Uncompromised effects, loops, amp switching, floor control, and routing flexibility.

The TC Electronic G-System Integrated Guitar Effects and Controller delivers an uncompromised package of effects, loops, amp switching, floor control, and rig integration. It's equipped with two DSP sections that provide the very highest-quality effects on the market. Choose between a rack and a floor-based setup, decide how the effects are routed, tailor the footswitch layout, and select from more than 25 different onboard effects. And it's all built into a rock-solid roadworthy case with 18 giant chrome switches. Extras include 3-band EQ, a smooth noise gate, MIDI implementation, and a USB port for software updates.

On the Floor or in the Rack?

Do you prefer to have your pedals right next to you or would you rather secure them in your rack? The GFX01 19" 1U effects processor can simply be removed from G-System and rack mounted, leaving the decision up to you. A single cable connects the GFX01 with the G-System floor unit, putting your stomp boxes and messy cables out of sight while keeping the power and control under foot.

Analog "True Bypass" Loops

Preserve your original tone with the four analog true bypass pedal loops, all under preset as well as "on-the-fly" control. A fifth loop can be used for inserting a preamp or a fifth pedal in your setup.

Rock-Solid User Interface

Direct access user interface is via six rotary switch encoders. Not only does the heavy-duty chrome switch protect these encoders housing, but it also protects vital components below. With no vulnerable plastic knobs and no obvious openings, G-System is sealed against dust, dirt, moisture, and spills on stage.

Chromatic Tuner

With the full chromatic tuner you can always keep an eye on your guitar tuning. By pressing and holding the tuner switch, the outputs will mute and precise tuner information will be displayed on the LED. Hitting any switch will instantaneously un-mute the output and send you back into the play mode.

Pre Effects

Effects that are typically used prior to your lead effects are found in the pre effects section. They feature a high-impedance instrument input and full 96kHz/24-bit conversion and processing. This high resolution processing ensures maximum preservation of the guitar's original harmonics, which are vital to the character of any overdrive pedal or preamp.


The filter section allows you to select between touch and manually controlled filters, ranging from wah wah over formats to high peak resonance filters.


The compressor section enables perfect dynamic control of the previous filters including a pumping-style compressor or the more transparent compression style that gives smooth dynamic control and lengthy sustain

Analog Pedal Loops

Any disengaged pedal will eat into your guitar tone. The 4 analog loops in G-System give you full preset control as well as on-the-fly enabling/disabling, allowing "true bypass" of any pedal. The fifth loop is custom designed for preamp insertion. The buffered driver design of the insert loop allows extra-long cable runs with no loss of audio quality.

Amp Switching

Four relay switches give you remote analog control of preamps and amps. Relays are under G-System preset.

Post Effects

The post effects section includes all the traditional effects that belong after the "lead" section.

Noise Gate

The post effect section features an ultrafast noise gate allowing removal of background noise from potential high gain pedals or preamps when not playing.


Modulation effects of your choice, including the famous TC chorus, flangers, phasers, tremolo, vibrato, and more, are available in the modulation section.


The detune feature adds to your stereo image, while whammy and octaves allow for more effected sounds. The regular pitch shifting features up to a 2-octave shift.


The delay section sports more than 6 different effects, including legendary 2290 dynamic delay, reverse delay, tape echo, and more. All delays feature true "spilover" allowing the repeats of the delay to ring out across any preset change. Tap tempo is included and can of course be tied to MIDI clock.


Reverbs from the famous TC pallet are included. Plates, rooms, springs and halls are available in the reverb section, all specifically tuned and tailored for guitar.

But wait there's more . . .

G-System houses many extras. To mention a few, you get an ultrasmooth noise gate and 3-band EQ. A boost function makes your fills or solo stand out at the flick of a switch. All tempo-based effects can be individually controlled by tap tempo or MIDI clock, and numerous parameters are under expression pedal control. The included USB port means you'll be able to keep your G-System up to date with future software releases from TC Electronic.
