The Double Barrel system is an all-discrete, class A, dual-channel
pickup/microphone system that is built right onto a four-pin strapjack. It pairs
the Ribbon Transducer with our own FET condenser mini-mic and features
independent buffered outputs for the pickup and mic channels. The preamp
powers the mic, making phantom power from an outside source unnecessary.
Caution: If you are running the outputs of the Double Barrel into a
preamp that provides phantom power for an onboard microphone, be
sure to turn phantom power off.
The Double Barrel circuitry is specifically tuned for the L.R. Baggs mini-mic, but an alternate non-tuned mic input is also provided to allow the
Double Barrel to be used with most other popular mini-microphones. Connections for alternative microphones are discussed in section 6.
We recommend that this system be installed by a professional dealer/installer. We do not provide installation advice or support for home or
hobbyist installations. Installers: please read the instructions carefully before proceeding. We will not be responsible for any product or
instrument damage, or personal injury resulting from installation, improper installation, use or misuse of the product.

1. For proper installation, this jack requires a clean 1/2" hole in the tail block of the instrument. If the guitar has this hole, proceed to step 2. If not,
start by placing a piece of masking tape on the outside of the instrument over the drilling area (to avoid chipping the finish), drill a small pilot
hole in the tail block and then follow with a step drill.
2. Remove the strap ring, retaining nut and one washer from the end of the jack. There should still be one star locking washer, one flat washer and
a nut remaining on the mid section of the jack. Bring the jack down into the sound hole and through your pre-drilled hole in the tail block. Using
the internal nut (be sure to include the flat and star washers), set the proper depth that will allow the smaller threaded section at the end of the
jack to protrude out of the end of the guitar. When the jack is fully seated in the
tailblock, there should be about 2 threads of the small threaded
section remaining inside the hole.

Notes:
1. For optimum performance of this pickup, the saddle slot must have a clean, flat surface free of any debris or over-spray from the finish. The slot
must be a minimum of .125" (1/8") deep but we suggest a depth of .187" (3/16") to avoid excessive saddle tilt (see figure 5, which illustrates
excessive tilt).
2. Installing a .090" pickup in a .120" slot is not recommended.
3. Do not remove the black material that is affixed to the bottom of the pickup.
4. Avoid unnecessary hard bending of the pickup. Repeated removal and replacement of the pickup during the course of the installation is not
