So, i have the cheaper Squier Vintage Modified Jaguar. Here is a link to it. http://www.musiciansfriend.com/bass...ed-jaguar-electric-bass-guitar-special/h71306 The problem i am having is that when ever i plug into my bass rig setup up, using a acoustic B300H head with a ampeg 250 portabass cab, i get this insane hissing sound when ever i am not playing and sometimes when i am playing. I have had it check out and all of the electronics and wiring in it are fine. Now i always get asked if it is the bass head but the head is brand new i brought 2 weeks ago and the cab is older like 10 years old. Is it possible that it is my cab? it is not any cables because i replaced all the cables last week and still have the same noise. I was also told that the pickups on the bass were meant to do that and if i did not like it just change the pickups. If this is the case what pickups should i change too. I play a little bit of disco and funk. But mainly pop punk/indie music.
do the pickups on your bass look like this:http://www.google.com/imgres?hl=en&...bnh=225&tbnw=224&start=0&ndsp=18&tx=152&ty=73 If so, you need to replace the jazz pickup by the bridge with a 'split coil' because you have a single coil in now. Also, try only playing with the pick up closest to the neck and turn the volume for the back one all the way down...that should stop the hiss too.
are you turning the active EQ knobs all the way up? they should be closer to the center, where that notch in their travel is. otherwise you're boosting all kinds of hiss and racket.
Sounds like a grounding issue. You are grounding it when you play. The bridge is not grounded properly. Check the ground wire that goes to the bridge.
