My vote for all-time Tokyo at night lighting scheme, would be my old Gibson Les Paul bass amp.
Remember that this was the early '70's, so the trippy preamp with different coloured pea bulbs behind each section of the plexiglass faceplate, was exactly what the doctor ordered.
Modern amps?
The Trace is probably the coolest.
The G-K with the lighted knobs is probably the most practical.
My Genz Benz Streamliner 900 with the bright electric blue LED-enhanced tube window has to rate up there, too. Especially if you punch the gain button for an extra LED, and hit it hard enough to get the Peak LED flashing, too...
