Saddle Routing Jig

About This Item

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 tool!!!

I love this set up. Works like a champ. The first one I routed I ended up with a left handed bridge because I wasn't paying attention to top and bottom. I guess one of these builds will now be for the leftys out there. New and unchartered territory.

Easy set-up. Easy to use. I used a Dremel with base. Seems to be exactly correct.

I bought this jig for a custom bridge build for a customers 1960's J45. This model had the adjustable saddle with the 4 bolts going through the top and he wanted to improve guitars the tone. The jig did exactly what I needed and it was easy to work with. Thanks Stewmac.

Hesitated because of the price...seemed to be a good chunk of change for some plastic plates...well, I gotta say, these are some nicely jigged pieces of acrylic.

Up and running on a test piece within minutes. And the onto a vintage Guild left handed conversion. Clean. Quick. Stress free.

Could you make your own Jig? Yes you could. But this is perfectly designed. I don't have the luxury of time when it comes to Jig making. Very happy with this one.

Used it with my Bosch Colt router, 3/32" bit first pass, 1/8" bit for final pass.

I use the saddle routing jig on my new builds and I have found a new use. I also use it to cut the end grafts. I can cut straight and tapered grafts accurately with a perfect depth of cut. I had to create a jig to hold the instrument and a table to fit over the lower bout to clamp the Saddle routing jig to. I now can cut end grafts in minutes with a high degree of accuracy on guitars and ukes.

You get what you pay. Expensive, you could probably build it yourself. It's nice to not have to though.

Customer wanted to replace the cracked and lifted bridge on his '65 left hand Gibson LG-1. Since it was left hand, I had to install the #4927 unslotted/undrilled pyramid bridge.
It was my first time using this jig, so I practiced on a junk guitar first. Watched Dan's video of his LG-2 project (thanks Dan!), and followed his advice of making plunge cuts. A new bone saddle popped right in after final shaping and intonating by hand. Plays great!

This is the second saddle slotting jig I've purchased from StewMac, the first one was years ago and not as well developed and did not fit the StewMac Dremel router base well. I had problems keeping the router base properly oriented over the bridge. I bought this one because they seem to have addressed those issues. With this version my StewMac Dremel routing base fits nicely into the jig and
the tolerances are reasonably tight. I would prefer routing with a better router but the size of most laminate routers makes it difficult to manage in a small area like the bridge saddle slot. I've never trusted the bearings on a Dremel but if it's fairly new, the bearing are not badly worn and a good saddle slot can be cut. But buy the down-cutting burs. Others will wander and chip, it's one of those operations that has a very high pucker factor, this jig helps reduce the stress. Still requires your complete attention! And, like most things, it's all in the prep.

Good but not perfect

I have been using this jig many years now. The concept for the jig is great! The Dremel is not a great tool, to much play. Work best if you drill your way (by tilting the Dremel and drill a row of half "holes" with the router bit) in the middle of the slot and then use feeler gauges and the guide to route both sides of the slot, just kissing the wood.

Recently I found out that the acrylics in the jig was not as flat as they should be. I've been having some problems not getting the slot flat in the bottom. Flattened all the acrylics with my drum sander, the screws was easy to remove. I also noticed that the acrylic was not as stable as it should be. Even the weight of my small Dremel will bend the acrylic frame a bit. When using clamps and if the top of the guitar has an arc, the jig will follow the curve. And the bottom of the slot will follow to.

I have now reinforced the topmost frame with a steel sheet. I clamp it to the center and use thin slivers of wood to fill up the gaps between the guitar top and the underside of the jig before I do the routing. Now and only now the bottom of the slot is dead flat.

The shape an form of the jig is perfect, the material should be aluminum or some other metal instead of acrylic. That would be very nice!

I give my improved version of the jig and the method to use it five stars.
