Modulation

Vibe

Block 2 variant of ER-2 Uni-Vibe. Different photocell voicing. Made in UK.

True optical Uni-Vibe circuit using a pulsating bulb surrounded by four light-dependent resistors. Block 2 redesign from the original ER-2 with reduced current draw from 150mA to 50mA and improved headroom for handling aggressive fuzz and overdrive input.

Intensity (modulation depth), Offset (changes LFO ramp-up shape for different vibe flavors), Speed, and Volume controls. Two footswitches: On/Off and Vib/Cho toggle selecting fully wet vibrato or wet/dry chorus mix.

Designed for decade-spanning classic Uni-Vibe tones from Hendrix through Robin Trower to David Gilmour. The Offset control is unique, reshaping the LFO waveform beyond what standard Uni-Vibes offer. Named after NASA's ER-2 high-altitude aircraft. 50mA draw, 100mm x 125mm x 53mm.
