I, like many other Maiden-obsessed fans, have a 250 RL. I love love love that amp, but what makes it so darn special is the built-in effects. I don't believe that its preamp is anything too interesting, other than it sounds pretty darn ok (unique like a rockman). The EQ section is weird (not anything like a tube amp) but very useful. I am just not sure that a model of this amp would be all that great, and Cliff does not seem to care to model solid-state stuff. The amp is cool, but not very dynamic, and without the effects it sounds like a passable solid state amp. However, if they would just model the chorus, then I would be thrilled.
