I bought this to install in my Martin Backpacker acoustic guitar but turns out it's 1/32nd of an inch too thick for the slot. As such I took it out of the box to measure, but other than that it's untouched, like new. Hopefully it can find another home! It's an excellent pickup; here's the description from the dealer I bought it from:

This model of the LB6 pickup includes the LR Baggs StrapJack internal mount 1/4" endpin jack in dark bronze color.

The LR Baggs LB6 is the pickup that made Baggs famous. It has been around for more than 20 years, and is the preferred choice for professional studio and stage musicians. The LB6 offers incredible string sensitivity without picking up excessive guitar body noise. This gives the LB6 excellent presence, as well as superb clarity for cutting through a mix.

Outstanding for lead and fingerpicking, great for all styles of playing. Excellent resistance to feedback, even includes a feedback inhibiting circuit. This is probably the most versatile of all of the LR Baggs pickups.

The LB6 pickup has relatively high output and can plug directly into most direct boxes and effects equipment, or it can be used with an onboard or outboard preamp such as the Para Acoustic DI.

Note: LB6 saddle is an unshaped square blank, requires shaping and intonation to match your existing saddle, professional installation recommended.
