Hi Jeff, I was just reading some of your responses about Jonny Lang’s Deluxe Reverb amps. I have a 1965 Deluxe Reverb and am trying to figure out if it has a Utah or some other kind of speaker. I also have one of the newer Fender Pro Reverb amps with an effects loop and a silverface Twin Reverb with a volume control. Steve Goldner San Diego Hi Steve, Thanks for your questions. Figuring out which manufacturer’s speaker is in your amp shouldn’t pose a problem unless it’s some aftermarket mystery speaker with no markings.I was thinking of trying a Celestion Gold 50, but I usually only play in my bedroom, and I don't want to increase the amp’s volume. Both amps produce very loud hum whether or not a guitar is plugged in. Or is there some other possible cause you can point me to? Most factory speakers in Fender amplifiers have what is known as an EIA code that specifies their manufacturer.Leo soon realised that amplifiers needed to be sturdy to withstand the life on the road, and decided to build his own, to care for the needs of travelling musicians such as his customers.In 1946, Fender began manufacturing a series of now-legendary amps: the Deluxe, the Professional, the Dual Professional, and the Princeton.They are all very rare today and few have survived.The first amplifiers made in-house by Fender is the Woodie series, built in 1946 through 1948.Looking at the chart below we can see that there was a pretty consistent numbering scheme for the vintage tweed Fender Champs.Champion 800 (green tweed)* 01 to 1000 – 1948-49 Champion 600 5B1 (two tone) 01 to 1300 – 1948-49 1300 to 1700 – 1950 1700 to 5000 – 1951-52 5000 to 5500 – 1953 Champ 5C1, 5D1 (tweed) 5500 to 6600 – 1953 6600 to 8000 – 1954 8000 to 9999 – 1955 Champ 5E1, 5F1 (tweed) C00001 to C00800 – 1955 C00800 to C03100 – 1956 C03100 to C06000 – 1957 C06000 to C08800 – 1958 C08800 to C12500 – 1959 C12500 to C15500 – 1960 C15500 to C16800 – 1961 C17000 to C19000 – 1962 C19000 to C21000 – 1963 C21000 to C23000 – 1964 So we can see that a serial number of C 09556 is pretty close to the lower end for serial numbers for 1959 5F1 tweed Fender Champs.
You also mentioned that you’re looking for a speaker option that decreases the overall volume of your amp.
Leo Fender began building guitar amps before he started manufacturing guitars.
The first of these amps were the K&F models, which were produced between 19.
The original Fender amps were tube-powered and the company also started producing solid-state models in the late 1960s.
Most of the amps were finished in a "gray crinkle" finish.
The finishes were baked in the Kauffman family oven.
They were made in three different sizes, 1×8" (one 8" speaker), 1×10", and 1×15".
Whether it’s a vintage amp or a recent model such as this Fender Pro Reverb, hum can have several causes.
Possible culprits include the preamp tubes, the power tubes, the hum balance resistors, and the power supply caps.
The list of artists who've used a Fender guitar amp live or on record is enormous.
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.
