If you have never used a multi-effects processor with your guitar rig, you might be wondering whether the acquisition of a G-•Major will mean days of work ahead. No need to panic! It will NOT take long until your setup with the G•Major behaves as you please and adds to your creativity. With the factory presets your basic needs are most likely covered and you will be set to go within minutes.

But chances are that you probably will like to go beyond factory presets and find a more personalized usage of the G•Major - and that won’t be a hassle either.

Preset Structure - Routings

The G•Major has three routings of the 6 effect blocks.

Serial - where all blocks are lined as a straight line of pedals.

Semi-Parallel - where Delay and Reverb are placed in parallel.

Parallel - where all blocks except Compression and filter MOD blocks are placed in serial

The selected routing is indicated in the display.

Routing Lock

The selection of routing type is saved with each preset, however, you can use the “Routing Lock” function to keep the same Routing in all presets.

Relay and Boost


Changing your sound from a crisp clean dry rhythm sound to an overdriven lead sound, will often involve channel switching of your preamp or combo in addition to changing your effects preset.

To be able to switch amp-channels via MIDI the investment of a separate MIDI switching system is often implied. This is NOT the case when you own a G•Major. With the built in Relay Switching on the G•Major you are able to switch between up to 4 channels on you Preamp/Combo.

Preset Boost Function

Did you ever find yourself needing the occasional boost for fills, phrases or themes? – Probably. If you have controlled your sound using regular stomp-box pedals, you have most likely used a dedicated boost pedal for this. On the other hand - if you are used to control your sound from a MIDI-board you have probably found that you would have liked to have 2 levels of all sounds. With the G•Major you have exactly this option.

All factory presets are saved at –6dB and we suggest you follow this trend when building your own. Setup a single CC-switch on your board to the Preset-boost function and you can toggle between the –6dB standard level and 0dB when that extra level is needed.

External Control – Pedal Boards and Expression Pedals

Guitarists are the most demanding group of practicing musicians when it comes to instant control of sound and effects. The G•Major is nothing less than unique; not only can you control all key parameters via a MIDI board and expression pedals but it is also EASY to set up.

There tend to be two main directions in controlling Guitar sound via any pedal board.

    1. Full preset change for radical changes

    2. “Stomp box” type where only single effects are turned on and off

With the G•Major you don’t have to decide which is for you. With any MIDI board able to send both Program changes and MIDI Cc messages you can utilize the advantages of both the “Preset change” and “Stomp Box” idea described above.

Setting Up

Instead of having to figure out which MIDI messages your board actually sends out and dialing these values into the G•Major – simply let the G•Major detect received messages in >> Learn << mode.


Your MIDI board has 10 switches and one Expression pedal attached. 5 switches on the board sends program changes and 5 send control changes.

On the five switches sending program changes you setup your radical sound changes e.g. 1 for clean, 1 for Crunch and 1 for Overdrive. The last two you might use for special sounds. Each of these sounds you can program with basic effects.

The five switches sending Cc Messages can be used as on/off switches for e.g. Delay, Chorus, Reverb, Compressor, and the last maybe for Tap Tempo.

It is really up to you.

Expression Pedals

Use up to four connected Expression pedals to change parameter values. Which parameter the expression pedal control, is set at preset level. This means that even with a single expression pedal connected you can vary its function form, preset to preset. In one preset it could act as Volume control, in another as a Whammy – or what about free control of Reverb level, the Depth of a Chorus or…..?

The options are endless – and you CAN really express yourself!

TC G•Minor

The G•Minor pedal by TC is a small handy MIDI pedal that interfaces perfectly with the G•Major. Though it has only three switches it can:

  • send MIDI CC messages for block on/off functions
  • send MIDI program changes for preset changes
  • show the status of the G•Major Tuner - right there on the floor


Noise Gate

A Noise Gate is generally used to attenuate the signal when you don’t play the guitar. This way you can avoid hearing the entire hiss, hum and other noise you might have on your system. If you have previously used a dedicated Noise Gate stomp-box or rack-unit, chances are that you have had to compromise finding a setting that matched both the dynamics of your clean sounds and the hiss and noise of the overdriven and distorted sounds.

