The Blue Angel and Subway Blues are similar but not identical - the Subway is a bit simpler, and doesn't have tube reverb or the 'mojo module', but it's the same general design.
The Rocket is not at all like the Dual Caliber - if anything, it's a bit more like the older Studio 22, but still not very close. The Dual Calibers are true 2-channel amps with separate audio paths, and the EQ on the lead channel is post-distortion (there is also a fixed pre-EQ too), whereas both the Studio and the Rocket are one-channel amps with an extra gain stage switched in at the start (and another one later on, in the Rocket), and the EQ is pre-distortion on both channels... which is why the tone controls don't do much on the lead channel.
