Fast, accurate saddle installations! Slot an acoustic guitar bridge easily and accurately every time. A StewMac exclusive.

We designed this handy jig here in our shops, to solve the tricky router alignment problems you'll encounter when creating or correcting a bridge saddle slot.

It's become a repair shop "must-have," with versatile time-saving uses that will give you easy, accurate results every time.

Slot a new bridge
Slot for a compensated saddle—split saddles too!
Fix an incorrectly located saddle
Flatten the bottom of a slot for an undersaddle pickup
  (crucial for proper pickup response)

The jig works seamlessly with our Precision Router Base and your Dremel. Don't have a Dremel? An adapter for the popular Bosch Colt router is also included (you can drill it to fit other brands of laminate trimmers, too).

Simply clamp the jig at the guitar's soundhole and tailblock. It's made of clear acrylic for easy positioning, with sponge padding to help level the jig on arched soundboards. Thumbscrews allow precise fingertip adjustment of cutter alignment, saddle compensation, slot length and width. Clear acrylic adapter plates are included.

Instructions are supplied with the jig. Clamps, router base and Dremel not included.

TIP: Before using the jig, you'll need to know precisely where to rout. The Saddlematic and the Intonator take away the guesswork.

Great Jig, but not seamless with Precision Router Base.

By Ben from Austin, TX 
(Customer's Reviews) Sunday, November 17, 2013


I think that both the Saddle Routing Jig and the Precision Router Base are very well made, and on a whole, are time savers. The rating I would give each individually would be five stars. The problem I have had comes when I use the Saddle Slotting Jig in conjunction with the Precision Router Jig to cut saddle slots. There is still enough wobble within the Dremel that the bits end up cutting a channel that is .018 oversized from the StewMac Carbide Downcut Bits (which are also a great part). This clearly means that if you use the 3/32 (.094) bit, you end up with a channel that is .112, and if you use the 1/8 (.125) bit, you end up with a channel that is .143 wide. I have talked to the folks at StewMac, who were very friendly, and they recommend I use my trim router, which I will do in the future. However, I disagree with StewMac's claim of the Saddle Slotting Jig working seamlessly with the Precision Router Base. Again, both are very well made, I have just found that they do not create an accurate slot width.

Good Tool

I just used my new saddle routing jig on an acoustic that came in to the shop with a broken bridge plate and a missing saddle. Set up was easy and quick once I had the rout marked out, and the job was over and done quickly. You do have to be very careful when tilting the router bit into the plate.

The price of this tool makes it worth buying. If you want to make a similar jig it might cost a lot less in materials, but will take a lot of time you could be spending doing other stuff. its easy to use and accurate. i used it with my bosch router. theres a few tricks you need to know while using the tool so if you arent experienced maybe do a test run on a scrap bridge to get a feel for the router and how it cuts in the jig.

Great professional jig

This flexible jig has saved me countless hours piecing together jigs on a case-by-case basis, or in developing my own permanent jig.
Quick, accurate and repeatable results.

Works Great with the Bosch Colt

By Nate Clark from Ithaca, NY

This jig works great with the Bosch Colt router. Drill a 1/16" hole at the saddle locations at the e-strings' pin holes. Use your holes for aligning the jig. Then mill your slot in 2 or 3 passes with a 1/16" downcut bit. Make one final pass at full length and depth with the 3/32" for a nice and clean saddle slot.

Use this great tool with care

By Steve West from Colwich, Kansas

This is a great design, easy to use and does the intended job well. I can't imagine cutting a saddle slot without it. However, one should be careful when the router gets to either end of the cut, as the router seems to take an exceptionally hard bite at the end, and the router bit can move slightly left and right, causing resulting in a slightly wider opening than the slot. This is easily avoided if the operator will hold the router tightly in his (or her) hand as the router reaches the limits of travel.

As always, any tool needs the attention of the operator to work well. This fine tool is no exception.

Great but could have tighter tolerance

It is a great tool for bridge work. I found the guide and router base have a few mm of slack. Not bad just have to take care to keep it square on one edge.

Great product easy to use.

Had a jig I made myself and it worked fine for years, but once I tried one of these that friend had I was sold. Almost idiot proof, smooth, precise tight fitting action. Easy to clamp down.

Brilliant!

An excellent piece of kit. Don't let the high price put you off. It's worth it, for pro results. And it's very easy to use too! Glad I bought one.

This jig makes precise slotting easy

By Dogwood Guitars from Kansas City, MO

A heavy duty, well-designed jig that makes slotting a bridge easy and precisely accurate. I use plunge cuts and gradually increase the depth of each pass to obtain perfect results. Nice flat slot bottoms for good pickup contact too.
