Greer Amps Black Mountain Crunch Drive – British-style crunch with metal-panel snarl and imbalanced diodes

Big-stack crunch feel · Midrange snarl and texture · Intentionally imbalanced clipping diodes · Works for guitar and bass · 9–18V operation

The Black Mountain Crunch Drive is a crunch-based overdrive rooted in the pursuit of one specific recording of a crunchy British amp—yet it’s flexible enough to cover far more than a single sound. It can simply add believable crunch, or push into the midrange snarl and growl associated with the metal panel era that followed the plexi years, delivering a natural, amp-like response.

A key part of the texture comes from the circuit’s clipping: the two clipping diodes are purposefully imbalanced, chosen specifically to impart the right feel, grain, and crunch for this design. The end result is a drive that evokes big-stack attitude without feeling artificial.

It runs on 9 to 18V DC, letting you tailor headroom and response to your rig. And while it’s made for guitarists, it can sound great on bass too.
