Questions frequently asked
What is the diameter of the Drum O’s HC4 ring?
The ring has a diameter of 4 inches and a chrome finish, indicated in gray in the specifications.
How to install a reinforcement ring on a bass drumhead?
The installation requires tracing the inner contour and then cutting the drumhead. The male part is glued on the outer side after cleaning with the provided alcohol pad. The female part is then clipped from the other side, possibly using a flat screwdriver.
Does the Bass Drum O's Original facilitate the placement of an internal mic?
The hole created in the resonant head makes it easier to place a microphone inside the bass drum.
What effect does a 4-inch hole have on the bass drum sound?
A hole in the resonant head generally provides a more direct attack and a quicker response. The long resonance can be reduced depending on head tension and internal damping. Controlling with a pillow, foam, or attenuator also becomes easier.
For which music styles is this chrome ring suitable?
This reference is especially suited for rock, pop, funk, metal, and contemporary music. Its use is also recommended for amplified jazz, both live and in the studio.
