Cause they are so awesome and amazing cause if you dont have the money the gas hurts really bad. I got to play a buckeye burl vortex with maple fretboard wide neck 5 string. AMAZING.Clearity and punch. I think i could get it for $2200 but I dont have that. I feel in love with my new curbow and thought I was gas free. I still love my curbow and as much as that vortex but i see one of these in my future.This was my first time playing one and now I understand.
