MSP Contrabass Pickup - Used, with Manual

Used MSP Double Bass Pickup.
Comes with instruction manual. Original box is not included. All parts shown in the photos are included.
This pickup is used by inserting a magnet into the back of the double bass and sandwiching it with the pickup on the top.
It shows signs of use, but the sound output is normal.
The tone is warm and does not have the characteristic piezo smell. It sounds natural. It does not produce a scratchy sound when played with a bow.
It produces a natural sound even with gut strings and is easy to handle, but the drawback is that it is prone to feedback when the output is increased.
I used it as a secondary pickup in conjunction with multiple pickups. It was easier to use when combined with pickups that have a fast attack, such as KNA Piezo, Fishman BP100, or Realist Lifeline.
The mounting clamp is from a different source, so
when installing, there was a gap between the clamp and the sandwiched cable. I had to wrap the cable with electrical tape to thicken it to secure it in the clamp.
Please be aware of this when using the clamp.

The setup range is wide, and the sound and volume change depending on where you attach it to the top. If you find the right spot, you can play with a great sound.
This item is also listed on other flea market sites, so it may be removed early.
