Using the GSP1101 Using the GSP1101 GSP1101 Basics The GSP1101 lets you choose from 99 presets, each one a different combination of effects, amp and cab models, EQ and other settings. You can edit, rename, and save presets as well. Note that there are 99 Factory presets and 99 User presets. When shipped from the factory, the Factory and User presets are identical. You can only store changes to the User presets. See page 13 for more information about using presets.
Using the GSP1101 Setup Wizard The Setup Wizard helps you properly connect and configure the GSP1101 for the most common applications, including: 1. Guitar Amp Input – For the amp that doesn’t have an effects loop. The GSP1101 connects directly to the amplifier’s input. Connect your guitar to the Input on the GSP1101 front panel. Connect the GSP1101 Line Output to the amp’s Input. 2.
Using the GSP1101 3. Recording/Mixer – Here the GSP1101 is used in a direct recording setup or run through a full range PA system, with no guitar amps. Connect your guitar to the Input on the GSP1101 front panel.
Using the GSP1101 5. Guitar Amp Effects Loop – Utilizes the GSP1101’s post-amplifier modeling effects such as chorus, delay, and reverb. The amplifier effects send is connected directly to the GSP1101 Loop Return, bypassing all pre-amplifier stompbox effects, amp modeling, noise gate and EQ. Connect the amp’s Loop Send to the GSP1101’s Loop Return. Connect the GSP1101 Line Output to the amp’s Loop Return. Connect your guitar to the amp’s input. 6.
Using the GSP1101 7. Amp Input/Preamp Loop – Integrates the GSP1101 into a guitar amplifier system that has an effects loop. Use this setup when you want to use the tone of your amplifier (rather than the GSP amp modeling) or switch between internal amp models and your amp’s preamp with the pre-amplifier stompbox and post-amplifier effects the GSP1101 offers. Connect your guitar to the Input on the GSP1101 front panel. Connect the GSP1101 Loop Send to the amp’s Input.
Using the GSP1101 The Preset Screen Preset Name Cab Model Amp Model Effects (highlighted are active) When you first turn on the GSP1101, the Graphic display briefly shows the title screen, then the Preset screen appears. Here you can see the preset’s name, what amp and cabinet model are being used, and what effects are active. The first line in the Preset screen shows the preset’s name in big letters.
Using the GSP1101 Selecting a Preset Turn the Edit/Select knob to choose a preset. By default, presets load automatically. The selected preset name appears in the Graphic display and the preset number appears in the numeric display. Presets can be set to be loaded manually (see Preset Load on page 51), so that when you turn the Edit/Select knob the new preset name will appear in the Graphic display and the associated preset number will flash in the Numeric display.
Using the GSP1101 The Tone Library contains the following selections: OVERDRIVE DISTORTION HOT RAT SUSTAINER FUZZOH OVEREASY DIRTY TUBES ROCK 1 ROCK 2 BLUES 1 BLUES 2 METAL 1 METAL 2 COUNTRY 1 COUNTRY 2 WARM DRIVE CRUNCH TEXAS TONE ROCKABILLY SOLO 1 SOLO 2 ROCK WAH CHUNKY SMOOTH HEAVY CLEAN 1 CLEAN 2 BRITISH 1 BRITISH 2 AMERICAN 1 AMERICAN 2 TUBE DRIVE SCOOPED PUNCHY BRIGHT CLEAN BIG PUNCH SUPER GAIN GRINDER BAD BOY LEGACY LEAD The Effects Library contains the following selections: CUSTOM/CHORUS PHASER
Using the GSP1101 Editing a Preset - Individual Parameters Once you have created a sound using the Tone and Effects Libraries, you can further refine the sound by editing the individual parameters within a preset to customize it. After you edit a preset, you must save it or the changes will be lost when you turn off the GSP1101. The GSP1101 comes with 99 Factory presets and 99 User presets. Initially, the User presets are exact copies of the Factory presets. You can only store changes to a User preset.
Using the GSP1101 Editing Expression Links The GSP1101 lets you control parameters with an optional expression pedal or with MIDI CC messages via a MIDI foot controller or computer MIDI sequencer. It’s a two step process: first you assign a MIDI CC number to a “Controller” within the GSP1101, then you assign that Controller to the parameter you want to control. This way, if you change MIDI foot pedals (which often have different MIDI CC assignments), you only have to update the Controllers.
