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 seem to use it properly with my skills... If anyone is interested, I'll sell it. 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. The box has some minor stains.
