I've got a 1954 Gibson J-185 in my shop right now that needs a neck reset. Badly. I assumed this instrument would have a traditional dovetail neck joint, and began to act accordingly. After my first unsuccessful attempt at releasing the neck (no harm done to the instrument, I promise), I discovered that the truss rod appears to from the neck all the way through the heel block, so that it's bolted at both ends. I unbolted it at the heel block, but the neck still doesn't want to release.
Is anyone familiar with this model of guitar, or this type of neck/truss rod setup? I'd like some advice removing the neck before I attempt to proceed.
