Tech Tips

My Acoustic Matrix pickup is balanced and sounds great, but I?m noticing a hum that sometimes disappears. I can make the hum disappear when I touch the endpin jack. Is this an electronic problem?

A humming pickup is almost never the result of an electronic problem, but rather the result of issues surrounding the installation of the pickup in the saddle slot. The most obvious reason to look for is a tear or rip in the foil wrap of the pickup. This material is the shield of the pickup and when disturbed will cause the pickup to hum. Another reason for hum is a poor fit of the pickup or saddle in the saddle slot. The Acoustic Matrix pickups ground properly when under correct pressure in the saddle slot. Anything than may impede the pickup from being properly compressed in the slot, can be a cause for hum. You should be sure that the pickup drops easily into the saddle slot. It should not be forced in to a tight slot. Also, be sure that the saddle slides easily into the slot while not being too loose. Because the bridge is made of wood, it will expand and contract with regard to humidity levels and temperatures. This movement can affect the pickup and saddle fit, which can result in the hum being intermittent. While this is the most difficult type of hum to correct, with a proper fit of pickup and saddle, it should be a rare occurrence.
