My brother recently bought a bass guitar on ebay, but the seller had a 10 day trial period specified on the auction. My brother had played several of the same model so pretty much knew what he wanted. He's still got it :)
But yeah..that's one reason I've never bought a Carvin guitar. Always want to play them first. I was in San Diego recently and went to the Carvin factory store. I decided that I don't care for their 'rapid play' neck, I prefer something more akin to a Louisville Slugger.
