12 String Installation

Where there is insufficient room to drill a hole beneath the D and G bridge pins, BridgeMagic© may be installed using this Adapter Kit and locating mounting holes beside the two E string bridge pins. This makes it suitable for a 12-string guitar.

  • Included Components

    • 1x Nylon end cap
    • 2x Nylon sliders with screws
    • 1x Winged nylon end cap
    • 2x Alloy extrusions plus O-ring
    • 1x Pack adhesive cover dots

  • Tools Required

    • Drill with 4.5mm (3/16") bit and countersink bit
    • Hacksaw
    • Phillips screwdriver
    • Tape measure

  • If you're competent using tools the installation is straightforward, otherwise installation by a guitar technician is recommended.

  • The guitar in the images below has been cut away for illustration purposes only. Please do not cut into your guitar!

  • Remove strings from bridge. Measure inside guitar from the end block to the apex of cross brace and subtract 5mm (1.4").

    A small mirror and flashlight may assist you.

  • Cut the square end of the alloy (not the angled end) to this measured length and assemble BridgeMagic©. Push the sliders onto the alloy, and slot on both plastic ends as pictured.

  • Check for pickups/wiring and crossbrace locations inside guitar to ensure you do not drill through. Drill and countersink two 4.5mm (3/16”) holes in the bridge either side of bridge pins, allowing room for the 8mm cover dots.

  • Slip BridgeMagic© into the guitar through the sound hole, place the screws into the pre-drilled bridge hole and thread them into the nuts at the top of the nylon sliders.

  • Ensure BridgeMagic© is positioned correctly inside the guitar, with the nylon end cap centred under the cross brace. Tighten the screws evenly to hold BridgeMagic© in place.*

  • Restring the guitar. Minimal tightening of the screws is required when BridgeMagic© is used as a preventative measure. Further tightening of the screws will reduce

    bellying and bridge lift.

*Please note:

If bellying has occurred, it is advisable to tighten the screws slowly to allow time for the guitar top to ‘accept’ the new forces acting upon it.

It is advisable to look into the guitar to check the screws on each side are being tightened evenly and that the BridgeMagic© is remaining level, and not tilting.

In severe cases of bellying, tightening of the screws can be done in increments over days if necessary.

Final note: Assuming the guitar neck angle is correct, and the top has been brought down to near flat, the string height can be lowered further by reducing the saddle.
