Speaker update. I’ve swapped out quite a few speakers (mixed) in the Vibroverb. Tone Tubby San Raphael Eminence 1058 Alessandro GA10-SC64 CTS (vintage ‘67 from a Super Reverb) Jensen C10Q RI My favorite combination right now is the GA10-SC64 and the Jensen C10Q. These two speakers really seem to compliment each other. Thanks for all your suggestions. I’ll keep the amp “as is” for now until both speakers are broken-in.
