Lately, I've been questioning the need for whammy bars... and more controls.
I felt that a more "true" connection to the instrument would be a plain jane affair - think Les Paul Jr., one pup, 2 controls, thats it.

That said, I already had plans to do a minimalist custom guitar, just for kicks, and to explore that area of playing. Some single humbucker thing...
