Critic Reviews

Boss DR770

soundonsound.com

The Boss DR-770 impresses as a versatile, no-nonsense drum machine with a rich collection of sounds and user-friendly features. Its high-quality samples and intuitive interface make it a worthy successor to the DR660. While the effects are basic and the display could be brighter, the DR-770's new sound set, dual footswitch capability, and abundant user pattern space are significant enhancements. However, it falls short in MIDI real-time control and lacks multiple individual outputs, which might limit some advanced users. Overall, it's a solid, all-around beatbox ideal for both studio and live settings.

Quick, easy beats for cheep

Interface designed by Roger Linn, it sounds good (better when run through some effects). It's usually only $100, so why not get it and make some sweet beets?
