Howdy, T.O.:
I wouldn't throw good money after bad on that cr@p-caster...
-It apparently doesn't suit you as it is...
So consider selling it 'as is', as a stock 'roland-ready' strat...
-then apply yer funds to a new GK-either the 'facehugger', or the built in kit...(they cost the same, at least here in DK...but ye'll have to install it, or have it done...)
-and adapt a guitar that already performs...
Trems are less than ideal for the synths- they stream bending info, and hog the synths already taxed cpu-hardtails track faster-Also, many trems physically raise and lower the relative distance of the strings to the hex pickup, in their diving/pulling sweep, and those GK's want to be as close as possible for the best performance-those original strat trems are the worst!-
Roller trems like the old Kahler stay at a consistent height if you gotta have one...
-If you have an old sleeper you can spare for the project, I think you will be glad for it's familiarity, and wind up with a "real" instrument that frees your conscience for expressing yer vivid synth-scapes...Vamp ON !
