Hi Ken. It is ALMOST the same size, except for maybe a small inch or so. It is a mesa 2x12 3/4-back cab. It is smaller than the recto-cabs, btw. But sounds REALLY nice!!
Here's mine...
Just replaced one of the Randall RM4's with a Mesa Recto Recording Preamp...
Most of my guitars are Ibanez RG's (or a Jem 7DBK I have been really attached to lately), or Peavey Wolfgangs....
All of which are equipped with an EMG 81/85 setup and 3 way switches.
sorry for the crappy pictures..im not a photographer.
From left to right you see an Ernie Ball Music Man John Petrucci Guitar, Furman Power Condition, Dunlop Rack Wah, DBX 266XL Noise Gate, Mesa Boogie Road King Head, Mesa Boogie 4x12 Cab, Mesa Boogie F-50 1x12 Combo Amp, and a Mesa Boogie 2x12 Recto cab, and an Indiana St. Paul guitar I bought and customized and it now rocks.
