Sometime back I had some help to EQ a P-bass. Brill solution, and it's sounded great ever since. A few months back I picked up a USA Fender Jazz (pre-2012). However, I've since struggled to get a good live sound. Using a Markbass 121 and New York cab, the only way I've cut through is to make the Jazz sound like a P - full neck pup, bit of bridge and roll off the tone. I'd like more of a powerful, traditional Jazz bass tone, bit more Geddy/Marcus, etc. Also tried just backing off one pup a little, but that just seems to make the sound very tinny. I'm hoping there's some Markbass and Jazz bass users out there.....whatever your settings, please share!
