Prototype / Lab Units

This category features unique modules straight from the Guru Gara development bench. These units were hand-assembled and used for final design verification, calibration testing, or video demonstrations.

While they may show minor "rack rash" or cosmetic signs of use from testing, they are 100% electronically functional and have been personally inspected to ensure they meet my performance standards.

Why buy a Lab Unit?

  • Direct from the Bench: Each unit was soldered and calibrated by the designer.
  • Tested in Action: These are the exact modules used to finalize the Guru Gara sound.
  • Sustainable Choice: Give a working prototype a home and help us clear the bench for the next design.

Note: All Lab Unit sales are final. Each listing will specify the PCB revision and cosmetic condition.
