Before You Begin


Warning
WARNING!!!!
The connectors and cable can be easily damaged during installation.
Make sure you understand the proper handling procedures before continuing.


Cable Connector Latch PositionsCable Connector Latch Positions


Alert
Make sure you understand the connector latch positions. The same connectors are used on both the Saddle-Pickup and the preamp.

Up: Make sure the connector latch is in this position when you are inserting or removing a cable.

Down: This position clamps down on the cable to hold it securely in the connector. Make sure to push the latches down after inserting the cable.



Inserting the Pickup Cable

1. Ensure that the cable is oriented properly. The end labeled “Pickup” must plug into the connector on the pickup. The end labeled “Preamp” must plug into the connector on the preamp. The gold side of the cable end faces the access opening on the preamp and away from the circuit board on the preamp.

2. Ensure that the connector latch is in the open position.

3. Gently insert the cable end into the connector. Do Not force the cable if there is resistance. Gently wiggle the cable until it aligns into the connector. When it is properly aligned, it will require almost no force to insert it.

4. Gently close the latch on the connector.

5. Gently pull on the cable. It will not pull out if properly seated with the latch closed.

Preparation

In this section you will prepare the guitar for the installation of the Sound Hole Mount Replacement System.Remove the original saddle and pickup and set aside for measurements.

  1. If required, remove the pre-existing pickup system.

  2. Ensure that your guitar has the proper end-block hole for the jack

    1. If your guitar already had an end-pin mounted preamp, skip this step.
    2. If your guitar does not have a hole big enough for the jack, please take your instrument to a professional to have this hole drilled. If this is not done properly, it can damage the finish around the jack.


Saddle-Pickup Installation

In this section, you will prepare the guitar bridge for Saddle-Pickup installation. If you have not ordered a pre-shaped Saddle-Pickup, then you will also shape it to fit. Finally, you will install the Saddle-Pickup into the guitar bridge.

Mounting the Sound Hole Controls and Battery Bag

In this section, you will connect the Saddle-Pickup to the preamp and then temporarily mount the preamp in the sound hole to balance the string volumes.

1. Assembling the Cable Guide

A. If your guitar already has a 9v battery bag, skip to Step 2.
B. Find a suitable location to mount the battery bag. We recommend mounting it on the back of the guitar in the upper shoulder where it will be out of sight but easy to reach.
C. Ensure that the Saddle-Pickup cables are out of the way from where you are working inside the guitar.
D. Clean the area so that it is free of dust and oil.
E. Temporarily place a 9v battery in the bag and remove the adhesive liner.
F. Press the battery bag firmly into place using the battery to provide even pressure to the adhesive.
G. Remove the battery.

2. Mounting the Sound Hole Controls

Control Board Mounting Location

Sound Hole Controls from the Front


  1. Ensure that the Saddle-Pickup cables are out of the way from where you will be working inside the guitar.
  2. Locate a suitable mounting position on the Low E side of the guitar for the sound hole controls.
    1. Many guitars have a brace near the edge of the sound hole. The controls can be mounted on the brace as long as at least half of the adhesive tape is stuck to it (See photo).
    2. Make sure to pay attention to both ergonomics and the appearance. You don’t want the controls to stick so far into the sound hole that they are clearly visible, but you also don’t want them to be recessed so much that they are hard to access while playing.
    3. Ensure that there are no braces that will obstruct the cable going to the preamp.
    4. The adhesive is extremely strong, and the controls will be very difficult to remove once they are stuck in place. Make sure you are happy with the location before proceeding.
  3. Clean the area so that it is free of dust and oil.
  4. Remove the adhesive liner from the sound hole control board and firmly press it into place.


Adjusting the String Balance

In this section, you will connect the Saddle-Pickup to the preamp and then temporarily mount the preamp on the top of the guitar to balance the string volumes and adjust the mid contour.

B. CAREFULLY insert the 1-3 cable through the slot in the Preamp Strain Relief, then insert the 4-6 cable through the other slot in the Preamp Strain Relief.
C. Ensure that the latches on the preamp connectors are up.
D. CAREFULLY insert the 1-3 cable into the preamp connector marked “1-3” and push the latch down.
E. CAREFULLY insert the 4-6 cable into the preamp connector marked “4-6” and push the latch down.
F. CAREFULLY slide the strain relief onto the end of the preamp until it friction fits in place.

