Hi Steffan; of all the C models that have been threaded here ... there ... and everywhere ... Scratch's was in the worst shape; part of the neck block system had been ruined by over-tightening bolts ... but that's on wrench-boy ... not the block. It may have had a crappy neck angle too but the neck, besides being warped or twisted, had a ski-slope bumpity bump. As FNG pointed out in the Trainwreck thread, there's reason to believe at least some of the problems were with the necks - like Scratch's - and not really a problem with the block.
Jeff's guitar's had a bad neck angle and some fretboard issues ... not block issues; his luthier got hung up about the amount of effort needed to get the neck off because of the finish running into the neck/body joint; once he got it off, it went back on and got straightened out:
read here what Jeff said.
If you buy the guitar and it isn't perfect out of the box, you have some exposure on paying a luthifier to at least inspect it and quote a cost to fix ... and that has to be done within the 14-day window; down here at the go-to shop, 14-21 days is about their backlog. It would change things if you have a 'walk-in' guy who can look at it. Of the 10-12 reported C model buys here, Scratch's stands out as the most hosed-up ... but you'd have to ask Frono whether that's statistically significant :wink:
Good luck!
