This is"'lil Pony," the prototype Rev Je Combo.
There all sorts of stuff written on the chassis, but it's 'lil Pony because Tony used the proceeds to buy a Mustang... his writing is all over it.
She's 20w of power thru an Eminence Governor (as I recall.. heavy magnet).
Basically, this early version was the "brown sound" of his original circuit that gets hotter when you engage the effects loop.
Great little tube amp.
