Episode 158: Chris Benson of Benson amps and Bryan Sours of Soursound transformers make their long-awaited returns to the Truth About Vintage Amps. Why? They want to tell us all about the logging truck of an amp they are currently building, a 700-watt(!) all-tube beast dubbed Babylon! The Babylon will feature 14 KT88 tubes, 16 total speakers, three knobs, and two power cords. It's literally the most powerful tube amp they could make without requiring a dryer outlet.

Check our Instagram for a sneak peek at the creation.

Deep cuts: Bryan's first appearance on our show can be found here (it's pretty epic) and Chris originally appeared on our 30th episode.
