7/30/2019 method for mount GK-3B

http://slidepdf.com/reader/full/method-for-mount-gk-3b 1/8

This method is for an electric bass (4-string) that has

sufficient space for the controller on the front.

 

Measure the distance between strings.

Measure the distance between the strings of the bass. You can easily measure this by placing the

gauge that is printed on the GK-3B package, under the strings. In this example, the distance

 between strings is 19 mm.

 

Adjust the divided pickup.

Adjust the divided pickup in accordance with the distance between strings. First, loosen the screw

on the side of the pickup.

Move the marker so it matches the string intervals, then re-tighten the screw. The marker position is

16mm at the innermost side and 19mm at the outermost. For this bass, the string interval is 19mm

so you should align it to the outermost side.

There are two markers. Adjust both markers identically.

Determine the pickup installation position.

Position the two markers directly under the G and E strings (on this bass, these are first and fourth

strings) and position the pickup so it is within 50mm of the bridge bearings. Use tape to mark these

 positions.

Adjust the height of the pickup.

Put the spacer under the pickup and adjust the height. There are three types of spacer: a 3mm, a

1mm, and a 0.25mm type. With the protective paper of the spacers still on, try various combinations

and adjust so that the interval between the strings and pickup is 1.5mm when the strings on the

highest fret are pressed down.

 Note: Since the thickness of the spacer's two-sided tape is 0.1mm, keep that in mind when

determining the number of spacers

Verify the fourth string using the same method.

•When the height of the first string and fourth string differs, adjust by cutting and affixing theincluded pickup cushion or spacer. Adjust in the same way when the bass body is curved

rather than flat.

Secure the pickup to the body.

Remove the strings and affix the spacers.

 Affix the pickup onto the spacers, applying sufficient pressure to secure it.

Verify the installation.

Check once more to verify that there is no problem with the position and height.

Adjust the pickup cable length.

Temporarily position the controller where you will be installing it on the body and see how much

excess pickup cable there is.

 

Place the excess pickup cable into the back of the controller.

Install the controller.

Remove the three screws from the back of the controller and use them to secure the controller to

Holder A.

Press Holder A onto the edge of the bass body. On the rear side place Holder B so the assembly is

secured with the bass body in between.

Secure Holder A and Holder B by tightening the 5 x 20mm cap bolt.

Finished!

This method is for a bass with a small body or one with

more than four strings that does not have enough room

to install the controller on the front of the body.

 

Pickup installation.

Install the divided pickup following the same procedure used for normal installation.

 

Holder A and B installation

Place Holder A and Holder B so that the body is in between them, and secure by tightening the 5 x

20mm cap bolt. When doing so, Holder B should be on the front of the body and Holder A should

 be at the rear of the bass.

Install the controller.

Remove the three screws from the back of the controller and use them to secure the controller to

Holder C.

 

Using the two 5 x 8mm cap bolts, secure Holder C to Holder A.

Adjust the height of Holder C so the rear of Holder C does not contact the bass strings. Place it over 

the bridge and secure. A controller cushion for affixing to the rear of Holder C is also included. Use

it as necessary.

Secure the cable.

Affix the cord hook to the side of the bridge to secure the pickup cable so it does not get in the way

when playing.

Finished!
