I got all my best analog pedals used for the simple reason that It was hard to find them new. As long as they are not faulty, old pedals will do the same job as new ones. Don't get frightened to purchase a used unit if it's not in its best-looking shape or has loose bolts. Everything mechanical can be fixed - faulty circuits are the ones that are hard to repair. Ensure to maintain the foot switch & pedal for smooth use with the right care and mechanical oil after.
