Just got a new MIM J Bass for $279. Last year's model they said. I think it was a mispricing. I want to do a minor upgrade as in pickups, rewiring, etc. Any ideas on this? Should I drop in some DiMarzio's or Fender upgrades, rewire everything and call it a day? As my user name would suggest, this is a hobby, so I'm not going for the absolute killer esoteric tone. Just something clean without the hum. Thanks!
