Instead, there were approximately 2000 of these chasses produced, which then ended up as one of the three models in question.
It would be more accurate to say that approx 650 of each of these models were produced in ’60.
Their G12C/S speaker is listed as 99.79 d B, while their G12C is listed at 96.10 d B.
The G12C is more than three d B lower, which equates to approximately half the loudness of the C/S.
You should be able to find a number stamped somewhere on the speaker’s frame.
The format may look like this: 220 637 Here the number 220 designates the speaker as a Jensen, and 637 indicates a production date of the 37th week of 1956 or 1966.
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.
If you see any data that is not listed here or notice any errors, for 1970’s and earlier Fender amps, please send us an email and we will update the chart.
Some things are very obvious such as non-original or reconed speakers, non-original transformers, replaced pots, re-tweed, re-tolex, re-grill, etc.
(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.
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).
