First of all is does anyone else find it impossible to pop on some basses? Would this be due to the gauge level? And is so what is your faveroute gauge level on strings for slap? Also my bass at the moment has Ernie Ball super slinkys and when i first put them on they sounded great but now when i slap on them it just sounds dull and empty, has anyone else had this same problem? And finaly ive heard stainless steal strings are good for slap but i have no idea which brand to go for, could anyone point me in the correct direction. Thanks.
