Installation Guide for EPA01 passive volume knob:

Confirm you have the EPS001K pickup installed in your guitar, or have purchased it along with the EPA01 passive volume knob module. Note, earlier Journey instruments pickup modules, which do not have a socket on the back of the cable jack, are not upgradeable. See the graphic below – if there is heat shrink tube around the 3 wires going into the back of the cable jack, then you’ll need to upgrade your piezos to the EPA001K or other module like EP002, EP003, EP004) If the inside of the jack looks like (C) in this graphic, you need to upgrade to the EPA001.
Once you confirm you have the upgradeable pickups, then upgrade very easily in this way:
1. First select the optimal location for your volume knob around the sound hole. Place the volume knob in the area near the sound hole that does not bump into the bracing. This may be slightly off-center, but you want the wheel to be easily accessible using your thumb or finger while the strings are on the guitar.
2. After you determine the volume knob location, then unplug the piezo wires from the back of the guitar plug jack, and plug this back into socket on the volume knob.
3. Insert the male connector coming from the passive volume knob into the back of the pickup jack.
4. Remove the adhesive from the back of the volume knob module and attach it to the soundboard with the volume wheel next to the soundhole.
5. Use the 3M secure clips to secure the lose wire to the side of the guitar so it does not vibrate.
If the connections are solid you should now be good to go.

Installation Guide for JourneyTek® Passive piezo pickups. (EP001K, EP002K, EP003K, EP004K)

Here’s a great video overview and a downloadable PDF document for guidance on how to install our passive piezo pickups. The video demonstrates installation for EP001K – our passive steelstring pickup with German-made piezos. The process is similar for EP002K, EP003K, and EP004K.

Note For Ukulele Piezo Positioning: Most ukuleles have three fan braces as shown in the image below.

Position the two piezo elements of the EP003 pickup on either side of the center brace. Because of the size of most ukulele sound holes and the relative distance to the bridge plate, it is sometimes difficult to position the piezos on the bridge plate at the position (1). Alternatively you can position them in location (2). The attachment process is identical to that shown in the above video, with the exception that you will not be using a jig, but will rather hold the piezo in place with your finger until the glue dries.

FOR 12 STRING GUITARS:

Use the EP001K model and position the piezos in similar positions you would for a standard 6 string. Our piezos are wide enough to pick up the signal of all 12 strings with 3 piezo elements.

FOR CLASSICAL GUITARS AND PINLESS BRIDGES:

If you want to position directly under the saddle, or if you’re working with a pinless bridge, you can search on YouTube for “under bridge pickup instal on pinless bridge” and one of the top results show how you can drill into the saddle slot to use a jig for positioning the piezos on a pinless bridge.

For most classical guitar installations, however, our piezos fit perfectly along the bridge plate for most models, and we recommend you use one of these two configurations based on the spacing of the braces on your guitar.
