Non-Schumacher transformers – It’s been universally accepted that Fender only used Schumacher transformers on amps made in the 1960s and 1970s.
It seems as if everyone has used them at some point, including Elvis, Chuck Berry, Buddy Holly, The Beatles, Rolling Stones, Oasis, The Strokes, Radiohead and White Stripes, to name but a few.
Fender guitar amps have been a constant in rock music, featuring legendary clean tones, lush spring reverbs and, in the case of the newest solid-state models, some of the best modeling and built-in digital effects available today. After all, with so many different models, it may get a bit complicated...
It would be more accurate to say that approx 650 of each of these models were produced in ’60.
Our Buyer’s guide to vintage Fender amps explains in detail how you can date your amp by looking at serial numbers, tube charts, transformer codes, speaker codes, Fender logo, etc.
