Seen a few of these in pretty good condition going cheap on eBay with no reserve. I've looked around and from what I can gather they weren't exactly Fender's finest moment but I haven't really seen any explanation as to why they aren't considered to be that great. I was wondering if anyone here has any experience with them and if I could get some opinions on how good or bad they really are and, importantly, why. The main reason for this is because, while I'm not exactly actively looking for a new amp, I do want to get a replacement for my venerable little Kustom practice amp at some point and, well, these are genuine Fender valve amps and they're certainly going cheap. Thanks!
