The nice thing about the LGX-T as opposed to a regular trem synth controller is the LGX-T uses the piezo elements in the bridge for the synth pickup. If you're just using the Roland GK pickup on a pivoting bridge, when you use the trem, the strings move away from the pickup, increasing the chance for glitches. That's why Roland used to quietly recommend a Kahler trem, because the roller-style bridge didn't move the strings away from the pickup when you used it. The G-707 had a similar trem design.
The quality of Godin guitars has really impressed me... the ACS/Multiac guitars are fantastic (i'm seriously wanting an A5 Fretless bass) and some of their older strat and tele-style guitars were on par with guitars like Tom Andersons. For me, i find the LGX is a bit too heavy feeling, and the tone lacks something. But they're fantastic guitars if you like the feel and the tone.
