His particular area of expertise is in Fender amps made from about 1960 through 1967.
After reading Teagle and Sprung's excellent Fender amp book, I took them up on their challenge that maybe someday someone will compile enough serial numbers so that Fender amps can be dated that way. I contacted several Fenders collectors and dealers who were kind enough to supply me with data.The entire line of Fender amplifiers from 1955 to 1959 (later for smaller models and Bassman) was uniform in this look—tweed or "airline linen" covering with a maroon with gold stripe woven saran grill cloth.The 1×12 Deluxe-Amp, the 1×15 Pro-Amp and the 3×10 Bandmaster are exceptional in dynamics and tone. I promise the tables will still be there after you finish reading. Okay, I know you’re all just dying to skip ahead to the serial number tables but try to contain your excitement and read through the article first.
