As the title says, this is a speaker for a guitar amplifier. It measures 7-7.7Ω with a tester, so it's for 8Ω. The cone has a stamped code, so I believe it's the original cone. It's generally in good condition. I was told it was taken from a Fender Hot Rod Deville. Since it's a 12-inch speaker, it's likely from a Deville 212. The wattage isn't clear, but considering the output of a Deville 212 and that it was installed during a Deluxe Reverb repair, I think it's at least 30W. Perfect for replacing speakers in a two-speaker amp or a low-wattage single-speaker amp.
