I had been playing for about 10 years and was in my mid-20's when I got my first fretless. I was inspired to do so as a result of hearing Pino Palladino on David Gilmour's About Face album. It was a sunburst Precision bass someone had assembled from parts: Fender neck w/ unlined fretless rosewood fingerboard, no-name body (probably Hondo or something like that), Hi-A (aka Bartolini) pickup. I think I paid $200.00 for it (late 1980's prices). It sounded great, as I recall. I was playing in a prog-rock band at the time, doing all originals, and used the fretless for a ballad. I took to it fairly easily, and have been playing fretless (as well as fretted) ever since. I can't recall when or why I got rid of that bass, but I remember that I next converted my fretted '78 Stingray to fretless, and then sometime after that I picked up a used Ibanez Musician fretless, then a Fender Jazz fretless, and then over the years had fretlesses by Modulus, Pedulla, Wal, Alembic, Rob Allen, NS Design and, currently, Sire and Ibanez.
