In the last 3 years I acquired 2 basses with speed bumps. Took a while to adapt, I've been fretless since 2000.haha, yeah I never cared much for fretsthis bad boy served me well for many years, the neck is crazy slim front-to-back. Not my preference, but for people who like that kind of thing, these MiJ unlined fretless necks are sought after, apparently.
