Ol' Ephraim is a germanium powered fuzz that’s easy to handle but roars like a grizzly.
It’s labeled a ‘sustainer’ because it’s not exactly a fuzz and not exactly a distortion. In short, its sound character is like a germanium fuzz, but it’s consistent, reliable, easy to use and has the dirt level of a distortion pedal.
If you love the sound of a small tube amp wound up to 10, you’re gonna dig Ol’ Ephraim. It uses four hand-tested, low-leakage germanium diodes to get those iconic sounds while keeping it as simple and easy to use as possible to call them up on command.
