Look at how beautiful this Roland sde 2500 is cosmetically. It's really in outstanding shape. All the knobs are there, no scratches. The rack ears are in good shape. The functionality is all there too, one small issue is with the 2 x two times delay button you may have to push it once or twice to get it to engage or disengage, other than that everything works as it should really really good shape. It's got a +4 dB - 20 dB push button on the back for levels. This unit does great flanging, choruses, long delays up to about 650 milliseconds. No noise or scratchy pots all the LEDs work as they should and that classic Roland warmth. Why am I selling it? I don't know. LOL it's time to give you a chance. Hey I'll ship this thing packed well and I'll get it out to you real quick that's the nature of my professional ethic. Good luck and you're welcome.