4. Mounting the preamp in the preamp holder

Balancing Mount Setup

  1. Remove the strap button, small nut, and small washer from the jack and mount the preamp in the jack holder.
  2. Reinstall the small washer and nut onto the jack and tighten until the preamp does not spin in the mount.
  3. Plug the pickup system into an amplifier.
    Tap the Saddle-Pickup to make sure it is working.
    Listen to make sure there is no noise or hum. If there is, follow these troubleshooting steps.
    Unplug the pickup system from the amplifier.
  4. Re-string the guitar and tune.
  5. If required, tape the cables to the edge of the sound hole so they do not interfere with the strings.

5. Balancing the Strings

A. Plug the guitar into an amplifier and make sure the amplifier EQ is set flat and the volume is at a reasonable level.
Warning
Make sure the Mic volume is OFF
B. Play a chromatic scale starting on the low E string and note any strings that sound louder than the others.
C. Adjust the loud strings down until they are more balanced.
D. Play a chromatic scale starting on the low E string and note any strings that seem to be quieter than the others.
E. Adjust the quiet strings up until they are more balanced.
F. Repeat Steps B through E until you are satisfied.
G. Play chords, arpeggios, scales, and songs to ensure the guitar response is accurate. Take as much time as you need to get the results you want.

6. Adjusting the Mid-Contour

A. Once you are satisfied with the string balance, adjust the Mid Contour adjustment until the mid-frequency sound from the amplifier sounds the same as the acoustic mid-frequency sound.
B. If needed, repeat the string balancing process above.


Final Installation

In this section, you will remove the preamp from the balancing mount and install it into its final location. Then you will secure the cables inside the guitar body.

1. Removing the String Balancing Mount

Pulling the Preamp into Place


A. Remove the guitar strings and tape securing the cables to the edge of the sound hole.

B. Carefully pull the Saddle-Pickup cable slack up out of the sound hole and insert a dowel rod through the hole in the guitar end block up to the sound hole.
C. CAREFULLY remove the preamp from the String Balancing Mount making sure not to snag any cables.
D. If the guitar previously had a preamp, set the large nuts on the jack based on their position on the old preamp jack.
E. CAREFULLY lower the preamp into the sound hole and insert the dowel rod into the jack.
F. VERY CAREFULLY lift the flex cables out of the sound hole and keep them under slight tension as you pull the preamp into position (see photo). This will prevent the preamp from snagging on the cables as it goes under the bridge.

2. Tightening the Jack

Jack Shoulder Depth
A. Pull the preamp fully into place.
B. Measure the distance between the shoulder of the jack and the side of the guitar. It should be 1mm. If it is not, push the preamp back to the sound hole and adjust the nut on the barrel of the jack.
C. Pull the preamp back into place and re-measure. 
D. Repeat until the distance is 1mm.
E. Install the nut and washer over the end of the dowel rod and tighten them finger tight on the jack.
F. Insert the big blade on the install tool through the small holes on the jack and use a wrench to tighten the nut.
G. Install the strap button nut.

3. Securing the Battery cable

Inside Clip Locations

  1. Referring to annotation A on the image, locate a suitable location on the High E side of the top for the cable guide.
    1. The location should allow you to push the preamp up to the sound hole without needing to remove the cable guide from its clip.
    2. It should be near the side between the bridge plate and the sound hole.
    3. Make sure the location leaves some slack in the cables.
  2. Clean the area of dust and oil.
  3. Remove the adhesive liner from the clip and stick it into place.
  4. Referring to the annotation B on the image, locate a suitable location on the side for the black plastic control cable mounting clip.
  5. The location should ensure that the cable does not move around and hit the side of the body.
  6. Clean the area of dust and oil.
  7. Remove the adhesive liner from the clip and stick it into place.
  8. Secure the control and battery cables into the clip and squeeze the clip shut.
  9. Re-string the guitar and ensure that all the strings are properly balanced.
