ive been playing for four years now, and i feel pretty conifident about taking my bassing to the next level. however, i have an ibanez gsr205, cheap yes, but works good enough for me cuz i dont have much money. i love slapping, and would like to double slap. i can kinda do it on my brothers four string bass, but i cant on my five string because it seems the strings are a little closer together. i cant get my thumb to fit in there right, i was wondering if there is an alternative way to slap. i found that rotating from the wrist and hitting my pinky lower on the string works, but i can switch strings when im doing it so i cant really do any little runs or anything. and the tone isnt the best cuz im slapping so low every other note. id like your advice, or direction to find advice. thank you in advance!
