I'm finding that in my effort to avoid "overdoing the fretless sound" (you know, the fretless players who smear mwah over everything, gliss all over, slide harmonics in every song, etc.) I've been leaning pretty far the other way - heard a playback of myself today and I sound pretty much like I'm playing fretted.
While that leaves me feeling pretty good about my intonation
I also feel like I'm not really utilizing the expressiveness of the instrument as fully as I might.
If you play fretless, how do you find that balance for yourself (do you even try)?
What bassists do you think achieve that balance - who do you hear that you think "yeah, that's niiiice..."??
I find balance in the strings.
I use DR black beauties [40-105]
The round wounds give me the option of having a fretted and very brite sound.
What pickup makes a difference.
When you use the bridge pickup and roll off the tone about half way, you get the electric fretless [ala Tony Franklin]..
If you use the neck pickup, it sounds upright.
Both [humbucking if it's a jazz] you get the full and bright fretted tone if you want it.
I've found that vibratto or the lack there of makes you sound either fretless or fretted too.
It's simple for me. I play in a cover band right now. There's not much choice. Most of the material I play is fretted.
I use a fretless bass on about half of what we do. It's lighter than my 5-string. Plus every now and then, I like to throw in a shake and or a slide and wake up the musicians in the audience. As soon as a guitarist or bassist hears a fretless, they stare. It never fails.
