Congratulations and thank you for purchasing the GSP1101, the rackmount preamp/ processor that works with your existing tone without taking it over. Please take a moment to make sure you have everything thats included with your GSP1101 purchase: GSP1101 Guitar Preamp/Processor Power cord Warranty card USB Driver / X-Edit Editor/Librarian CD

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 DigiTechs exclusive Tone and Effect Libraries, you can also select ready-made combinations of distortion/amp tones using combinations of post-amp effects (Chorus, Modulation, Pitch, Delay, and Reverb). Press either the Tone Library or Effects Library button to gain access to simple-to-use building blocks that will help you create your sound. See page 14 for more information about the Tone and Effects Libraries. The Preamp knobs on the front panel give you easy access to Gain, Bass, Midrange, Treble, and Amp Level settings. The GSP1101 supports up to eight expression links per preset that can control parameters in real-time. With expression links, you can assign parameters to be controlled by MIDI CCs, internal LFOs, or an expression pedal. See page 40 for more information. Since there are many possible ways to connect the GSP1101 to different amps and audio systems, the best place to start is by using the Setup Wizard. The Setup Wizard asks you a few simple questions about how your rig is connected. Through the following screens you will be given several options that will help optimize the GSP1101 with your rig.

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 doesnt have an effects loop. The GSP1101 connects directly to the amplifiers input.
Connect your guitar to the Input on the GSP1101 front panel.
Connect the GSP1101 Line Output to the amps Input.
2. Guitar Amp Loop Return This setup is for when you want to use the GSP1101 as your main tone and effects source and your amp has an effects loop. The GSP1101 1/4 Line Output connects directly to the amplifiers effects return bypassing the amps tone controls.

To use the Setup Wizard 1. Press and hold the Tuner button until the Setup Wizard screen appears in the display 2. The first screen prompts you to select from the seven most common setups we have just reviewed. Use the Edit/Select knob to navigate through these setups and select the one which matches how youll connect the GSP1101. 3. The next series of screens guide you through the different options available for your selected type of setup. Respond to each question and make your selections using the Edit/Select knob. 4. Once all options have been configured, the message Review Your Selections appears. Scroll through these options to ensure they have been answered correctly. Once confirmed, press the Edit/Select knob to complete the configuration process. Youll exit the Wizard and return to the Preset screen. The GSP1101 is now optimized for use with your setup.

The Preset Screen

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 presets name, what amp and cabinet model are being used, and what effects are active. The first line in the Preset screen shows the presets name in big letters. The second line of the Preset screen shows the selected amp model on the left, and the selected cabinet model on the right. They are always highlighted with a white background, even if they are turned off in the preset. The third line of the Preset screen lists abbreviations of the effects. Effects are highlighted with a white background if they are turned on. Effects that are not highlighted are turned off (they have a blue background). The abbreviations for each effect are as follows: WAH CMP DS AMP NG LP EQ FX DLY RVB Wah Compressor Distortion Amp / Preamp / Cabinet Noise Gate Loop (IA for internal amp and EA for external amp when the loop is configured as a preamp loop) 3-band EQ Modulation / Pitch Effects Delay Reverb

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. Press the Edit/Select knob to load the program
Editing a Preset - Tone and Effect Libraries
The GSP1101 is designed to make preset editing and creation easy and intuitive. When creating your own sound, you must first start with an existing preset. Note that the preset you begin with doesnt have to be in the memory location you intend to have it reside, since you can store it to any User preset location during the store procedure. The easiest way to start is by using the Tone Library and Effects Library menus. The Tone Library button will let you select from a variety of pre-programmed amp/distortion tones based on different musical styles. The Effects Library button will let you select from a palette of effects chains, from simple delays to full multi-effect signals with modulation, delay and reverb. Use the Effects Level button to increase or decrease the overall Chorus/FX, Delay and Reverb levels if desired. Using these three controls should get you close to a sound you are after. From there you can then use the Edit/Select knob to navigate through the individual effects for some fine tune edits. To Select a new Tone Library Setting 1. Use the Edit/Select knob to select the preset you wish to edit. 2. If you find a preset close to what you want, you can begin editing the effect parameters by pressing the Edit/Select knob twice and selecting the Effect you want to edit. 3. If you are trying to find something different from the existing presets, begin by using the Tone Library, Effects Library and Effects Level buttons to get close to a sound you want. 4. Press the Edit/Select knob twice to begin selecting the individual Effects to edit their parameters. When you modify a parameter after selecting a Tone or Effects Library, when you return to the Tone or Effects Library screen you will see Custom/<xx> where <xx> is the name of the Tone or Effects LIbrary and Custom means it has been modified.

The individual Compressor models have the following parameters: Compressor Model Compressor CS Compressor Dyna Comp Sustain Sustain Sensitivity Parameters Tone Attack Output Attack Level Level

After selecting the type of effect in this module, its parameters appear in the in the Chorus/ FX menu, below the Position parameter. The following list describes each Chorus/FX effect and their parameters in more detail:

CHORUS

A Chorus adds a short delay to your signal. The delayed signal is modulated in and out of tune and then mixed back with the original signal to create a thicker sound. The GSP1101 includes the following Chorus models: CE CHORUS tc chORUS CHORUS MULTI CHORUS Based on the classic Boss CE-2 Chorus Based on the TC Electronic Chorus DigiTechs Dual Chorus DigiTechs famous Multi Chorus

The individual Chorus models have the following parameters: Chorus Model CE CHoruS TC CHoruS CHORUS MULTI CHORUS Speed Speed Speed Speed Parameters Depth Width Depth Depth Intensity Waveform Waveform Level Level

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 GSP1101 includes the following Flanger Effect models: FLANGER TRIGGERED FLANGER MXR FLANGER EH FLANGER Flanger Model flanger triggered flanger mxr flanger eh flanger

PHASER

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. The rotation of these two speakers produced an interesting combination of the sound panning from side to side. This produced a slight pitch change due to the speed of the sound coming towards, and then going away from the listener. Parameters include: Speed Adjusts the rate (Speed) of the spinning speakers. Ranges from 0 to 99. Intensity Controls the intensity of the effect. Ranges from 0 to 99. Doppler Controls the Pitch Shift effect that is the ratio between the horn and the rotor positions. Ranges from 0 to 99. Crossover Selects the crossover frequency between the horn and rotor. Ranges from 0 (200 Hz) to 99 (1600 Hz).

VibroPan

A vibrato is an effect that modulates the pitch of the incoming signal. This takes the whole signal slightly in and out of tune at a steady pace. The DigiTech VibroPan also incorporates an automatic panner with the vibrato effect that creates a lush chorus-like sound. Parameters include: Speed Adjusts how fast the signal is being modulated. Depth Adjusts the amount of pitch change. Vibrato/Pan Adjusts the amount of panning incorporated with the vibrato effect. When set at 0, this effect is a standard vibrato. As the parameter is turned up, the phase difference of the vibrato signal sent to the two channels is changed until a full stereo image is obtained at 99. Waveform Selects a waveform: Triangle, Sine, or Square. GSP1101 Owners Manual

UnoVibe

Based on the Unicord Uni-VibeTM pedal, Unovibe adds a lush chorus or rotary speaker (vibrato) effect to your tone. Speed Adjusts the rate (Speed) of the chorus modulation or spinning speaker (vibrato) effect. Ranges from 0 to 99. Intensity Controls the intensity of the effect. Ranges from 0 to 99. Chorus/Vibrato Selects either the chorus or vibrato effect. Volume Adjusts the volume of the effect.

XLR Output The GSP1101 XLR Mixer outputs are set to stereo by default. If there is a need to only use one of these outputs, it is best to switch them to be mono outputs (both outputs sum the left/right channels to mono and output the same signal in each output).

To switch the output option for the XLR Mixer Outputs 1. From the Preset screen, press the Edit/Select knob once to enter the Main Menu screen. 2. Turn the Edit/Select knob until I/O Setup is selected and press the knob. 3. Turn the Edit/Select knob and select the XLR Output menu. 4. Press the Edit/Select knob to switch between Stereo or Mono output. 5.

Type of Loop The GSP1101 features a configurable Loop that can be utilized as either an Effects Loop or as a Preamp Loop. Depending on how you intend to use the GSP1101 in your system, you can select the loop to work in either of these two ways. 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 connect an external guitar preamp, or if your guitar amplifier has an effects send/return, you can integrate its preamp with the GSP1101 effects and switch between using an external preamp or the internal GSP1101 amp/preamp modeling. There are three options for how the GSP110 Loop can be configured: Effect Loop This option configures the Loop to behave like a standard series effects loop. External effects are connected as if they were inline effects that are switched in and out. If the external effect has an effect balance or mix control, this control should be set to a 50/50 mix of wet/dry signal. External Preamp Only This option configures the Loop as a global external loop for use with your favorite preamp. All presets will utilize the external preamp as the primary tone source and bypass any GSP1101 amp/preamp models even if they are active in the preset. Only use this option if you do not ever want to use any of the internal amp/preamp models the GSP1101 has to offer. Int/Ext Preamp This option configures the Loop to work with both an external preamp source and the internal GSP1101 amp/preamp models. This option lets you switch between internal and external preamp sources and program them on a preset basis. To change the Type of Loop options 1. From the Preset screen, press the Edit/Select knob once to enter the Main Menu screen.
