He co-founded and was originally the principal designer for Budda Amplification, though he launched EAST Amplification (eastamplification.com) in 2010.
The SPL rating specifies how loud a speaker is at a distance of one meter when driven by one watt. I don’t know what speaker is in your amp, and even if I did, its specs might not be available.
That’s probably a moot point, though—experience tells me that most original speakers in amps of that age are substantially fatigued and generally sound very weak. It's a great-sounding speaker, but with a sensitivity rating of 100 d B, it’s relatively efficient and would probably be pretty loud in that amp.
Possible culprits include the preamp tubes, the power tubes, the hum balance resistors, and the power supply caps.
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.
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...
so let's go back a bit to have a look at the history of Fender amps, at some famous users, and find out which are the best Fender amps you can find today!
You also mentioned that you’re looking for a speaker option that decreases the overall volume of your amp.
You need a speaker with a lower audio output, so you should consider the spec known as SPL, or sound pressure level (sometimes called sensitivity).
If you are unsure of this procedure, consult your local amp tech.
Jeff Bober is one of the godfathers of the low-wattage amp revolution.
The Fender musical revolution started before the birth of rock music, just after the end of WW2.
