Trilogy Acoustic Guitar Pickup
Trilogy(TM) incorporates a discrete Class A preamp inside the pickup housing. There's also a volume control for each pickup, along with a master volume control, allowing total control over all pickups, right from your guitar. All of this is on, or inside, Trilogy(TM)-no more drilling unsightly holes in your prized guitar.
Install Trilogy's under-the-bridge-saddle piezo pickup, the Gold-Plated end-pin jack(TM), and the Trilogy(TM) magnetic pickup in the sound hole. Then put the battery holder and battery inside the guitar, connect the mini-jacks, and you're ready to go.
Adjust the master volume to a sound level you think is right. Then raise the volume on each of the three pickups-magnetic soundhole, piezo, and condenser microphone, housed inside the bottom of the Trilogy(TM)-to your desired level. You'll discover tones and effects you never dreamed of with any other type of pickup system.
