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.

Fender has used only a handful of different speaker types over the years.

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.

The Blues Junior is a good choice for someone trying to get their first tube amp but it not a professional's amp by any stretch. What about the Blues Junior is so different from the vintage 50's and 60's Fender designs that are so coveted and that so many of my amps are inspired by?

In this article I will delve into the differences in construction and circuit design and how they compare to vintage Fenders.

The G12C is more than three d B lower, which equates to approximately half the loudness of the C/S.

If you want the least volume from your amp, search for a speaker in the style you like with the lowest SPL rating.

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.

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.
