From the Legendary DM-2 to the Modern Delay Machine
Faithful to the DNA of BBD delays from the 1970s and the aesthetic of the legendary BOSS DM-2, the DM-101 brings this sought-after analog character into a contemporary platform. Eight precisely controlled internal BBDs provide access to longer delay times, enhanced clarity, and new stereo architectures, while preserving the organic signature that made BOSS delays famous.Who Is It For and What Are Its Uses?
Ideal for intermediate to advanced guitarists and bassists, the DM-101 covers rock, pop, blues, ambient, shoegaze, and experimental music. It excels in the studio thanks to its memories and MIDI sync, and on stage with its tap tempo, subdivisions, and stereo routings that easily integrate into a modern pedalboard or amp/direct rig.Technical specifications
