Had about an hour to finally get things hooked up and play through the Thorax. Haven't played the bass or vox through it yet but I played guitar through it clean and with a vintage rat driving it. The sweetest fuzz tones I've ever heard. No square wave harsh - just the feeling of the most kick-ass sweater enveloping you. Mind you I don't have any other quality pres to compare it to, but as soon as I have my new Lynx L22 hooked up (playing through a digi 001 right now ) I can't imagine hearing a better tone. Hats off to you. I was vacillating between this and a bunch of other pres. After losing out on a couple of ebay bids I decided to take the plunge and I'm happy I did. You need to get these units in the hands of "pro" reviewers. It's a shame I have only 53rd made (tho' it's cool to be in on a secret).
