This is a Sustiniac sustainer. When turned on, the sustain continues until the battery runs out. Please check YouTube for the effects. All parts are included. Fully functional. The second photo is a picture of the new product from the product page. Although not in the first photo, rubber tubing and cable ties are also included. Installing a Sustiniac requires specialized knowledge, so we recommend that you confirm with a local repair shop whether they can install it before purchasing. The musical instrument store "Aporon" in Niigata is the import agent, so you can be sure to have it installed if you send it with your guitar. - Parts: Parts for electric guitars - Switches: 2 red switches - Wiring: Multiple wires included - Hardware: Screws and sockets included - Other: Electronic parts for guitars Thank you for viewing.
