Clone of the 29pedals input buffer EUNA. Velcro is attached to the back. This is a sale of the unit only. I bought it to build an effects board, but I've been too busy to even try it out. I'm selling it to organize my equipment. If you have any other questions, please feel free to ask. Also, I am not accepting price negotiations. If you purchase it at the same time as other items I have listed, I will offer a small discount, so please let me know. NCNR (No Claims, No Returns) except for damage during shipping. Shipping is scheduled for 10/12 (Sun) and 10/13 (Mon).
