I've had a bunch of AC-30s and always loved them but I found them to be a bit unreliable and TOO LOUD a few years ago , I bought an AC-10 twin and had PaulC do a few tweaks and it's just awesome. I use it all the time I recently saw another one in the Emporium that had full disclosure that it wasn't "quite right" as it stands - but I made an offer and he ultimately accepted so it arrived last week but I didn't wanna plug in and be disappointed - so I waited till I got an old Vox blue speaker ( thanks Moods !! ) and then also loaded it w/ old Telefunken and Mullard tubes and fired it up...... sounds AMAZING.. just super thrilled. the trem side sounds about like a non TB AC-30 treble model ( which I love ) - and gets fatter w/ the amp's tone rolled back the normal side sounds about like a non TB normal and is thicker and fatter it LOVES pedals - trem is awesome - it's dead quiet at idle.... I'm so excited and look at how big it is !! it's only about 5-6" narrower than an AC-30 Interestingly - the cabinet's serial # plate reads "AC-30" so it looks to possibly be an older Vox cab . It's built just like all the 60s AC-30s I've had.. Not sure when the plastic vents came into place but I dunno really care anyways. The larger cab and the 12" blue make my TWO AC-10s different I freakin' LOVE AC-10s !! look at the size of it next to my Tremolux and Marshall in the 1st pic ( compared to my other AC-10 twin in the 2nd pic - next to my Deluxe Reverb ) AC-10 lovers chime in !
