For many years, the Boss HM-2 Heavy Metal pedal has been a favorite of metal guitarists for it's unique and distinctive, brutal distortion and tone. Many users just run everything dimed (which is awesome enough in itself), but I've actually found a lot of great & useable tones in it after modding it for use with a bass. I added a mids control, lowered the low control's frequency and boosted the overall output. This one comes in a polished and etched 1590B with all top jacks and a relayed true bypass. This pedal 100% hand made in USA by me.
