I really love the clean sounds from this amp and want to maximize headroom. I know that 30 watts only gives you so much headroom, but I also know the volume knob goes a longer way with a louder speaker. I have a WGS Reaper in there now and it sounds really nice, but WGS speakers seem to be lower efficiency than their Celestion counterparts, though measurements can vary by manufacturer. I'm thinking about a Scumback 65 Watt H, or maybe a 65 Watt Scumnico. Alternatively maybe bringing out the big guns and getting an EVM12L, or WGS 12L. Any ideas?
