Nothing impressive. Good it comes with a key becouse a thicker key can not fit all bolts, particularly on the beater adjustment. Simple pedal which I like, well done, good manufacture,not too heavy and easy to work with it. Long board not mine choice, the movement is oily and not defined. Good beaters, light and nice coat. If you think they are short pull up the bass drum a bit. The fixed spring nut is stable and good idea by TAMA, BUT really difficult to adjust till you get your tension, because you must remove the pedal and pull the spring hard and painfull 1000 times, but you can turn in other side or change it with the upper nut which is more practical in deed. Uper nut is usless and hinder if you want a tight spring. You can adjust the length of the chain, but you have to cut it .Generally any cheap pedal does the same. Not mine pedal.
