You can't ask for much more than Trilogy™, the world's 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, Trilogy™—no 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.

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™—to your desired level.

You'll discover tones and effects you never dreamed of with any other type of pickup system.

Trilogy™… setting a new standard in acoustical-amplification systems.

Trilogy™ is a revolutionary design in acoustic amplification systems. It actually incorporates three separate pickups—plus a preamp—in a single housing. Each of the three pickups is the very best of its type. And… Trilogy™ does not require cutting unsightly, tone-changing holes in your beautiful guitar.

Why is using three pickups in one so important to your sound?

Throughout the history of acoustic-pickup design, there have been three basic types of acoustic pickups. Each design has its merits and flaws, and companies have endlessly attempted to engineer the best tone into each design.

• The magnetic pickup (also called a sound-hole pickup): A magnetic pickup is installed in the sound hole and "picks up" the magnetic responses of the strings—similar to a pickup used on an electric guitar. The pickup's coil windings, pole-piece sizes, and magnet size are all designed to produce the most accurate "acoustic" tone. The magnetic pickup is usually more bass-responsive. The pickup actually receives its response from the magnetic-steel core of bronze or brass acoustic guitar strings. These pickups produce very little feedback and do not require a preamp. Some are portable "pop-ins," and they are the most popular for quick installations and a decent tone.

• The transducer pickup: A transducer pickup senses vibrations. Two types are popular—a stick-on style, which may be placed at different locations on the guitar top, and an under-the-bridge-saddle pickup, installed under the bridge saddle. Unfortunately, with stick-on-type transducers, the response from the top of the guitar will also pick up unwanted nuances, such as finger, pick, and arm noises.

A better system is the under-the-bridge-saddle transducer. This pickup reduces unwanted noises and has good acoustic tone, although the tone is more "trebly" than the magnetic pickup's. This transducer may be used with or without a preamp. Using a preamp will increase the response, and, with tone controls, it can be an excellent choice for a permanent installation.

• The condenser mic: A microphone inside the guitar produces very good acoustic tones. Care must be used, however, because of the possibilities of increased feedback and the inherent proximity effect. Simply put, the proximity effect tends to produce higher levels of bass tones. Furthermore, for superior tone, a condenser mic must be used and driven by a battery-powered preamp.

Enter the patent-pending superior design of the Trilogy™ pickup. Trilogy's outstanding features utilize the very best of all three types of acoustic-amplification devices:

• A superior magnetic pickup—This is an extremely low-noise single coil pickup with individual string adjustments for balanced tone.

• A superb under-the-bridge-saddle transducer pickup—For independent response of each string, this transducer has six individual sensors. The Gold-Plated casing provides a level surface for equal string volume.

• A high-quality condenser mic located inside Trilogy™.

In addition, Trilogy™ offers the following advantages:

• A blender pickup system that does not require cutting any unsightly tone-altering holes in your fine guitar

• Gold-Plated pole pieces, connectors, and end-pin jack

• A preamp system conveniently hidden within the pickup assembly

• Easy installation, with no soldering required (Installation normally takes 30-45 minutes.)

• Easy removal, as all components use plug-style connectors

• Easy-to-reach volume controls for onboard adjustments
