Another pedal I have used exclusively for contemporary dance work. Selling this Boss RC-20XL Loop Station, super versatile and reliable looper for guitar, bass, keys, vocals, kazoo and oboe etc. Perfect for live performance, practice, studio work and I know alot of folks are using it for private tuition  !   Again , this was stored on the board so marks are purely friction between pedals etc,  before storing this for years now.  Excellent condition – lightly used, fully functional
