Okay then I guess we're all aware of the Fender Bajo sexto tele which has a 27' scale length neck and is meant to be tuned in A-A.
Thing is that some guitarplayers either couldn't get used to the wider space between the frets and the general feel of a longer neck or found that the standard tele set up of the bajo didn't suit them, so some have decided to look to other ways to extend the range of the tuning on a tele.
One such guitar that we already discussed is the ESP Stephen Carpenter, which marries a tele shaped body to a seven string neck and active EMG electronics.
This guitar, like the bajo secto has a 27' scale and is tuned A-A but with a low E, making it really more of a short scale bass, something that's also reflected in the placing of the pickups, which are where they would be on a normal bass.
Then there's the BC Rich Robert Conti Signature model.
As far as extended range guitars go, this must be one of the classiest, it has a standard Fender scale length with low B and F# strings added. The guitar has a single neck humbucker, arched top and mahogany body.
Conti playing a Custom BC Rich, which as you can tell was even more ornate than the regular model.
But probably the LEAST tele-like of them all comes from Conklin guitars who made this nine string... *How can I put this nicely?* ...abomination.
This nine string monster has fanned frets, FOUR humbuckers which, if I understand the description rightly, each have their own output.
