I choose to replace another push-button on my Polysix yesterday. Since the process of replacing a button is the same for both the Mono/Poly and the Polysix, I figured that I'd take a bunch of pictures and share the process.

If you need to replace any buttons on your Mono/Poly, but didn't know how, maybe this will be helpful to you...

Anyone got any improvements or suggestions
