I just started learning some slap chops from my instructor. I noticed a few things. 1. I feel set up has a lot to do with how effective you can slap 2. String spacing on your bass should be fairly wide My bass has narrow string spacing and if I set it up with low action I get too mych fret buzz, I raise it, it makes it difficult to slap without hitting the string very hard. ARRRRRGGGGG so what do I do? I think I can releave the action on my bass so I can lower the action a bit but is it still possible to slap with narrow string spacing effectivey? I will ask my instructor the same question but I thought I would check with you guys....how frustrating!
