Handmade pickup for a double bass. This type is inserted into the gap on the side of the bridge. A gap of about 6mm is required, so in principle, modification to widen the gap will be necessary for all bridges. Made based on a popular pickup that produces a soft, low-pitched sound and has a decent output. Includes an R-shaped clip for fixing, cable ties, etc. It's new, only tested for operation, but has a handmade feel.
