I purchased this item used, so the details are unknown. While trying out various pedals, I was drawn to the springs equipped on the underplate and decided to buy it. I thought it was a wonderful pedal with a smooth and responsive return, but it didn't suit my feet. Therefore, I haven't used it much. Unfortunately, I am putting it up for sale. It has been cleaned, disinfected, and greased. There are some scratches from the previous owner, but there are no operational problems. The beaters are unused. The item is the main body only, without a case. Please refrain from price negotiations as shipping is included.
