i cant see what a 'pro' can do other than take my money that i have not already tried, fr0sty :) after the neck has settled after the truss rod tweak it seems a bit better. i just don't get the tension issue..... same scale length, similarly adjusted necks, action matched to necks adjustments.... the only difference is the jtv has the trem.... which is tightened (at the claw) to non knife edge vintage style to match my slightly heavier gauge strings (10 tops 11 bottoms) (i did actually block it, but when i took the block out to check it was ok after adjusting, the action of the trem was ok, so i left it open)
