I purchased both the larger box cajon C68-Z, and the smaller pad in the darker zebra wood.They were exactly what I was looking for. I tend to pull out the smaller pad (the darker of the two offered) more often for a quick rhythm, but the larger box/lap cajon (C68-Z) - no surprise - has a fuller sound. If I had to choose one, it would be the larger. Both have a snare and alternate playing sides. One side engages the snare while the other does not. Both can be played on a table or desk top and both have a tendency to slide off of a lap when playing becomes more active. I sometimes add a no-slip fabric between my lap and the smaller pad. The larger, box/lap comes with a guitar-type strap. You can either sit and secure around your waste to keep the cajon in your lap (this works really well), or you can secure from your neck and stand to play. I have practiced and taught rhythms using my lap or a table/desk top. - both the pad and larger box cajon are superior for practice and teaching rhythm. I would also recommend using both for sound therapy and meditation - if you’re into that sort of thing. Do these have the ultimate high and the ultimate low tones? - noCan you hear a difference between the high and lows?- yes. I have enjoyed using the larger box cajon at a drumming circle. It won’t replace my djembe but it is easier to transport and doesn’t require tuning or head replacements.
