DD Eflex Bt9


electronic drum kit with bluetooth connectivity

ddrum first introduced the E-Flex in 2022, offering responsive mesh heads for quiet, responsive playing. The new E-Flex BT9 takes those basics and expands upon them, providing more bang for the buck — in the most literal sense. The BT9 has a wider rack and bigger 8-inch mesh pads, compared to 6 inches, on the three toms. Whereas the original E-flex offered just a bass drum controller, the BT9 now has a 10-inch bass drum pad with bass drum pedal. The snare drum also has a mesh head with dual-zone playability, which is great for rim shots, ghost notes, and other nuances, contributing to an overall realistic performance.

With the E-flex BT9, ddrum also expands the cymbals to 10.5 inches, compared to 9 inches. A fourth cymbal pad is now included and can provide a second crash with choke function, in addition to the ride cymbal with bell zone and choke, and hi-hat with controller. To offer players more practice options, the BT9 offers a new module with Bluetooth connectivity, allowing drummers to play along to their favorite tunes with out the need of a cable.

Of course, one of the best parts of an electronic drum set is playing with the preset kits, and the BT9 offers more to choose from, a total of 20 with great sounds. ddrum’s bass drum and hi-hat controllers are highly responsive. In Double Bass mode, the hi-hat controller can be used as a second bass drum.

With the E-flex BT9, the ddrum team has pulled out all the stops to get beginners playing, even including a drum throne, drum sticks, and drum stick holder. The onboard metronome is a great tool for beginners and experienced players alike.

Sleek and compact, the E-Flex BT9 kit from ddrum takes the entry-level electronic drum kit to new heights, setting a higher standard for quality and control.
