3. Carefully separate the bag from the Velcro patch.
To set the adhesive, burnish the entire area of the
patch, especially the edges.
4. Install a 9V alkaline or lithium battery. Tuck the
battery into the bag and re-attach to the Velcro
patch. The adhesive under the Velcro patch requires
24 hours to achieve a full bond, so take care to not
stress the adhesive if you remove the battery bag
after the initial installation.
Second pickup source option
A second source such as a microphone or magnetic
soundhole pickup may be added (fi gure 3). The
output will appear on the ring connection when a
tip-ring-sleeve ¼" jack is inserted.
