Guyatone Ultrem Optical Tremolo Pedal
The Guyatone Ultrem Optical Tremolo,based on the optical circuitry used in classic amp tremolo circuits of yesteryear, 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.
With the Guyatone Ultrem several types of tremolo and volume effects are available 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 wasn’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 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.
We could go on and on regarding its features, functions, and sound, but to put it simply the Ultrem is the ultimate Tremolo! 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!
