I have an old (maybe early 90's) Samick "custom" bass. It's a five string, but I'm using it from E-C. I'm replacing the pickups w/ EMG's. I already own a 40TW that I want to use in the bridge position. But I don't know if I should put another 40TW in the neck position as well. I thought it may be cood to have 2 volume controls, along w/ the option to have either in dual/single mode. I am aware that most EQ systems will not be able to be added, so I'm thinking of possibly a different pickup. Perhaps the 40P5 for the neck position? Has anybody ever used two 40TW's in one bass? Any suggestions? Thanks.
