I got some d'darddio pro steels being specially ordered for me down at the local music shop, the question is I dont know whether to put them on my MIM P-bass with Quarter Pounders and a badass bridge or my new Squire fretless Jazz bass. I use them both the same amount right now. I'm learning some reggae on the p-bass and trying to get sort of a John Kahn sort of bass sound, kind of an RNB sound but something that I can also rock out to. I'm just trying to learn the fretless right now and still searching for the right type of string for it, I guess I'm shooting for a Fernando Saunders/David J. tone. What bass would you advise the pro steels for?
