Bonjour from sunny France,

About 6 months ago I acquired a third hand LP1 in excellent condition and, after several months of using it as bought, have decided that I really do need to make an adjustment to the angle of the grip. My problem is that one of the 4 adjusting screws will not budge! The other 3 are fine but one of the two I need to use is well and truly stuck.

Any suggestions as to how I can unstick it? I am wary of using too much brute force, particularly as the other adjusting screws turn with minimum effort.

Thanks for taking the time to read this post.

Bob
