thanks.. i did call today and talked about my bass.. he is a nice guy. he said i should bring it in before he can say whether my setup would be more expensive than what he quoted on the phone or not (i wasnt too far off in my guess).. and then i can decide whether i want to go through with it.. well, looks like my 506 is going to cost me a LOT

just to be able to tap easily on it

maybe i will try to do some myself before giving up and paying so much
thanks guys
