I've been using Jamstix for a while now, and I'm just a hobbyist, so here are a couple original tracks of late.

Haunted Trailer Park - a campy idea I just had to release as is

The first probably is the Bonzo drum pack, and the second uses the brush set and some Jamcussion shakers. I'm no drummer, but I find I get a rather original sound possibly due to that very reason.
