Adriaan, if you ever consider going for it and need advice, as long as I am alive and kicking, I'll help.
Olieoliver, great to read what you said, I agree, slap is NO funk, slap is slap, period. Some guys slap very well, yet, they don't have the groove! I am NOT crazy about slap, although it depends who plays, it can sound nice (Louis Johnson). I prefer finger style, with occasional slap/pops, I don't have names to give really, I just listen to various tracks on the radio, and sometimes I spot some nice groovy bass lines... There many bass player out there, they don't have big name, yet, they can groove/funk big time. I like the old James Jamerson for example, it's not too Funky but I like it. So, for me, Funk is the groove, the syncopation, the vibe, the style, the missing notes, the crazy chromatic moves... Long live the Funk!
