Among the most versatile rackmount guitar preamps on the planet.

The DigiTech GSP1101 Gutiar Effects Processor is not just any ordinary preamp; it is designed to work with external amplifiers and rigs to preserve your core tone. By allowing you to switch between external preamps and internal preamps, then adding internal stompboxes, wahs, effects, delays and lush Lexicon reverbs, the GSP1101 is the most versatile rackmount guitar preamp on the planet.

The GSP1101 features balanced XLR outputs for direct recording, USB for programming and direct to computer recording. A flexible preamp loop allows the GSP1101 to be easily connected into any rig.

  • Great versatility

    As reviewed by Davis on 12/17/2010

    I have owned mine for over a month and feel that this was one of the best purchases I have made since playing guitar. I no longer use amp sound for live performance, but rather use the preamp as my tone and run direct to the PA system. The ground switch really helped clean up the live tone reducing the feedback which I always had with my old Marshall AVT150. Currently running this through an Epiphone Valve Junior and an EH 22 Cal power amp for some stage volume and practice around the house. My only beef has been with the software. Managed to get the software downloaded and the USBs mapped and the unit will work fine and connect without issues, but after disconneting and restarting the computer I continue to get an error message that the system is not found. Digitech provided great technical support to get this fixed in a day. No problems since. The models work well. I have not lived enough lifetimes as some to determine whether they match each and every cab model, but the effects are amazing. The tube screamer, metal distortions, and delays all work well and it is great having a tap tempo. Great product and look forward to years of service

  • Only one effect per may still need additional stompboxes with this unit...

    As reviewed by James Hays on 4/23/2014

    I am moving from a Digitech GNX4 to this unit after many happy years of gigging with the GNX4. In transferring my existing presets (which must be done manually, because there is no utility or application available from Digitech to assist you in this type of task), I discovered a real problem with the GSP1101. I have a preset that has both IPS and Chorus on the GNX4. When trying to program this into the GSP1101, I discovered that ALL the effects are in single bank, and you only get to choose 1. So for this effect, I get to detune it, but cannot apply Chorus, unless I buy a standalone Chorus, and run it as an external effect in the external effects loop of the GSP1101. That, or I can buy a pitch shifter, and run the Chorus internally on this patch. So beware if you are "upgrading" from a GNX4 or the like, that for over twice the price, you may still have to go and purchase additional stomp boxes and run them externally, because of the limitations of this unit.

  • Too Much to quickly review...tweakers delight

    As reviewed by Morse on 8/15/2011

    This is American Made! Dual DNA2 processors, lexicon reverbs A ton of tones from squeeky clean to DSL out of control. It's all here and more. Just too much to list. Their website has demos to listen to and custom presets to download for the unit. has to be the most hardware powerful processors out there curtesy of Harman Kardon. The key is also so much of this unit wants a stereo config for the best spacializations. I run this through a Ultramizer pro then to a huge QSC GX5 then to two way 15" speakers. 8' feet apart...look out!
