again what ever works.. although I doubt very much a ramp will make you or anybody a better player.. it mite help make it more comfortable or easier to play certain lines but one should learn the proper techniques and not rely on some peace of wood in between your pick ups to be a better player.
Ok let me attempt to analogize this in a way you might understand...
I see you own several basses with frets and dot inlays. Hey man, it's whatever works, your thing and that's cool. People really shouldn't rely on frets and inlays for their playing and correct intonation though, you just need to practice your ear training and technique more. A good player doesn't need fret lines or any of that junk, they just use their ears. It's really just a crutch for people who don't wanna practice and develop a good ear.
Now please don't keep us waiting in suspense to hear you say "It's whatever works", "It's my opinion", and then deride people's technique for using ramps like you have a solid case. I'd also like to add (again) that Jamerson used one finger to pluck and you are in fact a pansy if you EVER use two or three fingers to pluck. Jamerson did it so therefore it must be law.
