Inverted Felt Beater Round inverted felt beater for the K-3. Traditionally, inverted is the only way we offered the Felt Beater as it was just another option for the K-3 Ergo Kick. As we firmly believe in giving our customers as many options as possible we are now making the Felt Beater available in the standard straight shaft conformation. Just choose whether you want the straight shaft or the bent shaft and you will be good to go.. This is a standard pedal beater and will work in any standard acoustic Bass Drum Pedal. The straight beater would be used for any acoustic or upright electronic kick drum and the bent shaft is only usable, as far as we know, with the K-3 Ergo Kick bass drum.
