I'm going to bump this thread again since I don't mind admitting that I am pretty much clueless about amps. The advice on the attenuator was spot on so I am going back to the well.
As I posted above I have a 68 drip edge Super Reverb. I bought it a couple of years before the pandemic. It was in rough cosmetic shape and the original speakers had been replaced. Silverface but before they changed the BF circuit. Had it serviced and liked the tone but not the volume I had to use to get it. Now that I am using it more (thank you attenuator) I really took a look at the speakers. I have two of the yellow label Fender reissues and two of the Celestion G10 Vintage Anniversary.
Now, I know that I hate how those yellow label Fenders sound in just about every other amp I have heard. Don't know anything about the G10's. The amp sounds kind of boomy on the low end and even clean sounds a bit muddy or fart like to me.
My questions are, what do you think about that speaker combination and would it be a terrible idea to yank out the Fenders and throw in a couple of 8 ohm Fat Jimmy C1025's that someone gave me?
