Guitar techs in my sorry experience rarely play their work to check it out - I suppose they are often ancilliary to the shop and work on a cut of the work that they do and so don't have time to play the instrument. I had a 'pro set up' done that a) choked the strings on any bend on e and b that went over a semitone b) was not intoned anywhere near correctly and c) that had substantial fret rattle on the A and D strings. I had to do it all myself and so I have a guitar with a 15 mile high action on the basis I have no idea what the hell I am doing!Having wired my own pups after one bad fitting experience - all I can say is - its not that difficult if you follow the instructions, so a 'specialist' should get it right first time.
I've got my Ibanez RG570 at Feline right now having a Trilogy fitted in the middle plus a full fret dress and setup.We went for the Trilogy on Tim's advice that it could stand up to the competition of a Warpig bridge and FRED neck. I can't wait to get it back and I'm pretty sure Jonathan has had a little bit of experience fitting them so I should be OK! The Trilogy is replacing a Dimarzio Fast Track which just falls apart under the competition of the Warpig.
