Thanks for the input. My bass is a beat up old Wardair model and the reason it sounds fretless is that the action is way high - strings are like a half inch above the fretboard at the base of the neck. I thought about fixing it but decided I liked it that way, and the intonation was already off when it was first "lent" to me (by a friend who never wanted it back). I grow attached to my craptastic setup.
The song is on Spotify with an E.P. of my singles here. And I will likely upload to Dsound after doing some remixing.
