Q. How Do I Install this?
A. Using the 7/64” Allen Key provided unscrew the machine screw in the strap lock button to separate the parts. Place the keyhole ring over the end pin and slide it to the narrow end of the opening. Slip the plastic cover plate into place with its forked end wedged under the strap lock button flange and line up the screw holes. Reinstall the strap lock button using the Allen key and firmly tighten. Acousti-Lok does not block the battery cartridge. Will not fit TAYLOR® Guitars original AA battery powered EXPRESSION SYSTEM®. If the plastic cover plate won’t slip into place, the strap pin flange may be slightly bent. Rotate the Acousti-Lok to try it from different directions. If necessary, sand the underside slightly on a flat surface just until it’s thin enough to slip into place.
Q. Will this work on the original AA battery powered EXPRESSION SYSTEM® by TAYLOR® Guitars?
A. No. The internal shape of the AA strap button is curved and not as open as the 9v strap buttons. You could consider having the system updated to a 9v system. Contact TAYLOR® for details.
Q. I have a TAYLOR® Guitars but I don’t know which Acousti-Lok to buy?
A. If your guitar has a 9v EXPRESSION SYSTEM® battery box part number MN272 will work.
Models built in the 90's and early 2000's with the slider controls mounted on the body have systems made by FISHMAN® and the Standard part number MN270 will work.
Q. Will this work on recessed or flush mount jacks?
Q. Will the end of my strap block the output jack?
A. The amount of extra material that goes beyond the strap pin opening on a guitar strap varies considerably. While this material may seem to partially block the output jack opening, it is flexible and can rest against or lay over the guitar cable with no issue. If you’re running into an issue with your strap you may be able to trim the end of the strap, depending on how it’s made. Also, consider using a right angle plug into your guitar if you’re not doing so already. That may allow a longer strap end to rest over the jack once it’s plugged in. Acousti-Lok was designed to be as stealth and unobtrusive as possible while serving its ultimate purpose, securing the strap to the guitar with strap locks. A longer or larger design may not fit into some guitar cases as well and would protrude further off the guitar.
Q. What Acousti-Lok would work for K&K SOUND® pickups?
A. Standard Thread Acousti-Lok, MN270
Q. What size allen key wrench is needed to tighten the strap button?
Q. Will Acousti-Lok work with DUNLOP® Straps Locks?
A. It's easy to convert Acousti-Lok to be used with DUNLOP® strap locks, but you will need a shorter screw. Simply loosen the screw holding the Acousti-Lok strap button in place and replace it with the DUNLOP® strap button.
We use and recommend a socket head cap screw #6-32. Screw lengths needed are 1/4" long for FISHMAN® and LR BAGGS® style (MN270 & MN271) and 3/16" for the TAYLOR® 9v EXPRESSION SYSTEM® (MN272).
If you're handy you can file or grind down the original screw to the appropriate length. Please note the screw can not protrude beyond the surface of the underside at all or it will scratch your guitar.

Q. I have a Taylor with a 9v Expression System from 2007 but it looks different than the one you show on the package and website. Which Acousti-Lok will fit my guitar?
A. For the first few months of production in 2007, Taylor 9v Expression System battery boxes used a different thread with a chrome or gold jack cap and a couple thousand guitars were built this way. If your battery box looks like the photo below you can remove the cap using pliers and install Acousti-Lok MN271 for metric output jacks.
