My 55-01 arrived in the mail yesterday and it's pretty cool, but I'm not at all a fan of the MK-1's. Granted, this is a beater bass, a stand in to preserve the looks of my 55-94, so I'm not looking to spend a bunch of cash on it, but I do want to improve the tone. I also have a Repob with EMG BQC preamp, 40P/J pups and I absolutely love to tone -- it has a hi-fy warmish tone that absolutely kills. If I could come close to that while not routing the body of the 55-01, I'd be in heaven. As much as I love my 55-94, the tone is a bit sterile to my ears. So, will swapping the preamp or the pups first give me the most bang for the buck. And, any idea what pup/preamp combo will come close to the above EMG setup?
