Our band was often playing acoustic music, where a whole drumset would have been inappropriate. First I always asked a friend if I can use his cajon, but later I wanted my own cajon. I really liked the Schlagwerk CP404 and first I wanted exactly the same cajon. I went into the shop and tried different cajons just to see/hear the differences. And then I was playing the CP4005 and I knew this will be my cajon in the future.
Comparing to the CP404 it has much more bass sound and very strong crash tones. Furthermore you can adjust the snare sound with an Allen key, which came with the cajon.
