Kevin Bolembach, president of Godlyke Distribution (parent company for Guyatone), gives a thorough demoing of the company's brand new GST-UO5 Ultron Auto Wah. The Ultron, Kevin says, is basically a tricked-out tribute to the Mu-Tron III envelope filter. The Ultron has an all-analog audio path with digital controllers for added flexibility. The Ultron features six effects mode, expression pedal jack, threshold, peak level, and frequency controls, control switch, true-bypass effect switch, range, drive, and tap/pedal setup switches, optical circuitry, and more. Kevin also introduces the GST-C04 Ultrem Optical Tremolo. The Ultrem features six effect modes, depth, speed, and saturation controls, expression pedal jack, control switch, true-bypass effect switch, pan on/off switch, blend on/off switch, tap/pedal setup switch, and more.
