Please follow the handling instructions, which are supplied with the double side adhesive tape. 

We recommend using the tape mount at first. There is a very good chance that you will like it just fine this way. If 
you would like to get a “fatter” and louder tone than tape-mounted, you can carefully remove and re-glue the 
pickups directly with superglue.

Installation Preparation:

You are going to install the system according to the diagrams in this manual.

Place the guitar on a table. Use a blanket to prevent damage to the instrument body.

Loosen the strings. TIP: Spread the strings apart by using a thin cord. Knot one end of the cord to the 3 
low strings at the sound hole. Lead the cord around the back of the guitar and tie it around the 3 high 
strings on the opposite side of the sound hole. Spread strings apart and tighten another knot.

Place the guitar so you can comfortably put your hand into the sound hole and feel the inside  structures 
underneath the bridge with your fingers.

Locate the bracing and check if your guitar has a bridge reinforcement plate. This is a thin wood plate 
usually about 3/4" (about 20mm) wide and about as long as the bridge. It is located underneath the 
bridge. You can feel it with your fingers. If there is no reinforcement plate at all, please follow the 
paragraph: "If your guitar does not have a bridge reinforcement plate" below.

If your guitar does not have a bridge reinforcement plate:    

To make it easier for you to install the transducers without being able to see what you are doing, we advise you to 
use one of the 2 following procedures. Procedure 1 requires the help of a friend; procedure 2 is the more precise 
method:

Procedure 1:

Use the pickup cables as a guide to copy the pickup position from the outside to the inside of the 
instrument. You define this on the top of your guitar. For this procedure it is recommended to have a 
second person around for help.  Note: We are not working inside the guitar yet!

Hold one transducer over the bridge in the desired position between D and A string (center position) and 
lead the cable across the soundhole towards the neck. 

Wrap a piece of tape around this cable as a marker, which lines up with the edge of the sound hole that 
faces the bridge (see fig B). Make sure that the cable is straight and gently taut. 

Do the same procedure with the second center pickup (G and B string) and with the two outer 
transducers.

This gives you a fairly precise definition of where the pickups will be located inside your guitar when the 
tape-marks line up with the edge of the soundhole. During installation the second person should help 
keep the cables on continuous gentle tension.
