Black Effect Pedals Colossa Booster


Black Effect Pedals

This pedal is not a clean boost but a hefty +/- 35 DB "dirty" boost with a extra Dirt (overdirive) control.

The Colossa Booster is a Univox Unidrive based boost/overdrive.

The Colossa Booster loves low tuned guitars and bass heavy amps but also gives "normal" amps a nice deep sound.

The Colossa Booster is a custom developed for Remco Eijssen, guitar player for Colossa.
