The Jumbo 12" size CajonTab is considerably deeper in tone than the 10" and has more thump and presence. The larger drum creates a greater contrast in tone between the edges and the center.
Choose the 12" if you expect to be performing with other musicians and need more low end, or if you are willing to pick a larger drum in exchange for more resonance and lower pitch. We recommend the 12" Jumbo or a 12" Pro Series drum for people with larger hands.
Here's a video a customer sent us of his unboxing experience after receiving our CajonTab® in the mail:
