When does a 'Partscaster' actually become a 'Partscaster'? Is it like having a baby? A future mother-to-be is either pregnant or she is not. Not just 'a little bit pregnant', as there is no such thing. To my way of thinking, a telecaster is the perfect guitar for modding. It is a modular guitar. Leo made it that way, and a fine job he made of it. However, the happy new owner of a typical tele is often not finished when he buys it new. He, or she, often just can't wait to get it home before the changes begin. Pickups, tuners, or saddles are the first things we tend to 'modify' and so it goes on, ad infinitum. As the proud owner of a number of more than one or two so-called partscasters, from MJT based guitars to a Nachocaster I have often listened to owners of other guitars suggest that what I own, may well indeed be a great sounding guitar, but is not likely to fetch much when I sell it ........and of course they may well be right. But, surely the Fender Supa-Dupa De Luxe that they bought just a month or so ago is no different. When did the Fender S-D De Luxe come with S-D's or Lollars, for instance. The saddles have been changed perhaps, and so it goes on. My opinion is that each guitar, regardless of what the decals say it is, should be judged on it's own individual merits, which include sound, playability and the overall quality of the instrument. I would not hesitate to suggest at this point that there is a very large percentage of "no Partscasters for me" snobs out there, who are actually playing a partscaster or two, unbeknownst to themselves. In theory then, the first equipment change or mod that you make to your guitar that is different to that given in the original spec., and we'll ignore strings or their size here, makes your Fender (S-D De Luxe or Gibson Whatever) a "Partscaster" IMHO.
