Handmade pickup for double bass. This type is placed under the foot of the bridge on the low-string side. It has a strong low-end push and is also good for use as a base mixed with other clear-type pickups. If you are concerned about the sensor part directly touching the soundboard, you may want to refrain from using this model. We also have wooden base models, so please inquire if you prefer those. Please secure it to the tailpiece, etc., with an arc-shaped clip or a cable tie. It is new, only tested for operation, but has a handmade feel.
