Hi, Im a LGXT user and i play fusion.
I been using 0.11 for a couple of months couse i was searching a better sound on the gr55 and the guitar sound itself (the PU are ideal for heavy gauges couse they can absorb! the whole rich and complex tone that the strings give.... you now, seymour jazz III is a great humbucking).
For me, was a great change couse i have my guitar setting for a 0.10 gauge and the bridge was set up in total contact with the wood and when i changed the strings , my tremolo bridge due to the tension, now its set up like a flotating brigde giving me more game and stability in tunning but without changing significantly the action (im in the medium/high range of action). But the real deal is the sound so, i can say that now, i can play with a tridimensional control of the sound couse the range of tone from my new strings is huge and i can control the texture and body of the sound with minimum changes in the way i use my fingers o pick.
In other words, 0.11 give me a better and richier range of sounds tan the 0.10 and the godin LGXT fit perfectly with the strings even without effects, amps sims, etc. And with the gr55 i have now less gost notes couse the definition of the sound.
