This glorious spinning, twirling plexiglass mechanical monster is the Scanner from Analog Outfitters, who build beautiful amps from recycled Hammond Organs. This time around they're repurposing Hammond vibrato units and mating them to a spring reverb. The unit is expression pedal controllable (stupidly fun!) but also has line and XLR outs so you can use it as outboard gear in a studio. At $1,599 it's not cheap but MAN it sounds fantastic.
