Q: Can I use Crybaby™ potentiometer to control the speed regulation in expression pedal?
A: Yes, the Vibe Machine ™ works great with Crybaby™ Hot Potz II (100kOhm) potentiometer. For example, you can use your unused wah pedal as an expression pedal. Please find the wiring diagram in the Vibe Machine manual.

Q: Does the Vibe Machine™ use a phase modulator optical design?
A: Yes, the Vibe Machine™ is a miniature version of the classic Uni-Vibe®. The optical system located inside the Vibe Machine™ is a special reduced-size reconstruction of the classic Uni-Vibe® modulator. The optical system design in its reduced version completely replaces the electric characteristics of the classic Uni-Vibe® optical system. Given that, the main goal was to make a compact size vibe pedal, the optical system simply had to be small. This optical system is the most complicated part of the Vibe Machine™ and about 18 months of hard work was spent on its design.

Q: What is the purpose of the output buffer jumper in the Vibe Machine V-1?
A: The output buffer jumper activates the buffer behind the Uni-Vibe ® circuit. The buffer reduces any potential interferences and hums. For details, please see the manual. The Vibe Machine V-1 is always true bypass. If the output buffer jumper is set to ON, the buffer is active only when the Vibe Machine is switched on.
