Re: TC electronics G major
The G-Major uses a simple electrical-short type relay via a 1/4 inch cable in order to switch amp channels along with the presets. Of course your amp needs an auxiliary 1/4 inch switching input to do this but it works fabulousy. If I used a stereo-split y-cable I could also manipulate the amp reverb or the amp solo boost if I wanted to, as it is a double-relay.
Sorry I'm late on this thread...
I'll cut to the chase with the G-Major. simply put for $500 plus the cost of whatever midi controller you choose it will do the job of about $1500 worth of pedals. And I mean GOOD pedals. The quality and control range of the effects themselves surpass about 95% of the floor unit I've tried, owned, or had experience with. Sound preservation is top-notch, I was shocked to hear the difference of how much tone was being sucked up through the 50+ feet of cable and the 7-8 boxes on the floor that i used to run through. I still do use a Wah, EQ, Whammy, and BD2 on the floor just out of personal preference even though the GMajor can be preprogrammed for EQ shifts and Whammy functions with the right midi pedal. The noise gate and the compressor are so good that its hard to tell whether or not they're working... until you turn them off!!
Awesome unit... one of my ex-coworkers at GC has both a G-Major and a G-Force and while he says the capabilities of the G-force outdo the GMajor by a long shot, the sound is not all that far off.
I may never use a pedal for noise gate, compression, chorus, delay, detuning, flange, phase, tremolo, vibrato, or reverb ever again.
