Amp Modelers and Cab Sims

Doppoler

The Gurus Doppoler is a rotary speaker simulation system designed to reproduce the rotary effect in a physical way without the mechanical parts. It is inspired by old yet innovative rotary speaker systems, such as the Maestro Revolver, Leslie, and the "Doppolas rotary speaker" made by Mr. Gilmour & Mr. Taylor. The Doppoler is not a rotary simulator but the brain of a system that, in its best setting, is made of two cabinets positioned at 180° from each other to reproduce the signal as if the speaker is rotating. The Doppoler applies EQ filters, phase changing, volume changing, and calculates how reflections react and affect the signal. The result is an outstanding tridimensional sound that adds ambient and 3D to your sound, even at low speed and intensity without noticeable rotary effect. It features a very transparent tube preamp that respects the instrument's sound and allows for the addition of an overdrive pedal in front of it. Specifications: \- Power In: 12VDC (negative TIP) \- Consumption at 12V: max 300mA \- Input Impedance: ≤1M Ohm \- Output Front Impedance: ≤10K Ohm \- Output Rear Impedance: ≤10K Ohm \- S/N ratio: <90db \- Distortion: max 2% THD \- Estimated tube Life: Up to 5000Hrs \- Width: 90mm (3.5”) \- Length: 130mm (5.1”) \- Height: 50mm (2”) \- Weight: 0.7Kg (1.5lbs) The Doppoler is designed to be used in a pedalboard in front of an amp and can easily add an additional speaker behind the main speaker, such as an active cabinet, a combo amp, or using one of Gurus' Miniamps to drive a guitar speaker.

1959 Doubledecker

The Gurus 1959 Double Decker is a versatile overdrive/preamp pedal inspired by the legendary British tone of 1959. It combines the historic amp tones from blues to hard rock in one device. The pedal features two independent channels equipped with Gain, Volume, and an entire tone stack for sculpting tone. It also includes a post boost with Volume control that can be activated on all three stages of the unit and is self-disengaged by pressing another button. Additionally, the pedal offers a tube FX loop with a series/parallel switch, remote outs for connections with analog switchers, and a balanced/unbalanced D.I. Out with Direct/Emulated option (Speaker Sim. of a 2x12" - V30/SM57) that can be used simultaneously with the standard output of the unit or alone as an interface for excellent quality audio recordings. The 1959 Double Decker is designed to produce rich details, harmonics, and an organic sound with tons of dynamics. It required a lot of engineering work to fit the size, despite using high-quality components normally used in amplifiers and with the important consideration of space. The pedal operates on a standard power supply (9-12VDC Negative tip) and is suitable for use on stage, in the studio, or at home. It is designed to provide excellent starting points for guitar sound and can be connected to a PC with or without a Speaker simulator for high-quality audio recordings.

It is designed to provide the sound and feeling of vintage amps from the 60s.

Tremolo

Doppoler

The Gurus Doppoler is a rotary speaker simulation system designed to reproduce the rotary effect in a physical way without the mechanical parts. It is inspired by old yet innovative rotary speaker systems, such as the Maestro Revolver, Leslie, and the "Doppolas rotary speaker" made by Mr. Gilmour & Mr. Taylor. The Doppoler is not a rotary simulator but the brain of a system that, in its best setting, is made of two cabinets positioned at 180° from each other to reproduce the signal as if the speaker is rotating. The Doppoler applies EQ filters, phase changing, volume changing, and calculates how reflections react and affect the signal. The result is an outstanding tridimensional sound that adds ambient and 3D to your sound, even at low speed and intensity without noticeable rotary effect. It features a very transparent tube preamp that respects the instrument's sound and allows for the addition of an overdrive pedal in front of it. Specifications: \- Power In: 12VDC (negative TIP) \- Consumption at 12V: max 300mA \- Input Impedance: ≤1M Ohm \- Output Front Impedance: ≤10K Ohm \- Output Rear Impedance: ≤10K Ohm \- S/N ratio: <90db \- Distortion: max 2% THD \- Estimated tube Life: Up to 5000Hrs \- Width: 90mm (3.5”) \- Length: 130mm (5.1”) \- Height: 50mm (2”) \- Weight: 0.7Kg (1.5lbs) The Doppoler is designed to be used in a pedalboard in front of an amp and can easily add an additional speaker behind the main speaker, such as an active cabinet, a combo amp, or using one of Gurus' Miniamps to drive a guitar speaker.

Tuners

Echosex 3°

The Echosex 3° by Gurus is a reissue of the legendary Binson Echorec, offering a tube-driven delay effect based on the Maestro Echoplex. The pedal features a self-calibration setting that reads the real-time delay from the unit and perfectly fits it to the BPM set by the user. The redesigned power section runs at 262 volts, providing increased dynamic range and harmonics without input saturation. The filtering section has been cleaned up and redesigned to offer the same rich sound as the previous model but with lower noise and enhanced dynamic response. The Echosex 3° also includes a tap tempo feature, allowing users to set the delay time with precision. The pedal features a "Magic Eye" effect for a psychedelic mood. It operates on a 12VDC power supply with a maximum consumption of 400mA. The dimensions of the pedal are approximately 90 x 50 x 130 mm, and it weighs around 700g. The unit is true bypass with a golden pin relay, ensuring quiet operation with no perceptible noise. The Echosex 3° has been used and endorsed by renowned musicians such as Steve Lukather, Alan Parsons, Doug Aldrich, and many others. It is suitable for a wide range of musical applications, from live performances to studio recordings, and offers a vintage sound with modern functionality.
