For my senior project (which is now required for graduation) I am thinking of building a bass guitar. I searched around and the Carvin kits seem to be the best for my price range, $500. I am thinking of getting the BK4A active/passive bass bolt on kit. The body is alder and the neck is hard rock maple. The options i want to get are Strings fed through body, Black chrome hardware, and Bridge Humbucker & coil tap. This all will cost around $500. The Warmoth(sp?) kits are alot more and need extra body routing for the electronics. I've read good things about Carvin's Basses. What about the kits. $500 seems like a great deal for the bass i will end up with. Any thoughts?
