So I was rehearsing last night and my keyboardist brought his GK 1x12 200 watt combo for me to use instead of lugging my 350 watt ampeg bh115hp. Long story short before I plugged in I was concerned that I would be under powered seeing the diminutive stature of his smaller GK, but damn, it not only was louder, but just way thicker and deep than my ampeg. What in the world is going on here? It's 150 watts less but sounds twice as good...?
