PRODUCT DESCRIPTION

We couldn’t be more excited about the latest offering from our friends at Gurus: a standalone valve/tube vibrato and spring reverb that just happens to also be a guitar pedal.

Buy from this listings with or without a Stontronics 12v PSU.

Drawing on their experience modelling the Marshall 1959 circuit with the Double Decker and following on from the the superb Optivalve (an optical valve compressor which also just happens to be a pedal), this time they’re channelling one of Leo Fender’s finest – the 1963 Vibroverb circuit. 

The Sinusoid delivers superb warm shimmery valve optical vibrato and real spring reverb – courtesy of a twin Accutronics™ spring tank. It sounds superb (as we’ve come to expect from Gurus) and looks set to be their most popular pedal since the stunning Echosex 2º LTD (limited supplies remaining). Check the superb YouTube demo below, Tone Report’s review or our own first impressions jam with drum machine and Space Echo at the bottom of the page.

For sales in UK/EU the price will include VAT. VAT-free sales are possible to businesses and individuals in the EU (outside the UK) with a valid VAT Number – please get in touch if you wish to buy this way.

We can supply high-quality, Stontronics 12V power supplies that are perfect for all Gurus pedals – you can select the option to add one on this listing. See below for more information about powering these pedals.

SINUSOID FEATURES:
– Two independent effects recallable by Footswitches individually or combined.
– REVERB: a real tube driven analog Reverb circuit equipped with an ACCUTRONICS™ Double springs tank. Fine tuning of the frequencies let us achieve the feeling of those famous vintage 60’s spring reverb tanks.
– VIBRO: a real tube driven Optical tremolo circuit, uses a Sinusoidal Wave coupled with our own Gurus proprietary technology using LDR to perfectly match the character of Vintage Vibrato channels, making it stand out from all the other digital or analog tremolo effect units on the market today.
– Remote outs for connections with analog switchers. This lets you remotely use the pedal and operate it outside of your pedalboard where this might cause undesired mechanical noises. NOTE: Remote switcher must have Clean Contacts, without common ground wiring.

POWERING SINUSOID:
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.
So, be sure to use a standard Negative TIP Power Supply with enough current for optimum performance.

FREQUENCY RESPONSE:

Here you can see the incredible frequency response of Sinusoid, a full range 20-20Khz that makes it suitable for all applications and any instrument.

REVERB:
When designing the Reverb side of Sinusoid, we collaborated with Accutronics™, coupled with our driving circuit, GURUS was able to perfectly reproduce, the same tone, feel, and response of theVintage Spring Reverb Tanks.
GURUS SINUSIOD gives you the sound and feeling of those great famous vintage and now expensive amps of the 60’s.
