I got a question for you guys...can enyone tell me what kind of effect Jaco uses playing "Slang"....you know that repeating thingy....is it called ping-pong effect or something? Yeah...um...I would also like to know what do you thing about that song.
He used a function on an old recording machine, to record that phrase and loop it back. modern day "phrase samplers" do this. you should start by doing a search here. check out the boomerang phrase sampler the boss rc-20 and the digitech BNX3 there are a couple others out there as well.
