Impressively powerful, and conveniently compact, the Line 6 HX One fits effortlessly onto any pedalboard, and seamlessly into any existing rig. With an intuitive control surface, this pedal offers players over 250 effects taken from HX Series processors, a unique Flux Controller, a jack for connecting external expression pedals and switches, adjustable input impedance, MIDI functionality, and the option of true or buffered DSP bypass. Behavioral Modeling - By measuring the individual components of analog effects devices, HX Modeling technology faithfully captures their unique character and quirks, resulting in immersive and authentic recreations of even famously hard-to-model effects like germanium fuzz and bucket brigade analog delay circuits. Ultra Compact - HX One integrates seamlessly into your rig - fitting effortlessly onto almost any pedalboard thanks to it's ultra-compact enclosure. Interaction - Choosing and engaging effects is a breeze, and adjusting parameters is as simple as using the three corresponding knobs to tweak the values shown on the OLED display. Flux Controller - Flux gives you the ability to simultaneously adjust several effect values over a predetermined amount of time with a single press of the footswitch. Adjustable Input Impedance - A pedal's input impedance is the governing factor over how much the tone of your instrument's pickup is impeded, which changes the tone and response of your playing. With adjustable input impedance, you can compensate for a large range of pickup types. External Control - Connect an external expression pedal (sold separately), two assignable external footswitches, or one of each for even deeper remote control capabilities. MIDI Capabilities - Thanks to MIDI IN and OUT/THRU connections, HX One is capable of receiving program changes, continuous controller, and other MIDI commands from external sources. Bypass Options - Select between True or Buffered DSP bypass - True bypass routs analog signals directly from the input, straight to the output - avoiding A/D/A conversion, and keeping your signal pristine. USB - Perform firmware updates, and backup and restore the 128 in-built presets via USB-C connection to your computer with the free HX One Librarian app. DC Power - Because HX One can be powered with the included 9V power supply or with most third-party power supplies, adding it to your existing pedalboard is a breeze.
