So I've ordered all my parts for my custom fretless 4, and I've bought my wood- I await a Carvin NT4 neckthru neck, an EMG MMTW pickup, Sperzel locking tuners, and a Kahler bridge. But in the meantime, I can't for the life of me think of a semi-original (at the least) but non-neckdiving shape. Can anyone help me out with suggestions and ideas for inspiration? The only parameters are these: -An upperhorn is absolutely required for proper suspension (that's why Leo put on the P in the first place, right? ) -The neck only has 12 inches of additional wood for the middle of the body...and after measuring I've found the P-Bass shape, for instance, is 14 inches Thanks in advance!
