Don’t be surprised if you’re always reading stuff about music on my blogs. I’m not a musician; I only appreciate music when I listen to a good one. Seriously, I’m helping out a friend look for gon bops mixto 2-in-1 cajon at guitar center. I have no idea what it is either, but upon checking one of the websites this morning, it turns out that the accessory looks like a (wooden) box that functions like a drum. I’ve seen this instrument being played by bands. I think one of the websites is selling them at a discounted rate.
