The brain of Helix is Line 6's dual DSP HX modeling engine. Representing a giant leap forward in guitar technology, the HX engine reproduces every minute detail that goes into a great amplifier and effects sound and, just as importantly, its feel. Every single aspect has been taken into account, down to an amplifier's power supply ripple and tube sag, ensuring you receive an ultra-realistic playing feel and experience. The classic bloom and compression of some amps and the powerful punch of others are all faithfully accounted for. And you can also load custom impulse responses to personalize your tone.