With the G•Major Noise Gate you do not have to compromise. The Noise Gate settings are saved at preset-level, meaning that you can dedicate the optimal Noise Gate for each preset.


The G•Major EQ is a three band parametric equalizer. Use the EQ as

  • a general compensation to perfectly match you’re the rest of your rig
  • to give radical changes to your sound
  • to give that extra edge on specific sounds when needed


With a full set of standard compression parameters: Threshold, Ratio Attack and Release your compression needs are fully covered whether you need a subtle compression to even out levels, or a hard compression for just that distinct compression that lets the guitar stand out!

Chorus - Flanger

It is more than 25 years ago TC Electronic launched its famous SCF (Stereo Chorus Flanger) pedal. Our experience in that area is undisputed and you will of course also benefit from this in the G•Major Major.

Classic mode offers the high quality Chorus/Flanger with common parameters. The Advanced mode also includes Phase Reverse and Golden Ratio.


A Vibrato effect modulates the incoming pitch. The result is similar to the vibrato technique used by vocalists. As opposed to a Chorus effect, no direct signal is combined with this pitch modulation.

Resonance Filter

The G•Major Resonance filter is basically a Hi Cut filter with adjustable Q-factor (Resonance).With increased Resonance value, the filter peak at the cut-off frequency gets very narrow and steep. This phenomenon is the very core of the characteristic sound of Resonance filters.


There are two effective and good phaser types. The Vintage Phaser will give you the phasing effect similar to the one found in old stomp boxes. The Smooth Phaser is a more subtle type. Excellent for a less dominate effect. The Vintage Phaser utilizes four All-pass filters. These filters create a comb-looking characteristic. When the filtered sound is mixed with the direct sound the “phasing sound” occurs.

The Smooth Phaser utilizes twelve All-pass filters. Due to the higher number of filters in the Smooth Phaser, compared to the Vintage Phaser, the Smooth Phaser simply sounds smoother than the Vintage type.


A Tremolo is basically a change of level controlled by an LFO. The G•Major holds variations from soft and smooth to hard and aggressive Tremolo.


The panner simply pans the signal from Left channel to the Right.



Create truly spacious Delays using the PingPong algorithm that alternates the repeats between Left and Right channels to the extent predefined by you!

Dynamic Delay

The Dynamic Delay initially introduced in the well-recognized TC 2290, is a function that allows the Delay Output level to be actively altered by the dynamics of the Input level. A function that can be used to leave the source material clear and undisturbed while played and delicately accompanied by the Delay between phrases.


The Dual Delay algorithm allows you to have two Delay lines running at the same time. In other terms, you have two separate Delay “units” in parallel, each with its own set of parameters.

Pitch Detune

A Detune effect has a sound that to some extent can be associated with a Chorus effect. The source signal is split and a specified amount of the signal is detuned by an amount of cents specified by you. (100 cents is 1 semitone). The main difference between the Detune effect and the Chorus effect is that the Detune amount does not change. It is a split signal where you simply offset the pitch.

The Detune algorithm in the Pitch block holds two voices. If you think your sound is simply too direct and clean, try out a setting with only a few cents off detune on both voices. - E.g. +2 cents on Voice 1 and -3 on Voice 2.

A Delay for each voice can be applied as e.g. a Slapback effect.


The Whammy effect gives you the opportunity to control the pitch of an added voice with an external MIDI Expression pedal.

Pitch Shifter

With the G•Major Pitch Shifter you are able to add 2 voices, each with a fixed pitch within +/- one octave from the Input note. The processing of the G•Major is at a speed where you will never notice any “searching” for the notes as with many older octaver units or octaver stomp boxes. Try lowering the single Voice to -1200 cents (100 is one semitone). With a Mix level of 100 you will be able to get at pretty good bass-simulation.


TC Electronic, being one of the worlds leading companies in Reverb technology, has put Reverbs in the G•Major that only need a few words of presentation. We have included the Reverb types most used and demanded by Guitar players, with the parameter handles necessary to cover your needs.

We have included the following subtypes:

Spring - for that classic combo amp reverb

Hall - For the large spacious lead

Room - for the generic room simulation at lower decay times

Plate – for the classic grainy reverb
