Gurus Sinusoid Tremolo & Reverb in excellent condition with box.
The Sinusoid offers a choice of two independent effects, with the option to use them separately or combined. A tube circuit drives the reverb and tremolo, producing authentic vintage effects with the classic warmth associated with vintage amplifiers. To create a truly 100% analog reverb circuit, Gurus Amps teamed up with Accutronics to develop a dual-spring tank that perfectly reproduces the tone, feel, and response of vintage spring reverb units. The optical tremolo was achieved by combining a unique sinusoidal wave with Gurus' proprietary technology.
