I am looking to replace the MEC electronics in my '95 Thumb. It has gold pickups and the two band pre. I've never been 100% happy with the tone. I find it brittle and lacking in warmth. I really avoid playing the bass through clean hifi amps and use old DR Sunbeams. The MECs are also old and scratchy no matter how often I clean the pots. I am going for the Warwick sound but a warmer and sweeter. I was thinking Barts as I remember them as being smooth in Warwicks. Any suggestions? One caveat: I want to keep the body stock, so a two band and Jazz sized pickups are needed. Thanks in advance!
