I'd say this is the Black Dog to a T. Smoother top end, mids that feel very much like the Mules' but more so, not quite as upper-mid focused as the Rebel Yell.
Definitely not the Emerald; the bridge is much tamer in the mids than even the Mule. Its thing is harmonic richness and low-end control, and if you don't like the presence/high end on the Mule, that's still very much part of the Emerald's character.
