I'm interested in buying a Fender Blues Junior I found on Craigslist, but the posting said this about a hardware problem: "It has a little bit of an attitude sometimes if you like your treble feirce but it's nothing that can't be fixed with a good, easy cleaning. "

I emailed the person and they clarified with this: "It just does that standard thing where it starts to sound a little fuzzy once it passes a 7 on the volume. It's really just some cleaning but you're welcome to try it out and hear for yourself!"

Instantly my BS detector started going off, but then again, I am a cynic. Does this sound like the sort of "standard" thing that could be fixed by a little cleaning or should I search for another amp?
Well, I have a Blues Jr. and yes, it does get fuzzy at high volumes, because it's a tube amp. They naturally distort at high volumes. I don't really know what the guy is talking about, but if I were you, I'd check it out to see if you like it. It really is a great amp.
Tell him take another 100 off because you will have to get it checked out, lol.

Nice amp, normal used price is $300, anything less is a very good deal imo.
