The Alesis QuadraVerb GT is a stereo effects unit that is ideal for guitar. It combines analog and digital electronics to provide the best of both worlds. Analog effects include: •Compression •Distortion • Flat/Presence/Brightness Control • Bass Boost • Speaker Cabinet Simulator (ideal for use with headphones or recording direct; can be bypassed when feeding a guitar amp) • Noise Gate • Programmable Effects Loop for inserting other effects (can also provide a signal send from the analog outputs, and receive a return signal into the digital processor) The digital effects are the same ones that have made the QuadraVerb Plus a favorite in studios and live equipment racks world-wide: •Reverb • Delay (stereo or mono) • Pitch Change (chorus, flange, detune, phaser, etc.) • Equalization (graphic or parametric) • Panning and Tremolo •Ring Modulation • Tunable Resonators (a very resonant filtering effect) • Sampling (up to 1.5 seconds of sound can be captured and replayed) in good condition with power cable open to offers.
