davekoch said:I've seen a few posts indicating the ThunderFunk amps are under-rated. That is, they seem to put out more power than they're rated at. (They're just louder, given the same rating.) For guitars anyway, I've always believed a "Mesa Boogie" watt is louder than a "Peavey" watt. I have an SWR SM400 (bridged: 420w @ 4-ohms/400w @ 8-ohms). How accurately are the SWR amps rated (under, over, close, etc.) - compared to a ThunderFunk 420? Anyone A/B'd a TF420 (I'm asssuming it's about 420w) to an SWR SM400? Would the SM400 have enough power to get the "best" out of the 1210/1212s? Better suited with the Regulars or Lights (lower rating)? Which would you choose? Or would this be a bad or less-than-adequate combination? Anyone?
Is matching up the SM400 to a 121X just a bad idea? Are the old SWR amp any "better" or differenct than the newer ones? Anything akin to the Fender "vintage voodoo" thing? My hit-or-miss (mostly miss) experience with the old Fender basses is just that - they're old. I've come to realize that just because it's old doesn't mean it's better.

I the SWR and the older Thunderfunk 420, the Thunderfunk is easily louder!

about my sound since the magical day that my own Acoustic 360 pre-amp head with two Acoustic 361 powered cabinets were delivered in 1970...in fact,the Schro 410 really reminds me of the "Acoustic sound" with 4 ten inch speakers, instead of the reverse mounted 18" Cerwin Vega, the way the Schro's rear-angled speakers cut thru the mix,the cab's overall volume,built like a tank,but even better tone
(IMHO)...no GAS here...
