I have a bass that I use as backup to my MM Stingray and Its a very good built and pretty bass but I hate the sound. It just seems as thought the sound is not clear and the tone is muffled especially when playing with the rest of our band at a higher volume. Would you recommend something to me as far as changing the pickuops or anything else that would make this bass good.

Below is what it currently has. I appreciate your help if you can on what I could do to make this bass sound good.
PICK-UPS BY G+B BD-4 DOUBLE COIL X 2
ACTIVE ELECTRONICS
ACTIVE / PASSIVE BY-PASS SWITCH
BRIDGE-BB05
VOLUME AND TONE : DUAL CONCENTRIC POTS
PAN, BASS, MID, TREB
