I just picked up a used 12"/6" cab a couple weeks ago. Also has a horn which may or may not get used. Got it for a decent price and was what I was looking for; a cab with a small footprint. I'm still experimenting with it and the Ashdown but so far I like it. I still have a little time to decide if I want a refund but I am likely to keep it. I am terrible at describing tone and sounds, so no help to you there. It packs a punch and is pretty articulate, which is probably not the best for my playing style but maybe it will force me to focus more and improve my playing.
Not as light as today's smaller cabs (it's approx. 45lbs and probably close to 10 years old) but small enough to easily move. Need to scrub up the grill and re-paint it, if I keep it. It's only for home use really because I am not playing out anytime soon so I think I will keep it.
I don't know if I am allowed to even mention who the builder was because he has been (rightly) vilified for business practices here at TB. Just in case I covered part of the badge with a Post-It note. I wouldn't have bought it if the builder was getting the money but buying it used seems okay at this point. Of course feel free to let me know if this purchase makes me a scumbag and I will return it and buy a non-tainted cab.
