Review: Gurus Sinusoid Optic Tremolo & Springs Reverb

December 9, 2016

“Italians! It’s always those gifted Italians,” says director D.W. Griffith after he views the giant elephants erected for the 1915 Panama-Pacific International Exposition in the fictionalized 1987 film, Good Morning, Babylon. (Griffith then hires the two Italian brothers who made the sculptures to do the same for his epic silent movie, Intolerance.) I got the same feeling plugging into the Sinusoid ($435 street), made in Faenza, Italy, by designers Guglielmo Cicognani and Chicco of Guru Amps. The lush reverb and sexy tremolo (inspired by the ’63 Fender Vibroverb amp) are as stunning as a Maserati GranTurismo, a Bvlgari necklace, or an Ermene-gildo Zegna suit. Italians, indeed!

Whether deployed together or separately, the reverb and tremolo elevate your guitar tone to something immersive and magical. There’s a ton of vintage mojo here by way of a 12AU7/ECC82 tube driving both effects, an actual Accutronics Double Springs reverb tank, and an optical tremolo based around a Sinusoidal waveform. Do you get the wideranging parameter control of digital reverb/vibrato emulations or even some stompboxes? Of course not—this box is a marvelous throwback to the old-school world. Do you need comprehensive sound sculpting? Well, ask yourself that question after you launch the Sinusoid and hear your guitar sounding exquisitely juicy, undulating, dimensional, sumptuous, articulate, and drenched in vibe. There may be just four control knobs on this box (Volume, Reverb, Intensity, and Speed), but every sound they devise is inspiring. Like Griffith’s elephants, the Sinusoid is a celebration of wonder.

Kudos Gorgeous sounds.
Concerns Expensive.
