The McIntyre MT-100 Transducer Disc Mandolin Pickup is an internally mounted soundboard transducer designed specifically for the frequency range of a mandolin. A prewired endping jack is included, along with installation instructions.
This pickup is mounted inside with several options for jack placement. It can be used with a jack installed through the side or with an endpin jack through the tailblock, which requires enlarging the hole in the tailpiece. This can be a tricky installation, but with good instructions included and advice from Carl (if necessary) the sound is more than worth it. This pickup is being used by the folks at Weber Mandolins.
The output of this pickup is sufficient to drive an amplifier directly in most cases. If you are plugging into a mixer board or PA system or need to run the signal through effects pedals or other equipment, you may need a preamp to increase the signal strength to match that equipment. Preamp not included.
