I'm going to jump in and defend John at Bravewood once more! I have met with him 3 times in person, and swapped emails and phone calls many times. He has always been a pleasure to work with, even though my first guitar is an HSS modified Strat (which I thought he might not want to do). The problem he has had (like many other custom builders I suspect), are time wasters and also mind changers. He is a one man company and he makes everything himself from scratch (including some metal parts), and does all the spraying and finishing. He doesn't list his phone number anymore because of the need to get on with things without interuption.
With anything that you are having built for you, it is important to decide exactly what you want before you start to get it made. Once the job starts there are many factors that will cause frustration to the maker and extra expense to change. Also, you have to be prepared to wait, and I think this is where the problem comes in. My first guitar took about 14 months to finish. My Jazz bass is now pushing 17 months (but to be fair on this I told him that I was not in a hurry and so he wanted to let the finish harden and age more before 'relicing' it). I am currently having 2 other guitars done (a replica of my 57 strat and a rebuild of my 61). I dropped off the parts for the 61 and the neck for the 57, in April and then came back 3 days later to collect the 57 neck (he was just measuring and profiling it). I haven't checked on the progress of these since. I worked out what I wanted for the 57, and went through a couple of options with him, and was lucky enough to spot a body that was perfect that he was already working on. I'll probably drop him an email in the next week or two, just to say hi and see how things are going. I will not be back in the UK until October and John knows this, so that is when I will collect the bass. If anything else is ready it will be a plus, but it is not a problem if they aren't. If I was younger or hadn't had a lot of things made for me that took a long time, I would get frustrated with the wait, however once you play the guitar, then you can see why he needs the time.
