This original plug, made from three-piece* machined parts, was developed from scratch to incorporate a variety of cutting-edge ideas (patent pending) and address the many issues inherent in previous plugs. The plug is made of brass, commonly used by many manufacturers, and phosphor bronze, a new material we have newly adopted. This combination allows for tuning to a variety of sound characteristics. While this is our subjective opinion, the general trend is that the all-brass (BBB model) offers a well-balanced character centered on the midrange, resembling the classic tone of legendary guitar players of the past. The mixed (BPB model) offers a well-balanced character across the entire frequency range, with no extreme highs, lows, or mid-range quirks, and a relatively flat, wide-range character with a slightly more subdued midrange than the all-brass model. The all-phosphor bronze (PPP model) offers an unprecedented wide-range character, with all frequencies clearly brought forward. *The "three-piece" refers to the three components that make up the plug: tip, body, and cap.
