I am looking for a power amp for my new fm3. I play in a melodic death metal band and use a 16ohm orange 2x12. The other guitarist uses a 120 watt 5150 with a 4x12. I was looking at the Seymour Duncan power stage 700 -200 and the peavy iprs 2000. Any suggestions would be great. I know with the cab being 16ohm that cuts my wattage down by a lot. I currently use a 5150 III 50 watt live with this cab.
