Godlyke has released of the Guyatone Optical Series of effect units. The Guyatone Optical Effects are analog/digital hybrids with 100% analog audio paths using custom-made photo couplers. The proprietary CPU controller features a digital oscillator with tap tempo rate control, 6 selectable waveform patterns, and assignable CV control of a variety of parameters.

These units are NOT digital modelers; however they can perform many of the functions of modeling units, bringing the flexibility of digital control to the analog audio domain. Designed as professional-grade products, the Opticals feature many performance options that were previously unavailable in a stompbox format, and they feature a true bypass.

ULTRON – Designed as an improved version of the vintage Mutron III, the Ultron Optical Envelope Filter takes the soul of that classic effect and adds a variety of new and useful control features that set it apart from any other unit on the market. List Price $425.00

• Selectable Manual-, Envelope-, or Oscillator-controlled filter operation
• HP, BP, LP, and Notch Filters with Hi, Lo, and Mid Frequency Ranges
• Variable Threshold, Peak, Frequency and Speed Controls and Up/Down Filter Drive
• CV control of filter sweep (manual mode), Filter Peak or Oscillator Rate (oscillator mode) with 3-selectable pedal tapers (linear, audio, reverse audio)
• 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 Frequency Peak, Frequency Sweep ranges and Input attenuation for multiple instruments via internal DIP switches

ULTREM – Designed to emulate any vintage or current production tremolo unit, the Ultrem Optical Tremolo can also create many all-new sounds custom-tailored by the user for the ultimate in analog tremolo tone. List Price $375.00
