Installation Guide
Step 1: Prepare the Sensor
The wooden piezo sensor is designed to fit snugly into the eye of your instrument's bridge. Ensure the bridge slot is wide enough to accommodate the sensor without forcing it. If necessary, a small amount of material can be carefully removed from the bridge slot using fine-grit sandpaper (400-grit recommended) to achieve a perfect fit. Protect the instrument's varnish with cardboard during this process.

Step 2: Attach the Jack Housing
The ebony, cork-lined jack housing attaches to the side of your instrument. Loosen the adjustable barrel clamps on the jack housing. Position the housing below the waist of the 4th (G) string side of the violin/viola. Gently tighten the barrel clamps until the housing is securely fastened to the instrument's body. The cork lining protects the instrument's finish.

Step 3: Connect the Sensor to the Jack Housing
Carefully route the thin cable from the piezo sensor to the input jack on the housing. Plug the sensor's mini-jack into the designated input on the jack housing. Ensure the cable is not under tension and does not interfere with playing.

Operation
Once the VV-3 pickup is installed, connect a standard 1/4" instrument cable from the jack housing to your amplifier, audio interface, or effects pedals. The pickup is passive and does not require batteries for operation. Adjust the volume and tone settings on your connected equipment to achieve your desired sound.
Maintenance
- Keep the pickup clean by gently wiping it with a soft, dry cloth.
- Avoid exposing the pickup to extreme temperatures or humidity.
- Regularly check the tightness of the jack housing clamps to ensure a secure fit.
- If removing the pickup, store it in a protective case to prevent damage.
Troubleshooting
- No Sound: Ensure all cable connections are secure and the instrument cable is functioning correctly. Check the volume settings on your amplifier or audio interface.
- Weak Signal: Verify the sensor is properly seated in the bridge and the jack housing clamps are tight. A loose connection can result in a weak signal.
- Distorted Sound: Check the input gain settings on your amplifier or audio interface. Excessive gain can cause distortion.
- Unwanted Noise/Hum: Ensure all cables are properly shielded and away from power sources. Try a different instrument cable or amplifier.
