I am extremely interested in purchasing a 4-string Stingray. The problem is...i have not played a huge variety of them...nor do i have the opportunity to. i know there are some serious stingray players on talk bass. most of my basses are all big passive basses...so i would like to get this for my funky type stuff. it seems that the pre-ernie ball stingrays are more saught after and usually much more expensive. why is this? is it really worth the extra cash to go pre-ernie? how do the piezo pickups sound or do you usally just stick to the standard humbucker? what are your opinions on the maple and redwood fretboards on the stingrays? any advice at all on my journey of seeking the perfect stingray? i will most likely be purchasing it on the internet...so i cant play it in person. thank you for your time!
