From classic to space age, you'll find every tremolo effect within!

With optical circuitry based on the classic amp tremolo circuits of yesteryear, the Ultrem Optical Tremolo takes the tone of those legendary units and adds a variety of new and useful control features that set it apart from any other stompbox on the market.

Several types of tremolo and volume effects are available with the Ultrem, including oscillator-controlled tremolo and manually controlled volume. Rate of the tremolo can be controlled via tap tempo, the unit's front-mounted speed control, or an optional expression pedal. Dual outputs allow panning of the tremolo effect between two amps or for use as an amp selector/blender in manual volume mode. Depth and Saturation controls allow for precise control of the degree and tonality of the effect as well as for use as a great-sounding overdrive unit when the oscillator is disengaged.

At the heart of the Ultrem is Guyatone's proprietary CPU controller, which allows for quick selection of the Ultrem's primary effect function. Six effect modes are easily accessible from the unit's front panel, and each effect mode features a sub-mode that can be accessed with a quick press of the control footswitch. If that isn't enough, the last two modes also feature bonus modes that allow for manual selection of the oscillator waveform via an external expression pedal.

The six effect modes are as follows:
Wave tap —functions as an oscillator-controlled tremolo with rate determined by tap tempo function of control footswitch
Momentary wave — functions as an oscillator-controlled tremolo when control switch is depressed and held — releasing switch disengages the effect. Rate is determined by unit's speed control
Pedal volume/wave - main mode varies output volume using the optional expression pedal or functions as an oscillator-controlled tremolo in sub-mode. If set to pan on, Ultrem can function as an amp selector/blender in main mode
Pedal depth & wave tap - allows user to vary the depth of the effect by using an optional expression pedal, and also to adjust speed of wave tremolo by tapping tempo, instead of using pre-set controls
Pedal speed 1/touch — main mode varies the speed of the wave form oscillation with the optional expression pedal over a range of 70-1000 ms. In sub mode the unit functions as standard tremolo
Pedal speed 2/touch — main mode varies the speed of the wave form oscillation with the optional expression pedal over a range of 70-4000 ms. In sub mode the unit functions as standard tremolo

By using these different effect modes, you can achieve a limitless variety of tremolo and volume effects that can all be toggled through and tweaked in real time.

The Ultrem's CPU also offers six selectable waveforms when the unit is used in the oscillator-controlled effect modes - a variety of Triangle, Sawtooth, and Square Waves are available for quick selection via the unit's front panel, allowing the Ultrem to mimic any tremolo type from the smooth, rolling tone of vintage amps to the tight "helicopter" chop so popular in today's music. In addition, the oscillator's rate can be displayed in BPM or milliseconds, allowing for precise syncing to song tempo or external devices.

The Ultrem also features an "auto-start" function that engages the Tremolo effect whenever there is an input signal and disengages when input signal returns to zero. This allows for "quick start" tremolo that will be perfectly timed with the musical passage. The input sensitivity of this feature can be adjusted via an internal Trim Pot to allow use with a variety of different instruments and input signals.

Guyatone Ultrem Optical Tremolo Effects Pedal Features:

  • Selectable Manual-controlled or sscillator-controlled operation with stereo outputs
  • Speed, Depth, and Saturation (overdrive) Controls with switchable Dry Blend and stereo Panning option
  • CV control of tremolo Rate or Depth with 3-selectable pedal tapers (linear, audio, reverse audio). Also functions as volume pedal or amp Panner in Manual mode
  • 6 Selectable waveforms in oscillator mode with tap tempo rate control
  • 3-Digit LED display indicates oscillator Rate in BPM or M/Sec (selectable)
  • Selectable input sensitivity via internal trim pot

Whether you are looking to replace your vintage amps and stompboxes or create an entire new range of effects, the Ultrem is a one-man audio arsenal! Call or click today to order.
