The Uni-Vibe is arguably the most iconic modulation pedal of all. Its sound is still much sought after by players, long after its 1960s debut and subsequent discontinuation, leading to many pedal manufacturers creating their own take on the design. The latest is ThorpyFX, who tells us that its aim with the new ER-2 has been to create its dream Uni-Vibe.

Following the same solid and compact form factor of previous Thorpy pedals, the ER-2 has an easy to operate four-knob user interface. Besides the standard bypass footswitch, there’s added flexibility via a second (Vib/Cho) that changes between Uni-Vibe Chorus and Vibrato (wet signal only) modes.
