I just recently got my new stingray 5, and was wonder when it was built. The s/n is E33705. Also to let you know that I also own five other basses, which are a Bossa, Warwick,Kubicki, Modulus, Ken Smith, and now my new edition which is actually my 3rd Stingray that I've owned, the other two I sold to get my Ken Smith. In my opinion the stingray ranks as high as my other basses in terms of quaility and value. Keep up the good work!
