TUNER FISH LUG LOCKS Keep your drums in tune, no matter how hard you hit ’em. A Tuner Fish Lug Lock is a fish-shaped attachment with a star-shaped cavity in the body that fits over the top of the tuning rod, so that the “tail” rests against the hoop, effectively locking it in place. Using a Tuner Fish Secure Band you can attach them to the rod ensuring that they stay on even on the resonant side. Made from durable polycarbonate, they are extremely hard-wearing and very strong and you can expect your drums to stay in tune even after many performances and hours of intense recording.
