Expression Ramper X3 is more than the sum of its parts. It starts with three individual Expression Rampers, which are devices allowing you to pick two expression settings and move between them, either in one motion or as a continuous LFO activated by a footswitch. It then adds tempo syncing, new LFO shapes, and other external controls, all in one tidy box. It is the ultimate device for getting new sounds out of your existing expression-enabled pedals.
