Using your Evans Hydraulic tom batter head is easy. First, make sure your tom drum is clean and in good condition. Then, carefully place the drumhead on the tom, aligning it properly. Start tightening the lugs evenly around the drum, going a little at a time. This helps in getting an even tension across the head and is where the Level 360 Technology really shines, making tuning simple.
When it comes to playing, these heads are great for rock, metal, and funk. You'll notice a sharp attack and a short, deep sound, which is perfect for high - energy music.
As for maintenance, keep your drumhead clean. You can use a soft, dry cloth to wipe off any dust or debris after each use. Avoid getting the drumhead wet, as the oil layer inside can be affected. Also, don't leave your drum in extreme temperatures or humidity, as this can damage the head and affect its tuning. If you're not using the drum for a long time, loosen the lugs slightly to relieve the tension on the head.
