GUPtech Echorus

The GUPtech Echorus is a chorus-delay pedal from GUPtech's Jonny Rock Gear line. GUPtech describes it as "basically a very short echo on which optical vactrol based modulation has been applied to create a warm and organic chorus effect." In other words, the circuit starts from a very short delay and wobbles it with an optical vactrol, the light-dependent component some builders use to get a softer modulation character than a standard chorus. The pedal is listed at £107.00 GBP as of 26 October 2026¹.

Controls

The Echorus keeps its panel small: two knobs, one switch.

The D TIME range is what separates the Echorus from a conventional delay: at roughly 35 to 55 ms, the echo is far too short to hear as repeats, which is exactly the territory where a delayed signal starts to read as a second voice. That is also where the doubler setting comes from¹.

Using it as a doubler

GUPtech says the Echorus "can be used as a doubler effect to expand your sound dimension" when the DEPTH and SPEED controls are set at minimum. With modulation dialed out, the pedal leaves a plain short echo behind the dry signal, the classic doubling arrangement. The TOGGLE switch is the companion control here: it kills the dry signal, so the pedal can be run as the modulated voice on its own rather than blended with the clean guitar¹.

Power and build

The Echorus takes a 9V DC output with negative center and is compatible with a standard 9V adaptor, and a 5mm LED shows the on/off state¹. GUPtech builds all of its pedals in Saguenay, Québec, Canada, and a quickstart guide is available for the pedal¹.
