I read this thread: http://www.talkbass.com/forum/showthread.php?t=178367&highlight=dummy+load But didn't quite get what I was lookign for. Okay, I have a Peavey Firebass 700 (Great Amp BTW, I tried a 700RB and a 1001RB..I prefer mine ) Anyway, I have two 8ohm cabs. The outputs are in parallel so plugging in both my cabs makes a load of 4Ohms. My Firebass puts out 475W@4Ohms. BUT it puts out 700W@2Ohms. Is there anyway I could perhaps add some sorta dummy load so that my amp would be putting out its full 700W? For headroom purposes only. Oh yeah, I'm also curious as to how this would affect the tone, if at all.
