Somehow, to me, the concept of a Custom Shop or boutique Telecaster seems like defeating the purpose. The charm of the Tele is it's complete lack of finesse. Ya want a snotty, dirty, scarred, stubborn plank with the attitude of a junkyard dog that treats you with disdain and spends most of your playing time fighting with you. The kind of guitar that spits in your eye but will sit at a table in the pub and have a whisky with you whilst telling you about your shortcomings, even though you paid for all the drinks. And then kicks you in the nuts right before it falls down the stairs and passes out in the rain in the gutter.
If you really must get exotic, buy the bastid a case. But don't use it too often, ya don't want the Tele to get any big ideas about comfort.
