I brought this to the studio 4 or 5 times, and then stored it in a equipment room, never using it again. There is Velcro on the back of the effector to attach it to a pedalboard. Please be aware of this. (See photo 6) I checked the operation for this listing, and there was no scratchiness, and the effect worked without any problems. I will include the box, catalog, and other accessories that came with the purchase. (Everything in the first photo is included.) Please feel free to ask any questions in the comments.
