Re: Adjustable bass drum beaters
Why does it matter that the beater shaft be at 12-o'clock when it hits the head? If you just want to "close the gap" why not adjust the beater angle forward so the travel from rest to head is the same as it is from rest to 12-o'clock.
You can, of course, take any old beater and bend the bottom of the shaft forward so that it hits the head as you wish, as well as bend the top of the shaft back so that beater head hits square.
I've used the Sonic Hammer beater before, no complaints. If it does what you need, don't overthink things, and just buy one to try out.
