I teach at a school that has one. We all occasionally use it as means to “upskill” - and it’s not hard to get a piece of scrap plywood.
As to the maple, my other guitars are all rosewood, so I’m after something different. One of the forums dingobass indicates that we can use the staining coat on the fretboard just not the finishing coat, so aesthetically having a consistent color (acacia) with spray on sunburst would be nice.
