Gurus Amps produces great amps and pedals, inspired by the legendary American amps of early 60’, the 1963 Vibroverb, where vibrato and reverb became a necessary tone additive. It was a very difficult challenge for both the Reverb and Vibrato because we could not use the same technology in a pedal due to the low tension. 

For the reverb technology, Gurus involved Accutronics™. that makes the small real springs tanks to fits into the pedal chassis. All of the hard work paid off allowing Gurus to produce the SINUSOID, the first 100% analog, tube driven Reverb - Vibrato pedal on the market.
