Are all models cab sim out?

There is no cab simulated output on:

MicroPro (Gen 1 or Mach 2), Steelaire, 101 Mini Head or Reverb, Bass Block 800 or 802, Tone Bock 200,201, Pro Block 200, OverDrive 200. 

The outputs on these models takes a tap off of the speaker output and pads it down to line level. 

The MicroBlock 45 also does not have cab simulated out, but it has no speaker tap as the other models do.
