The DM-3 was last analog delay pedal produced by Boss. The circuitry is similar to the DM-2’s but it isn’t identical. The DM-3 has a built in high speed noise reduction circuit and an additional filter. It’s also got a direct output that can be used to create a stereo effect. The delay time is variable between 20ms and 300ms just as the DM-2 and the control layout is also identical. The knobs on the DM-3 stands out when comparing to other Boss pedals. They only featured on the DM-3 and early versions of the CE-2B.
