The DigiTech GSP1101 is a rack-mount multi-effects preamp and processor: a single unit that carries your amp modeling, overdrives and studio effects in the rack instead of on the floor. DigiTech describes it as giving access to over 120 different models, from stompbox overdrives, preamps and amps to studio quality effects including Lexicon reverbs and DigiTech's Whammy pitch effects1.
It is a past product: DigiTech states that past products are no longer in production but may still be available through local and online retailers1.
What the GSP1101 does
The GSP1101 sits in a rack and handles the whole front end of your sound: preamps and amp models, drive pedals, and time-based and studio effects, all in one unit. DigiTech's model list spans stompbox overdrives, preamps and amps, through to studio quality effects, with Lexicon reverbs and the Whammy named among them1. If you are used to floor-based multi-effects units, the GSP1101 is the same idea built for a rack rig, controlled from the front panel or over MIDI rather than by footswitches on the unit itself.
Two Audio DNA2 DSP processors run the effects and amp modeling, with a 24-bit A/D converter and a 44.1 kHz sampling rate throughout1.

Presets and setup
The unit holds 99 user presets and 99 factory presets1. The factory bank gives you ready-made starting sounds; the user bank is where your own edits live.
DigiTech also includes a guided configuration step aimed at getting the unit matched to your rig without working through the manual first1:
"guides you through the steps to optimize the GSP1101 to fit your needs"
DigiTech calls this the Setup Wizard1.
Connections and power
The GSP1101 is USB 2.0 compliant1, giving it a computer connection alongside its audio and MIDI roles. Its power consumption is listed at 22 Watts1, which is mains-level draw: this is a rack processor powered from the wall, not a pedal you can run from a compact pedalboard supply or a battery.
The GSP1101 is discontinued. DigiTech says past products may still be available through local and online retailers1, so new stock is a matter of what is left in the channel.

Questions
Is the DigiTech GSP1101 still in production?
No. DigiTech lists the GSP1101 among its past products, which are no longer in production but may still be available through local and online retailers. If you want one, that means looking at the secondhand market or leftover retailer stock rather than a new unit from the maker.
How many presets does the GSP1101 have?
The GSP1101 holds 99 user presets and 99 factory presets, for 198 memory locations in total. The factory side is read-only and gives you a starting point; the user side is where you save your own edited sounds.
Does the GSP1101 have a USB port?
Yes. DigiTech specifies a USB 2.0 compliant port on the GSP1101, which is how the unit connects to a computer.
How much power does the GSP1101 draw?
DigiTech lists the GSP1101's power consumption at 22 Watts. That is mains-level consumption for a rack processor, not the few hundred milliamps a compact pedal draws, so it runs from wall power rather than a pedal power supply.
Is the GSP1101 a rack unit?
Yes. DigiTech describes the GSP1101 as a rack-mount preamp/processor, so it mounts in a rack case alongside your amp and other outboard equipment.
