Papernoise Concertodrone (Casio SK-1)

promopic-header

The Concertodrone is a circuit-bent Casio SK-1, which I’ve built years ago. It’s called Concertodrone because the first version I did used a Realistic Concertmate 500 (The Radio Shack rebranding of the SK-1). For quite some time people kept asking me to share details about how I made this, so here they are (see below)!

But first a little video to showcase what the instrument sounds like…

Build Docs

I’ve documented all the bends and additions to this SK-1 in a handy PDF document, which you can download here:
