Jack Read lives two towns over from me. I met him years ago when he was just starting out building basses. I've gone to him for repairs and setups since I met him.
I've played many of his creations (I saw Taustin's bass but didn't play it), including his new J-clones. The reason I never decided to buy one is that I've been playing mostly blues and other rootsy styles and don't need a high-tech bass.
I have been talking to him recently about building me a P bass or maybe a J with P pickups. He's a true custom builder, he will build to your exact spec. For instance, he has had customers bring their basses to him to measure the neck, weigh it, or just LISTEN to it to get an idea for what they want (or don't want). When I told him I would like a thinner neck than his J-clone had, he was willing to look at some basses I have with necks I like.
I think his stuff is a decent value (his prices start around $2000). His attention to detail is excellent and the repair and set up work he has done for me is top notch.
I can understand being hesitant if you can't go over to his shop and see for yourself but Jack will definitely stand behind his work.
