A powerful distortion sound close to the modern high gain tube amplifiers. The HEAT BLASTER HBL-3 takes the bold, overtone-rich high-gain tube amp sound of the earlier HBL-2 version to the next level with fatter lows and mids that add even more presence and power. The fast response of the HBL-2 is retained for outstanding articulation. By removing sonic components that can degrade the quality of the presence range while maintaining the most desirable harmonics, the HBL-3 sculpts a rich distortion sound with outstanding projection that won't get buried in an ensemble. The HBL-3 has also been carefully designed to avoid excessive compression that can result in a flat, lifeless sound. The result is tube-amp type sensitivity so that picking nuances are directly and fully expressed in the tone. The HBL-3 is ideal for use with the clean channel of a multi-channel amplifier.
BASS BOOST Boosts the low-frequency range. This function achieves extra low-end impact with humbucking and single-coil pickups.
S.C.T. Circuit In a normal True-Bypass circuit, in bypass mode the audio signal passes through two switch contacts. But in the HBL-3, in bypass mode the audio passes through a single contact, thanks to a single contact true-bypass circuit. The result is much higher sound quality and reliability than that provided by previously existing products. The S.C.T. Circuit now makes it possible to further reduce any change or deterioration in sound quality and gives the feeling that the footswitch circuit is removed entirely from your signal chain.
D.C.G. Circuit Due to the adoption of the new double-contact grounding circuit (D.C.G. Circuit), by inserting a monaural plug into the output jack, the shield (sleeve) of the plug provides two points of contact to the pedal's ground circuit. By increasing the area of the point of contact, it becomes more difficult for a loose connection to occur, and provides the additional advantage of improved sound quality.
Multi-function LED In addition to indicating the pedal's on/off status, the HBL-3 LED provides effective visual battery power monitoring. When the battery voltage drops below 7 volts the LED will become dimmer and begin to go out. The effect will still operate at this voltage, but to ensure optimum performance the battery should be replaced as soon as possible.
