Product Description

Original TC Electronic G-System Guitar Effects Processor and Loop Switcher
G-System is the first floor-based unit ever to offer both studio-quality guitar effects and advanced loop/routing facilities for external pedals and preamps. With a unique combination of 2 DSP sections, analog loops, amp switching, and 9VDC power outputs for external pedals, G-System is aimed at the experienced guitar player looking to complete his setup with the ultimate in quality, integration and flexibility.

G-System features 8 effect blocks divided into a pre effects section with Filter and Compression, and a post effects section with Noise Gate, Modulation, Pitch, Delay, Reverb, and EQ. Also included are Chromatic Tuner, Tap Tempo and Boost function.

G-System's heavy duty 10 mm aluminum face plate and 18 giant chrome switches ensure unsurpassed mechanical stability, and protection against dust or liquid.

TC Electronic G-System Features

  • Multi-effects processor on the floor
  • Up to 9 effects simultaneously
  • Fast and smooth preset changes featuring delay spill-overs
  • 4 switchable mono-loops for your favorite effect pedals
  • 1 additional loop/insert point dedicated for preamps
  • 4 x 9V DC outlets powering your effect pedals
  • USB connection for software updates
  • Ultimate flexibility as the the board can be separated allowing you to place the GFX01 with loops etc. in a 19-inch rack while leaving the control board on the floor
  • MIDI for control of additional external MIDI units
  • Connections for 2/4 Expression pedals 

The philosophy behind the G-System is that the internal effects can be blended with one or several external effects at the flick of a footswitch. G-System allows for rack or floor based set-ups, flexible routing of external effects, custom-made footswitch layout, and up to 8 effects simultaneously. The 4 analog loops enable true bypass of any pedal, thus preventing disengaged pedals from eating into the guitar tone. The 5th loop is custom designed for pre-amp inserting, and the 4 relay switches give analog control of preamps and amps. Also included are 2 x 2 expression pedal inputs. All functions of the G-System are directly accessible via the 18 chrome footswitches, 6 of which serve as integrated encoders.

The new VPD1 Vintage Pre Drive Pedal from TC Electronic was specifically designed to complement the G-System, featuring classic tube amp dynamics and a special boost section for additional overdrive. Commenting on the new flagship guitar product from TC Electronic, Uffe Kjems Hansen, VP of Product Management, stated: “The G-System is an all-in-one solution that allows the quality-conscious guitar player to combine his favorite stompboxes and preamps with top-notch effect processing from TC Electronic. We believe in the freedom of choice, when it comes to distortion and expression pedals, and have therefore decided to put our focus on flexible loop-switching and superior effects based on TC’s widely acclaimed algorithms. We venture to say that our new product will initiate a paradigm shift in the world of guitar processing.”

Steve Vai Takes Guitar Effects to a New Level – The Floor!
No introduction needed. Source of inspiration to thousands of guitar hopefuls around the globe – the essence of virtuosity – this guy’s a living legend. The intriguing part, however, is yet to come:

Steve Vai Ditches His Effects Racks
That’s right! His entire setup is now down to a G-System plus a few stompboxes and expression pedals. Boldly, you may say that cutting his hair symbolizes cutting with past.

This may come as a serious blow to a great many gear aficionados who for decades have seen Steve Vai as the epitome of inveterate rackism. What’s really intriguing is what drives this icon – a true innovator of guitar settings and playing techniques – to approach TC on his own free will. A guitar authority like him probably drowns in profitable offers from a wide range of manufacturers who’d be just thrilled to see this guitar vanguard use their equipment!

Tested on Zappa Plays Zappa Tour
Taking time off from his tour with Dweezil Zappa; Zappa Plays Zappa, Steve Vai elaborates on his choice of effects setup: For years, I’ve considered TC’s G-Force the ultimate guitar processor simply because it sounds good and is very user-friendly. Only, the G-System is much more convenient because you have everything on the floor right in front of you.

