I've just started getting back into slap, and I find that my major roadblock was always popping. I was never able to get it to sound good, and then if it did, I could never do it quick. Very aggravating. I'm fair enough on slapping, for now, but my popping is really suffering. I'm using my middle finger on the G string and my index on the A. The way I slap...thumb mostly parallel to the string, like Larry Graham. Anyone got any good tips for getting a good, clean, popping sound? And once I've got that, anyone got any tips for getting my speed up? I'm looking to be able to play some Chili's, but my popping inabilities are getting in the way. Advice? And no Flea flaming please.
