Gurus Sinusoid Spring Reverb & Optic Tremolo

Full Description

Inspired by Early 60s American Amps

After tackling the British music scene with the 59 Doubledeck, Gurus Amps looked at the old reverb and tremolo effects on American amps and created the Sinusoid to recreate the classic sounds. As the first 100 analogue, tube driven reverb and vibrato pedal on the market, the Sinusoid was created after extensive research and development to produce the real optical tremolo and analogue reverb of old. Its full frequency range makes the pedal suitable for all applications and any instrument, letting players experiment with the music to create incredibly unique soundscapes.

Two Independent Effects: Reverb & Vibrato

The Sinusoid features 2 independent effects to choose from, with the option to use them separately or combined. A tube amp is used to drive the reverb and tremolo circuits, producing a truly vintage sound with the classic warm characteristics of old amp effects. To achieve the truly 100 analogue reverb circuit, Gurus Amps teamed up with Accutronics to create a double spring bank to perfectly reproduce the same tone, feel, and response of vintage spring reverb tanks. The optical tremolo was achieved by combining a unique sinusoidal wave with Gurus’ propriety technology.

Gurus Amp’s Note on Powering the Sinusoid

The Sinusoid drains around 230mA on 9VDC and 300mA on 12VDC, However, having an internal power output section (1,2W amp) that drives the reverb tank the draining depends by input signal, so it may need up to 400mA on 12VDC. Be sure to use a standard Negative TIP Power Supply with enough current for optimum performance.
