Wanted to add a real cool thing;
Recorded a fretless a while ago, and it seemed like the sound was missing something. I wanted to go for a more acoustic sound, but without an acoustic bass:
We took the electric signal again, but this time close-miked the (electric) bass near the neck, while standing in a hallway. This produced an awesome sound! People who heard the recording thought it was a double bass, which was kinda the idea. This was a singer-songwriter recording, which 'needed' sort of an electric-acoustic earthy sound. Mission accomplished, I guess.
With a bit of creativity and unconventional thinking you might get some great results.
