By far the most transparent and authentic sounding pickup for acoustic guitar. It mounts through the end pin so no one will even know it is there. Used by stars worldwide including Eric Clapton, Mark Knopfler, David Knopfler, Brian Adams, John Fogerty and many, many more.

"The Martin feels and plays totally like an acoustic instrument without any of the previous drawbacks of amplification it had (Fishman*), working perfectly with no hums or feedback too- the kind of quality of balance spread too I'd not expected. The sound doesn't seem to be coloured in any of the negative ways most pickups generate.... a world class pick-up for all stages of musicians...." David Knopfler
