If you're looking at this you must know what it is. Excellent condition comes with original box and still has plastic film over the display. It's had little home use and that's why I'm selling her.G-System is a masterpiece. It asks: what if a guitarist could have it all? And then delivers in a package almost too good to be true. The best of the best effects, complete integration and optimization of your gear and total control over your effects and sounds pedal board. And, the added Massimo Mantovani mod essentially optimises the input-design and upgrades a number of components, which results in a super-transparent tone with a very snappy response, added punch and optimal tonal transparency.G-System offers a complete range of guitar effects, but what makes them so different is their sound. We poured all our knowledge but also our hearts and love for music into these sounds and it shows - dual DSP full 96 KHZ / 24 bit conversion and processing meets tone that just raises the hairs on your arm right of the bat.How you play is unique and your challenges are different from any other guitarist. That is why we made G-System like a ball of clay: completely moldable to what you need it to be. Custom button lay-out and assignment, multiple actions with one button press, custom effect routing - you name it, and G-System does what you need to sound your best.G-System has no drive effects. Why? Cos most guitarists have their favourite distortion/overdrive boxes anyway. So Instead of competing with them, we aimed to integrate them seamlessly, and make them part of them system via 4 analog loops and even add 9VDC outputs - life can be so easy.Features:TC's best-of-the-best effects right at your feetUp to 9 effects simultaneouslyFast and smooth preset changes featuring delay spill-overs4 switchable mono-loops for your favorite effect pedals1 additional loop/insert point dedicated for preamps4 x 9V DC outlets powering your effect pedalsUSB connection for software updatesUltimate flexibility as the board can be separated allowing you to place the GFX01 with loops etc. in a 19" rack while leaving the control board on the floorMIDI for control of additional external MIDI unitsConnections for 2 Expression pedals
