Serratus from the Bare Knuckle forum said this about the Emerald:

“The Emerald is definitely less low-mid focused, with smoother and more compressed upper mids and highs. Still plenty of bottom end too, although it's definitely more high and upper mid frequency focused than the HD. Split harmonics are very easy to get, and it's a very warm sound with no harshness...Overall I couldn’t be happier!”
