Keeley built the D&M Drive (KDMDRIVE-U) as a dual-channel overdrive and boost pedal developed in collaboration with That Pedal Show. The unit housed two discrete gain stages — a Boost side and a Drive side — on a single pedal, with a switching system that allowed the user to select the signal chain order of the two channels.

The Boost side was designed as a high-voltage circuit, positioned between a clean boost and a driven overdrive character, with a distinct midrange voice that could be dialed in or reduced depending on the application. The Drive side offered multiple gain stages, described as delivering a range from a low-gain overdrive to a heavily saturated, tube-like gain with high sustain and quick attack. Both channels could be run independently or stacked in either order via a toggle switch. The switching system was also designed to allow integration with external pro switching systems for independent channel control. Daniel Steinhardt of TheGigRig contributed to the switching specification during development.

Owners tracing compatible power supply requirements, switch replacements, or internal components should consult a qualified guitar technician or effects repair specialist for hands-on assessment.
