[quote name='Mike Brooks' post='442349' date='Mar 23 2009, 12:44 PM']Never had a problem with either extension key on my Kubicki's, one is 20 years old, the other 21, maybe yours has been used more. I'm sure Phil has a fix for this if there is a problem, just like he has for most things. Back in the days when the internet was an undiscovered gem to me (92/93) and Newsgroups were the way forward, I contacted Phil as I had a problem with my Fender/Kubicki neck and had read on a newsgroup on The Bottom Line that there were a batch of around 200 Fender Kubickis that were made in 1989 that weren't sealed properly. Lo and behold mine was one of those, rang Phil, he confirmed it, sent the neck off and he overhauled it, new fret job, slimmer neck as per my wishes, turned round in 4-6 weeks.
Splendid chap.

+1 on Phil. I got in touch with the company a couple of times about various things, and Phil replied personally.
