A powerful distortion sound close to the modern thick high gain tube amplifiers!
The Heat Blaster HBL-4 provides aggressive distortion from classic rock to modern hard rock.
A powerful high gain distortion
The new Heat Blaster HBL-4 became more powerful distortion pedal with rich harmonics.
Its edgy aggressive sound got closer to the high gain tube amp sound while retaining picking nuance vividly.
Bass Boost Switch
Boosts the low-frequency range. This function achieves extra low end impact with humbucking and single-coil pickups.
It's more helpful with single-coil pickups to create tight bottom sound.
Wide dynamic range
Internal circuitry doubles the 9-volt supply voltage to 18 volts, achieving wider dynamic range and more amp-like sound than conventional distortion effects.
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.
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.
In addition to indicating the pedal's on/off status, the HBL-4 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.
