Hi Guys! I'm very new to this forum and decided to sign up because there was a TON of useful information on here, and the community seems super friendly. Bass players are usually great people anyways, right?! Anyways, to the matter at hand, I own a beautiful Jazz Standard, American Fender Fretless bass. The tone, and feel of this bass is just so beautiful. But I'm wanting to set the string heights correctly and knowing proper use of the, I guess it's called Truss rod. I've tried before to mess with the settings of the bridge and everything, but have a rattle at the head where the strings come over and meet the fret board. The style I mainly play is Jazz, Latin, or whatever my college combo decides to play. I also have a 5 string Jazz Standard (fretted) as well, and would love if any of you knew a good string height for this as well. I use this mainly for funk, or if Chart 9 (Birdland) is called! (Or 11, being Chameleon .) I know that string height is all preference, but I don't want to incorrectly do anything to this bass. I never was taught how to modify certain things on a guitar, so I never knew how! Some of y'all might think I'm crazy for owning such a great bass but not knowing how to operate on it, but I was very lucky and fortunate to get my hands on it . Thank you guys and I'm excited to share my knowledge as well as gain a vast majority of knowledge here on this forum!
