Re: The 2 x 12: How do like it served? Combo, Combo+Extension, or Head+Cab.
I voted fot the early Boogie...112 combo plus a Thiele. I've used this for years, and I think it is the most versatile.
But....
I have Maverick and SUNN 212 combos. I have a pair of older Mesa Half-Back 412 cabs. I have an old Mesa Half-Back 212, and a newer Horizontal Recto 212 cab. I like to use this cab with the Maverick 212 for a low-power halfstack. I have a pair of the Mesa 112 EVM Thiele cabs.
I have two heads. One is my first Mesa, a 200-watt Mark III Coliseum head for the 412s. This is just a glorious rig to play through, if I can get the MV up around 3 on the dial.
And then there is my little Mark V:25 mini-stack; head with the slant and straight 112 Mini Recto cabs...like the one picrured above, but in basic black. This is a fun little amp to play!
Overall, I think the 112 combo plus 112 extension is the most flexible rig, but honestly my house looks like I voted, "All Of The Above". I am definitely amp rich at the moment.
The pictures of the old Twins made me think back to the '70s. Two of the most popular club amps were the Fender Super Six Reverb and the Quad Reverb. I knew a guy that had a Quad with JBLs...probably close to 200 lbs. I had an old Acoustic Control 150 head and 610 cab; it was a lightweight compared to the Super Six.
I like heads and cabs, but sometimes...all you need is a combo. Flexibility.
