well I am no expert on amps and speakers, and I know lower watt speakers are used when that tweedy break up is desired...but as a Silverface Fender Twin Reverb is not tweedy, and is 100 watts of clean/headroom...i'm not sure how you can run two 30-watt speakers which only total 60 watts, in a 100 watt amp? a V-12 30 is 30 watts, yes?? that sounds like a recepie for failure. u could have two 200 watt speakers in that thing! (would
sound like the creambacks, just a lot more headroom/volume available). anyway, glad u got it sorted! prefer silverface Fenders myself
