Up to 30dB Clean Boost Pedal Designed by BJF.

When you add a One Control Granith Grey Booster to your guitar rig, you'll know for sure that all clean boost pedals are not created equal. The thing that sets the Granith Grey Booster apart from run-of-the-mill boost pedals is that it was designed by legendary Swedish guitar effects pedal maker BJF (Bjorn Juhl Forstarker) Electronics. The result is an incredible amount of available gain, with no detectable distortion or coloration whatsoever. Best of all, the Granith Grey Booster is tiny, so you can add this boost to your pedalboard, without sacrificing valuable real estate.
