I'm a begginer with an Ibanez SR300e. Wish to upgrade to another 4 strings. I like the versatility to get a single coil and full hambucker but something's missing... When I listen to some P bass in particular. I'm not into only jazz sound, so i'm looking toward a PJ config or a humbucker with bypass. Will play mostly 70's prog rock (King Crimson, PF, Genesis), new wave (Police, Tones on Tail and Bauhaus) and Alt 90's rock & grunge (Primus, RHCP, Smashing Pumpkins, RATM). So I guess I wish something polyvalent with vintage and modern tones ? Two groups to choose from (please comment on the best match / groups and specific bass....and why !): Thin necks-semi light body * Ibanez SR650e * Sire P7 (alder or ash ?) * Fender Aerodyne * Sterling SB14 (but where do I rest my thumb ?) Beefier neck-heavier body * G&L Tribute L-2000 * Yamaha BB734a * Sterling Ray34 (but where do I rest my thumb ?) Thanks !
