Hmmm I have a few old Bell & Howell tube amps from ancient 16mm film projectors downstairs that sound interesting thru a 4x12. I should send one off to FAS to model. That would be a quirky addition for sure lol. Not sure how you could model the opto-electronic pickup tube (to read film's audio track) though heh. It's kinda neat to modulate that tube with a flashlight when playing; you get weird tremelo/fluttery effects from it...great for 'performance art'
