JLD Bridge Doctor – Screw Mount Version
JLD BRIDGE DOCTOR – SCREW MOUNTED VERSION
How it works:
The JLD Bridge Doctor – this unique device is the solution to one of the most common problems with acoustic guitars; bowing of the soundboard.
The Bridge Doctor consists of four parts; a mounting block, tension rod, a screw and an inlay.
The mounting block has a number of different parts which includes the wooden “finger”, plastic post and the grub screw.
The screw is drilled through the top of the bridge behind the bridge pins. The mounting block is then fixed under the bridge using that screw tightened into the plastic post. The tension rod is then installed between the mounting block and the tail-block of the guitar. The grub screw, inside the mounting block, is then tightened against the tension rod. This added tension, applied by the JLD Bridge Doctor to the bridge, counteracts the pull of the strings and the warpage of the top.
The Screw Mount version requires you to drill a hole through your acoustic guitar’s bridge. The Bridge Doctor supplies an inlay to cover the screw head.
Installing a JLD Bridge Doctor will change the sound of your guitar, primarily because you are attaching something to the underside of the sound-board. The Bridge Doctor affords extra rigidity to the guitar bridge which tends to increase sustain, volume and enhance harmonics. This does however impact the vibration characteristics of the sound-board. The overall effect will differ dependent upon various factors such as the shape and size of the guitar in question and the woods used in its construction.
Don’t over-tighten the Bridge Doctor. Be patient. The wood will take time to settle down and flatten.
You will also need an imperial allen key for adjusting the tension which is not included.
