Hardware

Note: Hardware letter will be used in steps below.

Note: Screw "B" shown as machine screw for threaded inserts (Wood Core). For the 3D printed Core option these screws are self tapping.

Note: Screw "E" only for 3D printed Core option.

Step 1

Mounting the Rails

Attach the Left Rail and Right Rail to the Core using QNTY 4 "A" screws per side.

Caution: Do not over-tighten to prevent stripping.

Step 2

Bridge and Ground

Feed the Ground Wire through the hole in the Core from the bottom so that just the bare end of the wire is exposed.

Bend the bare end so it lays flat and points as shown.

Attach the Hardtail Bridge to the Core using QNTY 4 "B" screws, making sure to clamp the exposed bare end of the Bridge Ground Wire.

Lightly pull on the Bridge Ground Wire to ensure it is securely clamped by the bridge.

Step 3

Pickup Sub Assembly

The Pickups come with pre-soldered electrical contacts.

Caution: Handle the pickup wires carefully to prevent damaging the solder joints or breaking the electrical contacts free from the wires.

Using a screwdriver, remove the 2 springs and screws from the Pickups.

Insert the screws through the holes in the 3D printed Pickup Mount, flip the subassembly, and then add the springs over the screw posts as shown.

Mount the Neck and Bridge Pickups to the Pickup Mount using a screwdriver.

Note: The 'notch' in the Pickup Mount points towards the Neck.

Note: The Pickups are labeled Neck and Bridge on the back of the pickup, denoting their proper installation position.

Note: For the SS Single Coil configuration, the Bridge Pickup is mounted directly to the Bridge using QNTY 3 screws and springs.

The screws can be tightened / loosened to adjust the height of the Pickup relative to the strings (during guitar Setup at the end of the Core assembly).

Step 4

Mount the Pickup Sub Assembly

Feed the pickup wire electrical contact ends through the hole in the bridge pickup cavity in the Core.

Ensure the Neck Pickup wire routes through the slot running between the pickup cavities and place the Pickup Subassembly onto the Core being careful not to pinch any of the wires.

Fasten the Pickup Subassembly to the Core using QNTY 8 "B" screws.

Step 5

Backplate Sub Assembly

Align the hole in the Latch with the hole in the Backplate as shown.

Locate the Latch Screw "C".

Insert the Latch Screw "C" through the Latch and fasten the Latch to the Backplate.

Caution: Do not over-tighten.

Note: Screw can be loosened / tightened to adjust how freely the Latch rotates.

Step 6

Wiring and Mounting Backplate

Clip the electrical contacts onto the Backplate Subassembly following the wiring diagram below.

Route the wires through the slot in the Backplate. Make sure the wires are fully seated in the track and not sticking above the 3D printed walls.

Optional: Use a piece of electrical tape to hold the wires down.

Tuck and excess wires back through the hole in the Core into the pickup cavity to remove slack.

Place the Backplate Subassembly onto the Core.

Caution: Be careful not to pinch any wires.

Fasten the Backplate Subassembly to the Core using QNTY 4 "B" screws.

Step 7

Mounting the Neck

Place the Neck into the neck pocket in the Core.

Holding the Neck and Core together, flip the assembly and position the Neck Plate.

Insert the QNTY 4 Neck Screws "D" through the Neck Plate and Core, then fasten them using a screwdriver.

Caution: Screws should be tight to fully secure Neck to the Core, but over-tightening can strip the wooden Neck.

Step 8

Strings and Setup

This step is not intended to be a detailed guide on how to string / setup a guitar.

There are countless resources / guides / tutorials / videos online on how to perform a standard guitar setup.

The kit comes with a set of Ernie Ball Regular Slinky Strings (Gauge 10 - 46).

Insert the string through the hole in the back of the Bridge and through the bridge saddle. Pull through.

Repeat for all 6 strings.

Pull the string through the hole in the corresponding tuning peg.

Measure out approximately 2 tuning back of slack in the string and cut the string using snips or wire cutters.

Rotate the tuning peg to wind the string around the post.

Note: An Ernie Ball Power Peg String Winder (affiliate link) can help you save a lot of time here.

Repeat for all 6 strings.

Congratulations!

Your Hardtail Bridge Core is Complete :)
