MB Mini Boost
The MB Mini series of pedals from Markbass is made to the same high quality level as our standard effect line, but uses an ultra-compact, lightweight chassis. Smaller than other stompboxes, these incredible-sounding pedals will fit onto even the most crowded pedal boards, and the 9-12V power requirement means you can use them with any standard power supply.
Give your pedalboard a “boost” with the MB Mini Boost—which also features our Variable Preshape Filter (boosts lows and highs, and cuts mids).
