The preamp is pretty cool. They are no longer made, so it could turn into a collectors item. The guy that made them is associated with Best Bass Gear. I think he worked there because he was able to update the website.

Thanks for being understanding about the USPS screwup. Man, I've shipped easily 200+ things and the first time I've ever had problem - it's with two basses at the same time.
