KNOBS:
BASS / TREBLE – pre-distortion EQ (turn counterclockwise to cut, turn clockwise to boost)
DRIVE – gain control
VOLUME – master volume control (pedal can get extremely loud!)

CONTROL SWITCHES:
BASS cut – alters distortion attack and overall low-end content (bottom position is flat, middle position is moderate cut, top position is heavy cut)
TREBLE cut – filters out post-distortion treble (bottom position is flat, middle position is gentle cut, top position is heavy cut)
DRIVE sens (sensitivity) – changes gain range and distortion character (bottom position is low, middle position is medium, top position is high sensitivity)
