Well, this is how the story goes. Basically, I have a MIA Fender RI '75 Jazz bass. Lately, I've been playing it and the sound doesn't seem quite right for me. At the last show I had, my bass was very low in output and the sound ended up very distorted. I couldnt get the level high enough. I had to borrow a friends MIA P-bass deluxe. That sounded WAY better than my jazz. Another hting besides the output volume is that the sound is really thin. For this band that im using this bass in, (punk/funk/hardcore), I really can't seem to make the sound fit. I was wondering what the best way to solve the problem would be. Here are the things I have chosen as options 1. Change the Pickups 2. Add a Onboard preamp 3. Rout out the neck jazz pickup into a p pickup slot. What would be my best option? Thanks for the help.
