Gliss Drive is a boutique overdrive pedal originally conceived for slide (bottleneck) electric guitar, though it performs well in standard guitar setups as well. It delivers a dynamic, harmonically rich tone with very low noise. The pedal’s behavior ranges from treble boost and mild overdrive to more aggressive sustain or fuzz-adjacent drive, depending on settings. It uses a discrete BJT op-amp based drive circuit, and includes a three-position mode switch to alter the low-frequency response and character of the overdrive. The unit is built to order, features hardwire true bypass switching, and is designed and assembled in Sydney, Australia.
