OhBoy - do tell!! So what kind of tone, speakers, what do you like/don't like if you don't mind Kim
Well, it has what I call "Standard Issue" speakers: the Celestion G12T-75. Lots of people don't care for that speaker, but there must be a reason why they're everywhere. Wouldn't be any trouble to swap them for whatever you'd normally prefer, but they are 8 ohms each and therefore should only be replaced with another 8 ohm speaker. Myself? I'll leave them alone simply because I'm used to (and actually like) how G12T-75 speakers sound after they're properly broken in...but I wouldn't discourage others from changing them to something they would personally bond with better.
Tone-wise, it seems every bit of what the MP-2/Microtube would offer through a 2x12 cab except the Quad Tube has a VariCab option (instead of the Wah option the MP-2 has) to make the combo really bulk up to a full 4x12 sound. It's an absolute beast, and is so much louder than I would ever need it to be. Shit you not, my main rhythm patch will shake up every room in my house at less than 12:00 on the Volume knob.
Definitely gig-worthy, but I won't let it leave the house just because it's too darn rare.
I already posted a thread with good pics of it
