This is a side-hole type cajon that can be played on both sides, with a resonant surface and a bongo-style surface. It has a wider width than a typical cajon, and the low frequencies resonate well. This is an OEM product with the SOL PERCUSSION logo. It has good low frequencies and the bongo surface also sounds good. https://reverb.com/item/281693-sol-percussion-cj-dosv-00-dos-voces-two-voices-cajon-with-bag https://www.youtube.com/watch?v=NtnT3VpY-XQ https://www.youtube.com/watch?v=y9cIdILMuYI
