Never had a fretless bass before, but I just ordered one and it comes stock with round wounds on it. Since I don’t like rounds, I will be replacing them with flats. Do flats sound any different on an fretless vs fretted? Are there any sound clips available that will demo any differences? Can anyone tell me what tonal differences I should expect?
In my admittedly limited experience with fretless basses wearing flats? My answer would have to be: if you play the fretless with the same technique you play your fretted bass? No, there's no difference - that I can hear, anyway. But, if you play your fretless bass like most people think you're supposed to play it? Then, Yes; there's a difference. But, it's a difference in the...style? of the tone. The basic tone is the same, with or without frets. Whichever flats you like on a fretted bass? You'll almost certainly like them on a fretless.
Currently, I have 3 lined fretless basses, and 2 of them wear flats. The odd one out, wears Roto TruBass 88M Tape wounds. It's a 32" scale, '93 Fury Anthem, that was built by a mad Canadian genius - by himself, in his basement - to wear tape wounds, and to mimic an upright bass as closely as possible. And, believe me - he succeeded. Especially if you play it like an upright bass. I originally put short scale TI Jazz Flats on it, and the sounds it made were... well, I hope I never hear those noises, ever again. Anyhow...
The other two? One is a '23 Custom Shop G&L Kiloton lined fretless. I quickly removed the rounds it came with, and replaced them with a set of La Bella LTF-4A Low Tension Flats that I'd bought for a different bass - but never used. The other bass is a '24 Schecter Stiletto Studio Fretless that I've had for about 10 days now. It's factory Ernie Ball Group IV Flats are not yet broken in, but I'm pretty sure they won't get replaced any time soon...
Although both the EB Group Flats and the La Bella Low Tension Flats are flats I'd never played before, I can't imagine they'd sound any different on a fretted version of the basses they're on now. Especially if I used the same playing technique on them. But, that's the really nice thing about a fretless bass; you can play it like a fretted bass; or, you can play it like a fretless, with all the "Mwah" and slides you want.
So... yeah; put whatever flats you like on that new fretless - and just... play the snot out of it...
