Unfortunately locking the thread will make the thread fall off the front page of talkbass and decrease the chances of the OP getting a good resolution.
If this was a Fender/Guitar Center/
Musicians Friend Quality Control thread you can bet your life that the thread would not be locked. And btw, humans work at those companies too. Can you imagine the earful that the support departments at those companies get? Day in and day out the folks at Fender produce some of the best guitars ever made yet they are constantly blasted for poor quality control, being an 'evil corporation', etc. etc. on a daily basis. Giving a boutique builder a pass just because they are a smaller business would be a double standard.
Besides the one guy who supposedly talked to Jimmy and paraphrased a few emails, the posts that are actually on talkbass have been pretty civil.
