The GSP 2101 was the closest thing to an "Axe-Fx" in it's day (mid 90s to 2000).
Full bandwidth stereo effects (20-20kHz).
24-bit signal path, 48-bit internal data path.
Any digital effect can appear at any point in any effects chain. This is what really set this apart. Even some of Digitechs own fx untis that cane well after this one constrained you to preset effect order in signal path. You can even create loops in the 2101.
Number of simultaneous effects limited only by available CPU and RAM blocks. Unit Programmable Algorithms allow you to create an unlimited variety of custom effects configurations.
Effects can be repeated in a chain, e.g. EQ + flange + EQ + pitch shift + pitch shift.
Instant Module and Parameter access.
Multiple dynamic effects capability (e.g. chorus + flange+ pitch shift).
Expandable to 2x factory memory and processing with an optional "artist" upgrade.
Balanced, speaker-compensated outputs for running direct to a mixing console.
World-class tube preamp with six distortion types (3 tube, 3 solid state).
DigiTech’s exclusive modulation delays.
Chromatic tuner.
Effects include: Whammy, Chromatic Pitch Shifter, Harmony Intelligent Pitch Shifting, and Programmable Cabinet Emulation.
Built-in tone generator.
Digital and analog EQ.
MIDI input filtering and MIDI Merging.
MIDI program transmit and receive mapping.
All Effects and Parameters available for MIDI continuous control.
Optional Control One foot controller with built-in Expression Pedal for ultimate programmability and control.
Tone:
Powerful amp sims that are enhanced by the use of a 12AX7 tube used to get tube distortion and warmth. Also has option to use digital effects including distortion and overdrive. Sounds amazing when going into a couple of 1x12 circa '94 boogies. That was my light weight live rig back then up to ~2009.
100 user presets and 140 factory presets equals 240 presets in total, some which were created by some very well known artists i.e. Steve Vai, Steve Stevens, George Lynch, Dweezil Zappa, Warren Dimartini among others.
It was awful to program but once you got it down it was amazing. There were some 3rd party software editors that came along and made things a bit easier. But it was/is a great piece of gear from the 90s.
