Founded in the mid-1940s in Fullerton, California by Leo Fender, the legendary amps produced by this company have been heard on countless recordings and are influential on countless other amp makers. In the beginning Fender paired small combo amps with lap steels and electric guitars aimed at student players, but word of the superior tone and build quality quickly spread among professional musicians. In over seventy years of existence, Fender has consistently evolved and innovated its sound from the Tweed era through the Brown and Blackface eras and beyond.
Mercury Magnetics has built a massive collection of ToneClone® Transformers and Chokes for Fender Amps available from all eras of production. Answering the needs of players and amp-builders alike, our extensive catalog of audio transformers is the ultimate resource whether you’re looking to replace a worn-out transformer in a vintage Fender amp or looking to nail a vintage tone in a new amp or amp build. The engineers at Mercury have painstakingly documented every detail and nuance of the best-of-breed vintage transformers and can faithfully produce perfect clones using the same materials and methods used on the originals.
The ToneClone+ Series from Mercury Magnetics adds more utility and options without altering the original tone. Love your amp but want to change your speaker configuration? Mercury’s ToneClone+ Output Transformers give players more impedance options like alternate and multi-tapped secondaries.