We couldn’t have put it more precisely ourselves. We’ve always believed that unsurpassed quality and user-friendliness are the two paramount parameters when trying to make a stand in the gear jungle. For a floor-based guitar processor, a third and equally important parameter prevails: Durability. It must withstand the repeated punishment of heavy touring activity. We’re just thrilled to see that the real world experts agree with us.
    During the 3 months I’ve had the G-System it’s proven to be very reliable and bulletproof. This is the set up I prefer
    - Steve Vai
You might wonder whether Steve Vai is only gonna use the G-System for guest appearances such as on the ZPZ tour where an easy setup may come in pretty handy and then still require his full conventional racks for headlining and G3 tours.
I’ve programmed it specifically for the ZPZ tour, but during the 3 months I’ve had the G-System, it’s proven to be very reliable and bulletproof this is the set up I prefer. It is also extremely practical in the sense that you don’t need a rack so I have two systems now, one for the road and one which I can leave set up in the studio for recording with.

Driven By Simplicity – Convinced By Quality
Recent years’ reflection upon complexity of life has made Steve Vai realize that changes were inevitable. Although the expression of his work may still remain complex his overall outlook on life is now that of simplicity. When life turns too complex it affects people negatively – I know, ‘cuz I’ve been there explains Vai.

For an artist whose musical trademark has always been anything but that of simplicity, it may appear as a paradox, but, adds Vai: On the contrary – it makes perfect sense to me. It’s kind of a counterbalance to my professional expression.

And the G-System seems to fit right in with that philosophy: Using the cutting-edge digital effects of the G-System while at the same time letting it control the switching between clean and overdrive channels on his Carvin VL100 Legacy amp, punch in/out his Analogman-modded DS1, Keeley-modded Tube Screamer and MXR EVH Phase 90 analog stompboxes while deploying his Morley Bad Horsie 1 wah seems to be the mere manifestation of his devotion to simple living – on stage and off.

IT is well made other than the big plastic buttons.

I've had 2 die just after the 45 day return policy!

Your general opinion of this product.

Not worth the money that's for sure.

feels pretty solid but seems to break down easy.

Effects and tones are TC as usual.

Looks great!

the day i received the 1st one the buttons were sticking and one had fallen out in the bag, sent it back for a new one. Second one died right at the 45 day return cut off and am waiting to find out if i can return it. I play in a band that plays out 1 or twice a month, thank God we were taking a little time off i would really hate to be live and this cut out on me like this. Not reliable for live use, no wonder Steve Vai dumped it.

Years of happiness

Built like a tank and has been on the road for 6 years with me and I've never had an issue. Its held up better than the road case that carries it. That's for sure!

Not a single issue in 6 years

Your general opinion of this product.

Love it..owned it for several years and still as happy today as when I got it.

Top-notch construction. Built like a tank.

I've only had it for two weeks and have used it on nine gigs. Solid as a rock, very simple programing and great looks!

Your general opinion of this product.

I've had it all! Refidgerator racks, heads, combos, pedals and NOTHING ties everything together like the G-System! AWESOME!!!

G-system Limited is a great buy!

Well, they run over it with a tank and it still works. It's not made of sissy plastic like most other products are, the finish it tough and it has some nice weight to it.

Well, time till tell but I don't foresee any problems, I am selling all my other stomp boxes and effects after having this for less than a week.

Your general opinion of this product.

It is a great buy, no more cable mess or endless interconnects. Solid, beefy, sturdy and very well made and you can tell they actually did some thinking when designing this product. Effects are crystal clear with no tone suck. It is very important to think about how something sounds when it is bypassed and this sounds great when not in use as well.

The controls are great and at first I thought I would have to edit them, but I like it now that I got used to setting it up. The top buttons are also dials (which was a brilliant Idea) It's heavy and the buttons press nicely, just tap, they never catch and drag or fail to engage, they just work.

Very clear and you can get absolutely any tones you want out of it, as long as you have the amp to do it with.

The red is very pretty, I don't know about the silver but the one I have has a great finish to it.

The buttons feels great and they turn smoothly and have a nice solid but inaudible clicking like the turrets of a high dollar scope.

Such A Great Unit!

I've only had it for a few months but man this thing is built like a tank. I use to be an analog pedal guy but when it comes to digital no one comes close to TC.

Your general opinion of this product.

I use to use a ground control system but now I use the G-system. It does more than I could have ever imagined. It is expensive but well worth the high quality effects it comes with.

High Quality!

The finish is a sexy red

I will say go to the TC G-system forums to learn to set the system up right for your amp. It took a few days to get everything figured out.

All you will ever need!!!!!

