Denny Thornbury dropped by The Guitologist lair to demonstrate the vintage 1965 Silvertone Danelectro 1484 Twin Twelve (Jack White) tube amp with his blues harmonica. Microphone is a Turner. He's also using a Stella Vee Squeal Killer http://thesquealkiller.com/
The channels are jumpered and a 12AU7 is being used in V1. Sounds loud and ballsy! See more cool gear at http://guitologist.com
