Historical Context and Positioning in the Range
The Bass Drum O's Original is an essential accessory for drummers who want to add an opening to their bass drum resonant head while maintaining a neat finish. This "Original" version stands as a classic and proven solution in the range, designed to combine aesthetics, practicality, and ease of installation.
Who This Drum/Instrument Is For
The Bass Drum O's Original is aimed at all drummers, from beginners to advanced players, who want to optimize their setup without changing the entire head. It is particularly suitable for styles where a controlled bass drum that is easy to manage live and in the studio is desired: rock, pop, funk, metal, contemporary music, as well as amplified jazz. It is also an excellent choice for technicians and backliners who need a reliable and repeatable solution.
Features and Innovations
Designed to be easy to install, the Bass Drum O's Original consists of a "male" part to be placed on the outer side of the head and a "female" part to clip on from the other side, ensuring a solid hold and a clean edge around the opening. The integrated adhesive provides stable placement, while the included alcohol wipe helps prepare the bonding surface to maximize adhesion. The result is a clean opening, ideal for an internal microphone, facilitating air evacuation, or simply for the look.
Sound
Adding an opening to the resonant head changes the bass drum's behavior: generally, it results in a more direct attack feel, easier placement of an internal microphone, and simpler control management (pads, foam, dampeners). The Bass Drum O's Original is not a shell material but a head accessory: it mainly contributes to a more immediate response and a clearer projection in a mix, often with less long resonance depending on head tuning and internal damping.
