Another versatile and compact, great-sounding and indestructible unit from Boss. (YouTube link to my original inspiration for collecting these old units: they're great effects for not much money!) Skip the overdrives and go straight for the modulations -- they are excellent. I particularly like that you can set your delay time in 1 millisecond increments (up to 1 second, if I recall), so you can match your song or arrangement precisely. Everything works as it should: buttons, expression, display, and jacks. Comes with original power supply.