This thing is heavy duty! It is made for the abuse that comes with being on the road all the time.

Have not had any problems so far. Easy to see on stage, easy to adjust on the fly to suit every club you are playing in.

Your general opinion of this product.

Anyone who can't figure this thing out should be playing a horned instrument. Play something that you can blow on instead. This thing is easy to set up and to find great sounding effects to match your tone is an easy task. I was able to set great tones in a matter of 4 hours. I was also able to set up for 3 part harmonies very easily that sound great.

I play through a Krank so my tone is heavy to begin with. Adding the EQ from the G-system defined my sound so well that there is no mistaking the pure greatness of this "Machine". The efects are all high quality and everyone sounds great. This thing is 5 stars all the way down the board.

Whatever you want it to sound like it will sound like.

The overall finish is beautiful with all the great things you look for in a pedal. Lights up nicely and is easy to see from anywhere on stage.

It took a little while to set up but to me if it is playable in less than a half hour it takes the fun out of having something new.

Well a professional should have no trouble with this unit!

Very dependable and built like a tank, just like they say!

This system is more roadworthy and tougher than anything out there by Line 6 or Vox or anyone else. Go ahead and drop it off the front of the stage, it'll be fine, trust me!

Your general opinion of this product.

I've been searching for YEARS for a pedal with great effects and loops and clean tone and have tried several and was always disappointed with all of the above untill I bought the G-System. And as for being hard to program; you'd have to be a complete Moron if you couldn't figure this one out: Ten times easier than PodXt Live and Ten times the features!

This thing is Heavy its no cheapy so dont expect to just throw it in your book bag (although you probably could).

As for the sound; these effects are pristine! Deadly quiet and the true bypass loops isolate any noisy stomp boxes so your tone is Crystal clear. Not to mention no more cables!!!! And tons of FX routing and in & out options!

The G-System is form and function (you should see this thing on a dark stage) no worries about not being able to see your settings or your tuner from accross the stage!

The big buttons are solid, quiet and easy to access even for someone with big feet like me and they light up bright red when active so no guessing if your FX are engaged before jumping into a lead!

Do Your Homework!

No doubt the unit is built pretty solid but has flimsy buttons to engage the effects. Keep in mind if this goes down then your out of all of your effects.

Over time this unit can become questionable in it's ability to be road worthy based upon my experience with it.

Your general opinion of this product.

A cool all in one unit that I believe is better suited for the home studio musician who can spend hours tweaking it and keeping it safe from the elements. The unit is too complicated for live applications especially when you consider every venue presents different acoustics. It also does not allow you to be creative in a live application playing and adjusting the effects. No. You would have to sit there and pan through every imaginable parameter. Where as with high quality pedals the simple twist of a knob and your creative ear is satisfied on the fly. Keep in my mind that it's not a bad unit but do your homework and research and determine the application you need it for. In my opinion it was disappointing to realize how time consuming this unit can be for effects that were not that impressive. Give yourself more control and remember less is more.

It's digital. Very little warmth. Tends to be very thin no matter how you use it or set it up.

Too thin for me.

looks great but that's about all I can say.

A tank, With unreal sound, the tag is a liitle two

Your general opinion of this product.

Made like a tank.

Best Features??? There is just so much to say. It has everything you want.

It takes some time to set up but it's eazy to use. If you can put down on your feet, you can use this.

Let me say this. Last year I send a order to XXXX and AMS. It was sent the same day and time. AMS had my order at my home before XXXX. Not just by a day or two. But by almost 2 weaks!! Thats why I'm going to stay with AMS. Now the value for the TC. Well I think it is a just a little much. Dont get me wrong... I love the thing, but it's just to much.

The sound is crazy. You will be happy with the sound. From clean, metal, black metal, red neck music, blues jazz. Man what ever you play this will more that do it.

world class sounds,world class price and learning

Your general opinion of this product.

this g system is better made than any effects product on the market , built to last, the switches are perfect.

the sounds are what you would expect from world class gear not one dissapointing sound.

the g system manual needs to be completly rewritten its almost a waste of time. speaking of time you had better have some because this unit takes time to understand and program.

its a bit on the low end for value, I would have felt better picking it up for under a grand

The sounds are the redeeming factor for this unit they can be so satisfying that you can disregard the high price and high learning curve
