Mr Black Mini OD-503 Overdrive Pedal

The OD-503 is the latest, all original overdrive design from Jack Deville and the other wizards at Mr. Black.  This pedal packs more tone into less space than ever before: the case may be small, but the tone is huge.  The 503 has a snappy, tight feel with tons of bite that's sure to blend well with any amp for maximum overdrive versatility.  The Gain knob takes us from clean-ish to full on distortion, and the pedal cleans up great with your volume knob, maintaining your dynamics while adding that extra bit of push and crunch to your sound.  Like every Mr. Black pedal these are made by hand right here in Portland, OR, so you know you're getting a quality product.  When you need to rock and roll but don't know where to start, try the OD-503!
