I think they are having problems getting the swamp ash wood so now don't really specify what woods they are using. The lighter Specials are nice but I wouldn't necessarily turn down a 9 pounder if you loved the way it looks and sounds unless you have back problems. I sit and play ☺. Like I said, I think weight is a factor in the sound.
I like a little weight too. Mine is 8.9 pounds which I think is nice for a 5 string.
Still much lighter than any other 5 string stingray I've tried!
