Used Surfy Industries SurfyVibe Vibrato Guitar Effect Pedal

This SurfyVibe pedal emulates the the mono channel of a Magnatone 280, giving you lush, swirly pitch-shifting vibrato. The "sweeping" mode adds a feedback path to create a unique effect that is a mix of phaser / chorus / tremolo.

The original circuit in the Magnatone 280 used a component called "varistor", a type that has been obsolete for years. This is the reason modern circuits use other techniques to achieve pitch shift. It uses JEFTs and varistors with special diode arrays to achieve this tube-like vibrato. This pedal is in good condition.
