This is a reverb effects pedal made by tc electronic. Although it's inexpensive, it offers the essential types: spring, hall, and room. Each knob is easy to understand and adjust. I purchased it at a musical instrument store but am selling it because I no longer use it. Operation has been confirmed. I only used it at home, so I didn't incorporate it into an effects board, and there is no Velcro attached. In addition to the main unit, the box and instruction manual are included. Shipping may be delayed due to work. Basically, I ship on weekends. - Brand: tc electronic - Model Name: Skysurfer Reverb - Function: Reverb - Connections: Input/Output jacks - Features: True bypass - Accessories: Instruction manual, box [Excerpt from Soundhouse's description] A reverb pedal that achieves a clear and beautiful sound without affecting the guitar's tone.
