This is a utility item, no one really needs to own one of these, but it's handy every once in a while. This is what makes it a perfect infinite community loaner. I sure wish someone had one to lend out before I bought this. So what is it? Its job is to enable quick switching between two different amps to your speakers. The opposite is possible too. The only rules are, you must be a friend or contributor, you must pay for shipping to you, and you must hold the item until the next person on this thread post that they need it. If you feel you may go MIA or may miss posts here, you should probably send it on to someone who's more of a regular. Probably best to keep it between the US and Canada for now too. To get this going, I'll need a volunteer to hold it until the next person wants it. Reason being, I'll be going overseas very soon and it'll be stupid for me to have to ship it out to the next person from so far away. If anyone is willing to be the first stop, please post here and I'll send it out to you - thanks.
