HollowState Custom Boutique Amplifiers

I have been building tube amplifier and radio circuits since I was 10 years old. Almost 50 years with an almost compulsive interest in the evolving development of guitar tone have equipped me to serve a growing base of local clients and a few from farther away. I have lived the greater portion of my life here in the San Francisco Area and was there, paying attention in the great days, to Janis Joplin with Big Brother and the Holding Company, The Greatful Dead, Quicksilver Messanger Service, Jefferson Airplane (Starship), Santana, The Doobie Brothers as well as out of town acts like BB and Albert King, Cream, Jimi Hendrix, Frank Zappa and many others.
