Unless otherwise requested, Sylvan Temple Cajons feature one board which wraps around all four sides so the wood’s grain flows uninterrupted across the instrument, to make two playing surfaces and a sound hole on the side. One surface has a snare system which tunes on the side of the shell and is designed to be silent when the bass note is struck, unless tuned otherwise. The other playing surface is divided into two tones to play like Congas, with the bass note still active below. The sound hole is lathed to a variety of depths and shapes to facilitate different bass note qualities.
