Rear Panel

Power Jack

Attach the included power cord here.

USB

The USB jack connects the GSP1101 to a computer and serves two purposes. First, it lets the GSP1101 communicate with the X-Edit Editor/Librarian software. Second, it is used to stream four channels of audio (2 up/2 back) to and from the computer when using the GSP1101 with recording software. USB drivers must be installed prior to using the USB port. These can be found on the included CD.

Footswitch

This 1/4” jack connects the optional FS300 3-button footswitch. Functions include preset up, preset down, and bypass.

Expression

Connect any passive volume pedal here to control nearly any of the GSP1101 effects in real time. See page 40 for more information about assigning parameters to the Expression Pedal.

Configuration Port

5. This RJ45 jack is reserved for future use. Do not connect to an Eth ernet port. The connected device will be damaged.

MIDI In

Connects to MIDI devices, letting them control the GSP1101. The GSP1101 responds to MIDI program changes and CC messages. See page 48 for more information about MIDI.

MIDI Thru

Passes on MIDI signals from the MIDI In jack to MIDI devices downstream. Can also be used for allowing the GSP1101 to transmit MIDI program changes to another device (See page 48 for more information about MIDI.)

GSP0 Owner’s Manual



Mixer Outputs (XLR)

The XLR outputs are designed to connect to a recording device or mixing console. These outputs always have speaker compensation active because they are intended to be connected to a full a range audio system. These outputs can have a fixed output level (+4dBu or –10dBV) or their level can be variably controlled using the front panel Output Level control. See page 44 for information about setting these options.

Ground Lift Switch

If you hear humming or buzzing in the mixer outputs, pressing this button may stop it. This switch lifts pin 1 of the XLR Mixer Outputs from all ground references. This may help break troublesome ground loops that cause hum in the system, especially when both XLR and 1/4” outputs are used together.

Line Outputs

10.

These 1/4” outputs can be plugged into a guitar amplifier or into a mixer or recording device. The front panel Output Level knob controls their level. See page 9 for information about the several output options available for the Line Outputs.

Rear Panel

Loop Left (Mono) Return / Right Return

11.

Use these inputs (along with the Send output) to create an effects or preamp loop.

The GSP1101 Loop provides a mono send/stereo return signal path for use with external effects devices or preamps. When used as an effects loop, it behaves as an on/off serial loop path for an external effects device. When used as a preamp loop, the GSP1101 can switch in an external guitar preamp or use the internal amp modeling preamp. See page 45 for information on configuring the Loop.

Effects Loop Level (-10dBV / +4dBu)

12.

Optimizes gain structure of effects loop return for use with different external devices. When set correctly, this switch improves the noise and distortion performance of the loop return.

When pushed in, sets the gain for use with line level (+4 dBu nominal) devices. The Return gain is reduced. When this switch is in the out position, it sets the gain for -10 dBV (nominal) external devices (commonly battery powered or guitar amplifier units) and the Return gain is increased. Loop send is always –10dBV nominal.

Loop Send

13.

This output sends signal to your effects or to the input of a preamp (see #11 above).

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 DigiTech’s 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.

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 doesn’t 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.
