A Simple Hand Drum: The CajónTab by Louson Drums
Pittsburgh-based Louson Drums is a fairly new custom drum company. Founded in 2015 by two drummers, Louis and Carson (hence the name Louson), Louson Drums specializes in custom cajón drums and a small hand drum they call the "CajónTab".
Basically a CajónTab is a 10" x 10" by 3" wooden frame with a very thin (about 3mm) "tapa" or playing surface. The drum ships with attached guitar strap buttons and a shoulder strap for upright playing, although it can be played in the lap or even as part of a full drum kit. Louson Drums is targeting not only drummers, but also music therapists, music educators, schools and hand drumming experts in their marketing efforts.
Louson Drums offers customization as well. It might be worth checking them out if you're interested in a new hand drum or cajón.