Using the GSP1101 More About Editing Presets Editing a preset is simple. Just press the Edit/Select knob to open the Main Menu screen, turn the Edit/Select knob to scroll through the available parameters and options, and press the Edit/Select knob to select a parameter or change an option. Arrows If a triangular arrow appears to the right of a parameter, it means a sub-menu exists inside that parameter.
Using the GSP1101 Press the Back button (next to the Edit/Select knob) to back out of sub-menus, and eventually return to the preset’s main screen (thus ending the editing session). The Back button DOES NOT cancel changes you’ve made to a preset or menu, but does cancel the Store procedure. Note that you must save any changes you make while editing (using the Store button), or your changes will be lost when the GSP1101 is turned off or a new preset is selected.
Main Menu Screen Main Menu Screen The following describes each of the GSP1101 main menus and their functions. Edit Effects / Preset Select this to open a sub-menu populated with all the effects, amp models and cab models the GSP1101 has to offer, plus options for assigning Expression Links, setting the Seamless Time, adjusting LFO Settings, and the Preset Level. Select any item in this sub-menu to open its own sub-menu, where you can adjust individual settings and parameters.

As an Effects Loop, the GSP1101 offers a way to connect an external effects device that can be turned on and off within the signal chain. When configured as a Preamp Loop, you can switch between using an external preamp or the internal GSP1101 amp/preamp modeling. See page 45 for more information about using the loop.
The Edit Effects/Preset Screen CHORUS/FX The Chorus/FX menu in the GSP1101 offers a long list of modulated effects, including Choruses, Flangers, Phasers, Vibrato, Rotary Speaker, Tremolo, Panner, Envelope Filter (auto wah), AutoYa™, YaYa™, SynthTalk™, Step Filter, DOD FX25, Detune, Whammy™, Pitch Shift, Detune, Harmony Pitch, and Octaver effects. Only one of the effects in this menu can be used at a time. Parameters include: FX On/Off Turns the selected Chorus/FX effect on or off.
The Edit Effects/Preset Screen FLANGER A Flanger uses the same principle as a Chorus but uses a shorter delay time and adds regeneration (or repeats) to the modulating delay. This results in an exaggerated up and down sweeping motion to the effect.
The Edit Effects/Preset Screen VIBRATO The DigiTech Vibrato effect modulates the pitch of the incoming signal at an even rate. Parameters include: Speed Adjusts the rate (Speed) at which the pitch modulates. Ranges from 0 to 99. Depth Adjusts the intensity (Depth) of the modulating pitch. Ranges from 0 to 99. Rotary Speaker The Rotary Speaker emulates a device that included a spinning horn and woofer.

Parameters include: Blend Adjusts the balance between effect signal and dry signal.
The Edit Effects/Preset Screen Pitch Shift A Pitch Shifter copies the incoming signal, then shifts the pitch of the copy to a different note. The shifted note is then mixed back with the original signal, sounding as if two guitars were playing different notes. Parameters include: Shift Amount Selects the interval of the shifted pitch. Ranges from -24 (2 octaves below) to 24 (2 octaves above). Mix Controls the mix level of the shifted pitch. Ranges from 0 to 99.
The Edit Effects/Preset Screen HARMONY PITCH Harmony Pitch makes a copy of the incoming signal, and then changes the pitch of the copied note to a diatonically correct interval specified by the Amount parameter. A Harmony Pitch effect sharpens or flattens the shifted pitch in order to keep the specified interval within the selected key and scale creating a true harmony. Shift Amount Selects the amount or harmony interval for the Harmony Pitch effect.
The Edit Effects/Preset Screen Delay Delay is an effect that records a portion of the incoming signal, and then plays it back a short time later. The recording can repeat just once or several times. Parameters include: Delay Turns the selected Delay model on or off. Model Selects a Delay model.
The Edit Effects/Preset Screen Reverb Using reverb in recorded program material gives the listener a sense that the material is being performed in an actual room or hall. It is this similarity to actual acoustic spaces that makes reverberation a useful tool in recorded music. The GSP1101 features genuine Lexicon® reverbs, whose rich, lush effects have been heard in countless songs, soundtracks, and live performances for decades. Parameters include: Reverb Turns the selected Reverb model on or off.
The Edit Effects/Preset Screen EXPRESSION LINKS Each preset in the GSP1101 can have up to 8 expression links for real-time parameter control during performance. Parameters can be assigned to MIDI CCs, internal LFOs or to expression pedals. The way in which the GSP1101 provides control over parameters is via Global Controllers. These Global Controllers are configured in the CC/Controller Map menu (see page 49). There are 16 Global Controllers that can be assigned in any way to any of the GSP1101 presets.
