Piezo Contact Type Pickup with Removable Pickup and Volume Control for and More AD-35 Guitar, Ukulele, Violin, Mandolin, Banjo, Cello,

Since it is a passive type, it does not require a power source such as a battery, but it is a very easy-to-use pickup with a volume control. Also, as you can see in the image, the cable is detachable, so I think this makes it a very user-friendly pickup. The pickup is attached with the included double-sided tape and can be reused to a certain extent, but since the adhesive is generally quite strong, it may damage the paint when removing it if the paint is delicate. If you are concerned, we recommend that you either adhere it to an unpainted surface (for example, the bridge of a guitar), or use commercially available double-sided tape that can be reattached multiple times and is easily removed. However, please note that we cannot provide compensation if the paint is damaged when used. Because it's a passive pickup, it doesn't require batteries or other power sources, but it also features a volume control, making it extremely user-friendly. The cable is also detachable, as shown in the image, making it another convenient pickup. The pickup is attached with the included double-sided tape, allowing for some degree of reusability.
