For sale a Boss DR-670 DR Rhythm drum machine / pattern programmer , used but in mint condition. the DR-670 is quite a serious unit for its size , 200 preset patterns and 200 user pattern slots gives plenty room to build your own tracks. the bass guitar ' fret ' layout allows musicians who aren't keyboard players to program basslines. mainly used by singer-songwriters , guitarists , bedroom producers looking for a reliable no fuss backing band. it has midi in/out ports , L/R outputs . you can use batteries in this unit that makes it fully portable but it also comes with a roland power supply. it comes with a manual and original box. cheers !!
