I’m the original owner. It was used about a dozen times for gigs and about 5 years for practice. I’m no longer playing metal, so switched to a single pedal. Hard shell case, manual, spare parts and 2 extra beaters are included. Infinitely Adjustable Cam: The patented cam design allows drummers to quickly transition the pedal feel anywhere between an Accelerator (for speed and control) and a Turbo (for power and consistency) style drive. Floating Rotor Drive System: This system allows the shaft to rotate independently of the rotor, directly transferring energy from the footboard to the beater for enhanced power and precision, while reducing friction with a multi-bearing system. Floating Swivel Spring: This system increases efficiency on both the downstroke and return stroke, providing less resistance and an incredibly smooth feel. Convertible Drive: While it comes standard with a double chain drive, the pedal includes a nylon strap for easy conversion to suit different playing preferences. Stability Enhancements: The pedal features a Tri-Pivot Toe Clamp System with self-aligning rubber pads to firmly grip any bass drum hoop diameter, and a non-slip rubber grip base plate for increased stability. Single Post Casting Design: The double pedal’s design allows for closer placement of the auxiliary pedal to the hi-hat stand, facilitating easier movement between them. Included Accessories: The pedal comes with a molded case, a drum key with a clip mount, and dual-sided felt/plastic beaters.
