So RMC returned my email along with a few pictures of their pickups. I originally was going to go for the Wilkinson piezo saddles, but then I saw these too and now I'm thinking of going with them instead. They also send me a price list and it'll at least be +$300US to get a set along with an active buffer/blender/feedback elimination preamp board. So I'm still thinking about it on that one. Someone also made a comment about the quality of RMC piezo pickups on his Brian Moore bass and he said that they're so good, one can just use piezo only (along with their special 3 band preamp) and be totally happy with the tonal availability. Now the though of that is alwasy creeping in my mind. Although I knew I shouldn't because I never have first hand experience to validate that comment, and I already told Allparts to order me these Bart X4 narrow soapbars. But on the other hand, the bass will look so badass with only these piezo bridge with no pickups.
