GlassHammer – A PCB project inspired by the Dynamic Overdrive

In stock (can be backordered)



Inspired by the Dynamic Overdrive, the GlassHammer is a fine overdrive with some neat clipping tricks.  The three-way switch allows you to run LED clipping, silicon clipping, or none!  All three have great sounds.

For easy building, there is a comprehensive build document.  The PCB also features E-B-C labeling under the transistor for easy populating, and the project is enjoyable to build.

Includes (1) PCB, you supply all the standard components.

  • LEVEL, TONE, DRIVE, CLIP controls.
  • Works great on its own, or pushing the front end of a tube amp
  • Fun to build!
  • Designed for PCB mounted pots (16mm right angle)
  • Matches up with rullywow 3PDT boards

    This pedal turned out to be an exceptional overdrive, be forewarned it has a ton of drive. Hard to imagine another one could supplant this one.
    Using the 3PDT breakout board made wiring the switch and PCB effortless.
    Thanks so much for making this available!

    The overdrive with clipping off works great. Pushes the clean channel of my MB 5-25 very well. But switching in either clipping option muffles the sound and does not do much. You can hear some clipping but not much. I’ll have to recheck all the diode installs.
