Adam is the first born and the proof of concept. He was created from fairly inexpensive woods acquired from a big box home improvement store. I decided to go that route with my first build because I wanted to prove to myself that I could complete a bass, without wasting a lot of money on materials. Adam came out much better than I could have ever expected. Once he was done, I knew I could complete Eve. Eve is basically Adam, but with much better curves, a lot like the original Adam and Eve. Both are amazing basses, But Adam is the originator, and will remain with its creator. Eve models are available for custom order.
