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. It’s been over a year since Part 2 of this series was printed, but that’s because I’ve been busy collecting data.
Early silver face amps: Part 2 went into this topic in some detail, but since that article was printed, I have been asked a of questions about this subject.
(I’ve also included a few others brands you might encounter as aftermarket installations.) This should help you identify your speaker.
You also mentioned that you’re looking for a speaker option that decreases the overall volume of your amp.
Some things are very obvious such as non-original or reconed speakers, non-original transformers, replaced pots, re-tweed, re-tolex, re-grill, etc.
and these changes are often disclosed and of a non-malicious nature.
