SINUSOID INTRODUCTION:
Inspired by the legendary American amps of early 60’, where tremolo and
reverb came into their own, we focused on how to replicate the Vibrato
Channel in a pedal format, our challenge was to design a real Optical
tremolo with same tube driven character of old. We designed Sinusoid
using the ACCUTRONICS™ Springs Tank technology making it 100%
analog, tube driven.
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. Finetuning the frequencies let us
achieve the feeling of those great 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:
Designing the Reverb side of Sinusoid, we collaborated with Accutronics™ this
coupled with our driving circuit, GURUS was able to perfectly reproduce, the
same tone, feel, and response of Vintage Spring Reverb Tanks.GURUS SINUSIOD
gives you the sound and feeling of those great vintage and now expensive amps
of the 60’s.

SINUSOID IN DETAILS:
As you can see on the graphic, your guitar signal keeps always the
SINO waveform, even when the Vibrato does its work. This ensure you
keep always the best tone, respecting your guitar, the others effects you
are using, and the overall performances.
