The Line 6 Helix LT brings dual DSP-powered HX modeling, 300+ amp, cab, mic, and effects models, and an onboard expression pedal together in a streamlined floor processor for guitarists and bassists.

Legendary Helix Processing

The dual DSP HX modeling engine recreates amplifier behavior, including power supply ripple and tube sag, for responsive playing dynamics. Load third-party impulse responses (IRs) to further personalize your tone.

Fast and Easy Programming

Touch-sensitive footswitches and a 6.2-inch full-color LCD provide direct access to your sounds. Hands-free Pedal Edit mode lets you adjust block parameters using your feet.

Hands-Free Control

The 12-footswitch interface supports preset and stompbox operation. The built-in expression pedal controls volume, wah, or assigned parameters.

Streamlined I/O

Connect your rig using two mono effects loops or one stereo loop, Variax connectivity, MIDI, and external amp switching. The EXP 2/EXT AMP jack accepts an additional expression pedal or provides external amp switching.
