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.
Let’s take a look at a couple speakers from Warehouse Guitar Speakers (wgs4.com) so I can better explain this.
Jeff Bober is one of the godfathers of the low-wattage amp revolution.
He co-founded and was originally the principal designer for Budda Amplification, though he launched EAST Amplification (eastamplification.com) in 2010.
Warning: All tube amplifiers contain lethal voltages.
Here’s a list of brands along with their EIA codes.
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.
And it’s all produced by a machine that’s ready to go pretty much instantly, with precision cooking available so you don’t burn and dry out the food.
While some boast a seemingly infinite number of whizzy features, your first box to tick is that the machine is robustly made.
