Is there any harm in leaving off the speaker sim/line out board and just use the preamp out or is that part of the mojo?

It definatly shapes the tone, so if you leave the cab sim away prepare for a more sterile sound. Unless you run the amplified signal trough a real cab that is. Either way, it won't sound the same as with the cab sim because your cab will have it's own sound to it.

I dunnow, using preamps that different together doesnt make sense to me when used in a combo. The loudspeaker does a lot for the tone as well. You could use an English sounding speaker with for instance the VOX pre-amp, but I would definatly want an american sounding speaker with the 18watt preamp. Just my 0.02$
