Marshall BB-2 Bluesbreaker II - BOOSTER / OVERDRIVE PEDAL EFFECT FOR GUITAR

(This text is machine translated) The Boost function was designed with vintage tube amp users in mind, when you don't want to alter the tone of your amp at all, but want to push the amp into natural overdrive. The Blues mode is reminiscent of the tonal and distortion characteristics of "non-master volume" Marshall amps, such as the classic 60s Bluesbreaker combo.
