Well, "made", anyways. I took my old P bass and put a Mighty Mite fretless neck on it, along with some new machine heads. Took a little bit of work to get the neck in the pocket, but it plays really well now. I'm quite pleased.
nice!
this is a bit of a weird but what is that rubber thingy under the end of the fretboard for?
It's a tug bar. You use it as a finger anchor so you can play with your thumb. I threw it on to vintage-ize it. I'll use it once in a while when my fingers are cold, but it's mostly for looks and that old-school vibe.
I made a fretless.
