Yamaha GW-50 - One of the rarest and most interesting multi effects pedals

The Yamaha GW-50 is about the rarest multi effects pedal I've used. In fact this is the only one I've ever seen. I the video I suggest it's late 90's but now I'm thinking early 90's or maybe even late 80's. It has some extensive capabilities though, and as a practice unit it's got a lot to offer. As a performance unit ...not really.
