when I try to slap I get more than just the "normal" sound. I get a metallic twang. It sounds like the string is hitting metal or something. After watching A ton of videos, I feel that I'm slapping right. I think it may be in the setup. I'm new when it comes to playing bass and bass setup. I recently got a warwick corvette std 5 string bass. It wasn't played in over a year and the strings were terrible. I went to my local GC and asked what strings were best for playing a variety of music and he suggest Ernie Ball reg. slinky. I watched watched the warwick videos on how to do setups and feel it went well. Strings were matching the fret board radius, I can fit a business card nicely through the first fret on the b and g strings. I did go with a 3mm and 2.5mm height rather than the suggested 2.5/2. I don't hear fret buzzing or anything when I play normal (unless I hit the fret wrong).
