You can't ask for much more than Trilogy, the worlds most advanced acoustical reproduction pickup system ever. Trilogy, a patent-pending design, incorporates three pickups in one unit, which is the housing that goes into the sound hole.
Trilogy 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, Trilogyno more drilling unsightly holes in your prized guitar.
Install Trilogy's under-the-bridge-saddle piezo pickup, the Gold-Plated end-pin jack, and the Trilogy 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.
