Re: Pedal "migrates" while drumming. Solution?
Get yourself a non-migrating species... problem solved :)
Just kidding... put some small pieces of rubber material above and below the hoop, it will compensate and secure the pedal more securely and act as a protection for the hoop at the same time, make sure it's some kind of "flexible" rubber, not too hard as it will slip and not too soft as it won't compensate the gap.
Keep On Drumming
