Product Details

Installing, adjusting, and replacing Tune-o-matic guitar bridges and 'stop' tailpieces is daily work in busy guitar shops.

Our new Tune-o-Medic tools — the Bridge Jack, Post Tool and Stop Tailpiece Wrench — make the work faster and easier!

Sold individually or SAVE when you buy the set of all three tools.

Tune-o-Medic Bridge Jack
Adjust Tune-o-matic bridges quickly without loosening the strings — using the same tool Gibson used in their original Kalamazoo factory. Lift a Tune-o-matic with this jack and you can adjust the thumbscrews up or down freely, and without pressure from the strings you'll no longer damage the plating on the hardware.

With the Bridge Jack, you can even hold the guitar in the playing position and jack up the bridge with one hand while watching the 12th-fret action — when it looks right, spin the thumbwheel to hold that height.

The stainless steel Bridge Jack includes thick self-adhesive felt padding to help protect the guitar top. An extra pad and instructions are included.

Tune-o-Medic Post Tool
When Tune-o-matic bridge posts are bent, the bridge leans and intonation suffers. It becomes hard to turn the thumbwheels to set the bridge height, and the threaded posts may even be uncomfortable against the player's hand. The Post Tool makes it easy to remove, install or straighten these posts.

Interchangeable threaded brass inserts (6-32 thread for Gibson, and M4 x.75 thread for imports) snap into the Post Tool's handle. Simply thread the tool onto the post until it's flush against the thumbwheel, tighten the wheel against the tool, and hold the two together to turn the post for installation, removal, or height adjustment.

Instructions are included — we also include matching drill bits for correctly reinstalling the posts in new holes when needed.

Stop Tailpiece Wrench
The Stop Tailpiece Wrench has a thick screwdriver tip recessed into a smooth-walled socket that fits the 1/2" (12.70mm) diameter tailpiece stud snugly. The socket keeps the wrench centered, to protect the stud's plating and avoid accidents that could mar the guitar top. Made of tool steel, with a durable plastic handle. Our thanks to guitar techs Paul Verticchio and Jerry Barnstable for suggesting this tool.

Overall length is 7-3/4" (196.85mm). Inside diameter of the socket is 17/32" (13.49mm). This tool will work on tailpiece studs with 17/32" (13.49mm) maximum diameter.

Finally got my ES339 sounding like it should.

By Perry DiMarco from Farmingdale, NY
(Customer's Reviews) Saturday, July 09, 2011


This set of tools was a tremendous help in setting up my Gibson ES-339. I've had it for 2 years and it never sounded like it should even with 2 pro setups. Along with the basic setup tools I purchased previously, it made the job easy and precise. I now know that the investments I made in all my Stew-Mac tools will definitely pay themselves off in the long run. And I have no experience fixing guitars! Thanks.

These tools are so valuable in the shop. Gone are the days when you had to struggle with a Screwdriver to adjust a stop tail piece now you have a tool made for that very job. the post tool is wonderful too . I used it on a Les Paul style project I have been working on and it made installing the bridge posts a snap. Very Nice tools guys!!!!!

Well, all in all it's quite cool

OK, the stop tailpiece wrench doesn't fit on all stop tailpieces. That sucks. But the concept is cool.

The post tool is definitely a life saver when you need it but I didn't get in that situation yet.

Now, the Bridge Jack - that is a really great tool, simple as it may be. It saves loads of time and works perfectly AND it's really strong made. If you're not sure whether to buy the whole set, at least get the Bridge Jack! It pays off!

Tailpeice tool welded on an angle

By Oldy-r-goody from Canada
(Customer's Reviews) Monday, April 18, 2011


These tools work. But the build quality is pretty cheap. Think dollar store screwdriver. My stop tailpeice wrench is welded at an angle. Makes it a little weird in use. I suspect it will break. Specialty tools have their place and can be worth the cost but stewmac - you are going way to cheap on materials and build quality. The tunomatic jack bent immediately. Very very soft.

These tools are a no-brainer. If you work on these bridges, you just gotta have them.
