I'm having trouble getting a good slap tone. My gear at this point is whats in my sig except the Ashdown got stolen. So, using the Reverend, the GK, and the Avatar, what are good settings or advice for getting a better slap tone? Granted, the Reverend isn't the perfect slap bass, but it does the trick. What do you guys do with your passive Jazzes to get a cool slap tone? Tones I like are old RHCP (Uplift Mofo era), Marcus Miller, and Stu Zender. Thanks for any help.
