if you're lucky to see the roadshow koa gs mini, you better buy it, it's a higher grade koa (it's really visual imo)
a roadshow koa gs mini and koa gs mini should sound similar
a spruce top gs mini will be slightly brighter, and the back and side laminate woods don't make much difference imo
im not in the gs mini fan club, but if i wanted one, i 100% would get the roadshow koa
