16 ohms? I got one of those Carvin TS100 amps it is stereo at 4, 8, or 16 ohms also got the 6l6 upgrade & I can't wait to get another one, I run a 4-12 400 watts cab at 4 ohms it can get very loud and without distorting the speakers, an all around good clean sound, which is why I hope they incorporate being able to control the amp bypass volume by assigning it to the expression peddle on the next firmware update, that's my clean channel, so go to ideascale and vote it up!!
