I'll be moving to New York in a few months (hopefully) and I am trying to find out what equipment I will need in order to get around the city efficiently with a Double Bass. I've heard a lot about the gaines bass wheel and I saw a bunch of them when I visited. Is that the best product? I also want to know what sort of amplification systems are used. I want something that can be carried onto the train along with my axe. It MUST be able to replicate my non-amped tone with a realist PU.
