Il try to explain one sider and short box a one sider is a short box that works on one side when you run a one sider it closes up all the way to the other soundboard that is not round on the top like a regular short box because of that the box/sound chamber sounds different the lid on one sider is curved of center to get different stroke longer one I think one is one of the best designs my hats off to Mr Lynch. hope this was some help ..not a trick question is it ? *lol*i'm no writer but i can make turkey call .
I appreciate your response and it was certainly not a trick question.

I only have limited experience playing one siders at shows and such. In my simple assessment, they run and sound pretty similar to short boxes, but I wanted some "expert" opinions. Your points about the lid having different angles and the design perhaps inherently offering a longer stroke are well received.
Another way to ask may be what is unique and worthy about a one-sider design, compared to short boxes? Can either do anything differently than the other?
I know there are lots of master callmakers and gurus on here that may be willing to shed some light before I jump in....
