SUMO STOMP GAIN SUMO here. I'm the first owner and was lucky enough to win a lottery at a musical instrument store to get this, but I can't quite handle it with my skills... I'm willing to sell it if anyone is interested. As far as I know, this regular version, along with the limited edition, is no longer being re-released. I'm also considering keeping it and doing some more research, so there's a chance I might suddenly remove the listing. Please be understanding. Operation confirmed. Box has some minor stains.
