USER GUIDE
BLACKSTACK™ SOUNDHOLE PICKUP
Page 2
Requirements
BlackStack is designed to fi t most steel string, fl at-top guitars with a minimum
3 5⁄8 – inches (9.2cm) diameter soundhole. We recommend stringing your guitar
with bronze or phosphor bronze strings to achieve the best response from the
pickup.
Description
BlackStack’s battery-free design incorporates double-stacked neodymium
magnets for a brilliant acoustic tone, greater hum cancellation and a vintage
sound that can cut through any mix. The provided 5 foot cable features a
premium TA4 mini-XLR connector to ¼” combination endpin jack for temporary
or permament installation.
Individual string output can be balanced through use of BlackStack’s adjustable
pole pieces. Use the included hex wrench to adjust the pole pieces higher or
lower. Adjusting the screws higher or lower will result in more or less output from
the string closest to the screw.

Installation
To temporarily install the pickup, loosen the clamps with a Phillips screwdriver.
Position the pickup in the soundhole, parallel to and as close to the end of the
fi ngerboard as possible. Gently re-tighten the clamps. For now, run the cable out
through the soundhole.
BlackStack was voiced to provide optimium sound using the built-in plastic
clamps, however these may mar your guitar's fi nish over time. An optional set of
cork clamp inserts are provided to further protect your instrument’s fi nish.
Precaution: Don’t let the pickup cable rest on your guitar’s fi nish for long
periods of time. The rubber jacket could interact with the fi nish and leave a
permanent mark.
If you travel with your guitar, we strongly recommend removing the pickup to reduce the likelihood of damage during shipment. If you perform regularly or store
the guitar for long periods with the pickup in place, we recommend that you
have the endpin jack permanently installed in the guitar. Installation instructions
for professional installers are available from Service & Support at www.fishman.
