Millenium CP-777 Cajon Pedal

intellectually speaking, I'm not Neil Peart or Mike Mangini and my favourite drummer is obviously 'Animal' from the Muppets but I can usually put together most bits of drum hardware without too much difficulty. There are 5 parts to this cajon pedal; all carefully packaged in one box. I had a quick scan over the (colour photographed, 3 step) instructions and started to put the pedal together with good initial results. I was able to construct it without too much difficulty but I ran into 2 issues - I couldn't get the beater to move and then when I figured that bit out, it was not comfortable to play. The solution to both was in the instructions but it wasn't written ; it was in the pictures.
If you have the pedal end of the hinged cardan shaft at too extreme an angle it can't rotate and therefore the beater won't move. Maybe this should be mentioned in the instructions? With this problem resolved the playing position became even more uncomfortable until I went back to the pictures again. I am used to playing cajon with my hands or with brushes of various sorts and I sit square & straight with the resonant head to the front and the sound hole at the back. When you add a pedal to the mix you need to think outside the box! The picture in the instructions shows the cajon rotated slightly. You are sitting astride the corner - one leg to the front and one leg to the side. Maybe this also should be specified in writing in the instructions?
This cajon pedal is incredibly good value and feels solid and well constructed. It's quality is well above its price tag. Well done Thomann. It has a smooth action and the beater creates a decent sound (although it might produce a deeper tone if the beater rod was shorter and therefore able to hit lower down on the head?)
I would have no hesitation in recommending it but please read the instructions, look at the pictures carefully and think outside of the box!
