The HL-01 is a high-performance compact distortion unit developed with input from top-level professional musicians the worldwide. It reflects ZOOM's rich expertise with analog circuitry and has many attractive features.

Features:

• Smooth and solid high-gain sound
  • Newly developed analog triple gain circuit is ideal for a wide range of playing styles and applications. From lead guitar to backing, the HL-01 opens up a world of distortion possibilities. Natural and smooth sounding distortion in the all-important midrange creates impressively solid guitar sound.
• 3-band equalizer with superb effectiveness
  • In addition to the BASS and TREBLE controls, the HL-01 features a parametric midrange control whose turnover point can be adjusted. This gives you full control over the most important frequency range for each instrument, letting you stress a characteristic or reduce overlapping ranges. The TREBLE and BASS controls are tuned to allow spot-on adjustments of high-range sparkle and low-end energy.
• Amazing low-noise design
  • Designed from the ground up for optimum performance, the HL-01 uses only strictly
    selected parts. For an effect without built-in noise reduction, the low noise level of the
    HL-01 is truly amazing
• Mechanical switch for true bypass
  • On/off switching is performed using a mechanical foot switch which operates
    smoothly and gives tactile feedback. In the bypass position, the guitar signal is passed
    through without any alteration.
• Sturdy metal chassis
  • The rock-solid case made of aluminum not only looks good, it also can withstand the
    rigors of use on stage or rough handling during transport. Stability is excellent,
    ensuring that the unit will not topple over while in use.
