How do I get that warm sound for Jazz on an electric like on the big double basses? I am thinking flatwound or nylon strings but dont know...
Is it a Piezo pickup or magnetic? I ask because I have a great string reccomendation for a piezo that simply won't work with magnetic pickups. If you're playing with magnetic pickups I suggest you try nickel flatwounds. Since I represent a MFG, I'm not posting on what's the "best", besides there's never a shortage of opinions ;-)
Nickel flats and then adjust how you pluck the strings. Here's a good pointer: http://archive.bassplayer.com/trenches/thumb.shtml
labella flatwounds are nice they dont hurt your fingers. I have them on my basses. if you like your frets, some musicmans that are fretless have inlays where the frets are. Im pretty sure other companies have the inlays too, but all i know of is the musicmans with the inlays.
The most string-bassish electric strings I have tried are Fender 9050 flatwounds. Very warm and thumpy. I have tried LaBella flats, LaBella tapewounds (#2 in my book for the URB sound), Ernie Ball flats, D'Addario Chromes, Roto 77's and others, and while they're all fine strings, the Fenders are really close to an URB-ish sound.
I heard a guy playing some La Bella tapewounds from Carvin.com and they sounded very good, and rather double bass-like to me, but with a bit more edge. The strings were 2 years old too. If I had a bass that I exclusively used for jazz/blues I'd have those strings on it.
the inlays he is talking about are lines where the frets would be. This way ull have a easier time placing ur fingers at the right spots on the next without having frets.
