HX Modeling uses dual-DSP processing to deliver the nuanced character that exists in the original classics, giving you natural bloom, compression, modulation, and honk on some models, as well as intense gain and breakup in others. Not only do HX Models sound and feel real, Helix Floor and Helix Rack processors are comprehensive master controllers for your guitar system, with extensive I/O that provides unprecedented flexibility for studio and stage. Touch-sensitive footswitches, customizable scribble strips, and a large color LCD make the user experience faster and more efficient.
