Eric,
Maybe not as much boom as if it was a neck-through, but it should be noticeably extended (and heavier) with the ebony.
I didn't know I could get wide lams in a set-neck, otherwise I'd have done it myself.
Regardless, Orions are great! I have two nearly identical ones. The body style is very comfortable and fairly light, and the midrange punch is awesome!
If it's not too late, you might wanna consider EMW electronics...it adds a filter and q switch to the stock master vol, pan, bass/treble controls and makes the instrument infinitely more versatile for not that much more money.
Just my two cents,
Cheers,
Kevin
