Opsætning og installation
Proper installation is crucial for optimal performance. The AMUMU SP31WN offers two main installation components: the soundhole pickup itself and the endpin jack assembly.
1. Pickup Installation (Soundhole)
This method involves securing the pickup directly into the guitar's soundhole.
- Gently slide the pickup into the soundhole, ensuring the "AMUMU" logo faces outwards.
- Position the pickup so that its padded clamps align with the edges of the soundhole.
- Carefully press the sides of the pickup to engage the clamps securely against the soundhole rim. Ensure it is snug but not overly tight to avoid damaging the guitar finish.
- Verify the pickup is stable and does not obstruct string vibration.

2. Endpin Jack Installation (Optional)
For a more permanent and integrated setup, the included 1/4'' female jack can be installed as an endpin jack. This requires drilling and is recommended for experienced users or professional installation.
- Remove the strings from your guitar.
- Drill a 15/32" hole in the endblock of your guitar. Ensure precise measurement and use appropriate tools to avoid damage.
- Remove the existing strap button (if any). Insert the new strap button (part of the jack assembly) into the drilled hole.
- Thread and hand-tighten the strap button to secure the jack.
- Slide the cable holders onto the pickup cable. Remove their adhesive backing and place them as needed inside the guitar to prevent the cable from rattling or banging against the guitar's interior.
- Connect the pickup's 1/8" (3.5mm) male plug to the 1/8" (3.5mm) female input on the endpin jack assembly.

Betjeningsvejledning
The AMUMU SP31WN is a passive pickup, meaning it does not require external power (like batteries) and its output level is determined by the guitar's natural vibrations and your playing dynamics.
- Ensure the pickup is securely installed in the soundhole.
- Connect the 1/4'' female jack (either the attached cable or the installed endpin jack) to your amplifier, mixer, or audio interface using a standard 1/4'' instrument cable (not included).
- Adjust the volume and tone settings on your amplifier or mixing console to achieve your desired sound. Since this is a passive pickup, all amplification and tone shaping will occur externally.
- Begin playing. The pickup will translate the vibrations of your steel strings into an electrical signal.
This pickup is suitable for various applications, including:
- Live performances in clubs or on stage.
- Studio recording sessions.
- Band rehearsals.
- Personal practice with amplifikation.
