The Keeley D&M Drive is a masterclass in functional design, born from the collaboration between Robert Keeley and the 'That Pedal Show' duo. It captures two essential flavors of drive that every session player needs. The 'Mick' side offers a refined, wide-open boost with a subtle mid-hump reminiscent of a Klon, perfect for adding 'more' to a clean amp without masking its character. Conversely, the 'Dan' side provides a rich, harmonically dense high-gain voice that leans toward a British-voiced overdrive, delivering thick sustain and aggressive clipping.

What sets this pedal apart is the routing flexibility. The center toggle allows you to instantly swap the stacking order, drastically changing how the circuits interact"pushing the high gain with the boost for lead sustain or using the boost to lift the volume of the drive. The build is robust, though the enclosure is predictably large. While the price point is premium, you are essentially getting two professional-grade pedals that play exceptionally well together. It's a 'desert island' drive for the intermediate to pro player who needs to cover everything from bluesy grit to saturated hard rock. My only minor gripe is that the high-gain side can get a bit compressed at maximum settings, but the overall clarity remains impressive throughout the sweep.
