i played a rock bar gig last night and left my two 1x12 cabs at home as there was an 8x10 provided, also FOH support. I took my 650 watt D class head along in case the PF50T didn't cut it, after all it's only 50 watts. Dang! With the gain on 12 o'clock I had the master on 10 o'clock and it pumped! Plenty of headroom, and the sound guy loved the transformer DI. Happy man here.
