Here's my imitation of a fretless: http://herculeaneffort.adventuredevelopers.com/imitationfretless.mp3 I have no effects applied, this is a direct-in recording. I, however, am using a little gadget that I made that attaches to the neck of my bass to imitate the mwah of a fretless. It's not near perfection, but this is a little sample, anyways. Why, you might ask? I'm can't afford another bass, and I love that fretless sound.
