The Bad Stain Tombstone Distortion Pedal delivers a versatile crunch style distortion at an affordable price. The Tombstone has four different knobs to help you create the distortion sound you desire most. Each knob adjusts whatever it is labeled, making it simple to use. The pedal also features a genuine Winchester 12 gauge shell around the “On” indicator light, giving it the signature Bad Stain look and style. The Tombstone is compatible with any 9 volt DC power supply (Not Included). However, we recommend using a Bad Stain 9 volt power supply because we make money that way. If you’re not 100% satisfied with the BSNW Tombstone Pedal, you should probably buy a different pedal.
