The Fender Deluxe amp of the 1950s was a medium-powered unit designed to let guitarists hold their own in a small group. As blues, western swing, Western, and rockabilly bands began getting louder, the overdriven tone of a cranked-up Deluxe found its way on to many live and recorded performances.

At the time, Leo Fender produced amplifiers with the intention of having the amplifier stay clean even at high volumes. The Tweed Deluxe is not known for producing a clean tone at high volumes, and as such, was regarded as being an intermediate amplifier. The saturated tone this amplifier produces at higher volumes is the reason why it is one of the more famous amplifiers Fender ever produced. It is part of the signature tone for many musicians, a few notable examples being Larry Carlton, Don Felder, Billy Gibbons and Neil Young.      

The Deluxe has a 5Y3-GT rectifier, 2 6V6-GT power tubes operating in push-pull mode, and a 12AY7 and a 12AX7 in the preamp. The output is rated at about 15 watts.

This is a lovely vintage 1955 Fender Deluxe amp in fantastic condition. Its tube chart shows EA which means a manufacture date of January 1955. Serial number also indicates 1955.

It has been recently serviced with a few newer capacitors and some dry joints cleaned up. Super clean chassis and pine cabinet is in great shape. The power transformer has been changed to a high quality Mojo Tone 240v unit so no stepdown transformer is needed. The 6V6 and rectifier valves appear to be vintage 60s Philips & Sylvania tubes.

This is a great sounding amp. A lovely tweedy tone, rich in midrange harmonics, and with a soulful breakup at just the right spot. A killer recording amp for sure.

This amp has the famed 5D3 circuit, which is widely regarded as one of the greatest amplifier circuits ever, and has spawned several boutique amp builders chasing the ultimate guitar tone. It is very original, fully functional and sounds fantastic.
