I have a chance to pick up a used Eden WT400 (pre-Wasburn buyout) for $595. It sounds great, looks to be in great condition, and the guy will test the existing 12AX7 tube and also give me a brand new tube for a spare. Is this a good deal? I've wanted an Eden WT400 for some time and never had the cash to get one. But this seems to be a great deal. Anyone else who has one care to offer up any opinions on this amphead? I've done a lot of searches but it seems to come up in huge generic threads that I'd rather not have to spend a week weeding through. Thanks.
