That is good to know. Would it still raise the volume that much if I had the AD20 totally turned down? Are attenuators something I could pick up at a place like Sam Ash (I'm in NYC and it's a block from where I work-- they seem to have a lot of this kind of stuff. Also, this isn't going to be the only time I'll patch off of this guy, so it would be worth it to figure out a long term solution.
