Unleash the beast within your bass with MXR M89 Bass Overdrive Pedal. It's not just another guitar pedal repurposed for bass. The M89 has been meticulously designed to handle the low-frequency resonance of your bass, delivering a fat, gritty punch that never gets thin or weak, unlike typical guitar overdrive pedals.

Only bass overdrive i will ever need

I used many different pedals through years and this is the only one which made me happy...It has this warm organic tube like mid boosted tone which is perfect for what i use it...it can go from a low growl like cliff burton's tone on metallica - master of puppets(listen to his isolated bass track on that song or other songs from that album) all the way up to the fuzzy goodness of a MUSE - starlight...well built, dynamically responsive(more you dig in more it growls), true bypass, great clean blend and just looks great overall(white LED is nice touch to the silver case, very 'rock' looking pedal)
