Line 6 HX Stomp Settings Guide

The HX Stomp puts the full Helix amp library in a compact 6-block unit. Studio-quality DSP modelling of 300+ amp models and 250+ effects. Common use: 2–3 blocks of amp+cab, remainder for effects.

The best Line 6 HX Stomp settings start with: Amp Gain at 5/10, Amp Bass at 5/10, Amp Mid at 6/10, Amp Treble at 5/10, Amp Presence at 5/10, Amp Master at 6/10. Adjust from there based on your amp, guitar, and room volume. For Blues: Amp Gain 4/10, Amp Bass 5/10, Amp Mid 7/10, Amp Treble 5/10, Amp Presence 4/10, Amp Master 7/10.

What Each Control Does

Input Impedance
1MΩ Auto
Custom
Auto-sets impedance based on the first block in chain. Leave on Auto for most use.
Amp Gain
Clean
Saturated
Drive within the selected amp model. Same behaviour as the physical amp's gain knob.
Amp Bass
Thin
Heavy
Low-frequency character within the amp model. Affects preamp response.
Amp Mid
Scooped
Honky
Midrange presence. Most critical for mix cut-through. Never fully scoop.
Amp Treble
Dark
Bright
Clarity and articulation. Pair with Presence for full high-end control.
Amp Presence
Smooth
Aggressive
Power amp upper-mid resonance. The most underused but most impactful control.
Amp Master
Low
Driven
Virtual power amp saturation. Higher = more compression and bloom from the modelled power tubes.
Cab IR
Off
Custom
Cabinet impulse response. For FRFR/direct: always on. Through a real guitar cab: bypass.
Output Level
Low
Unity
Global output. Set to match your interface or mixer input level.

Settings by Genre

Blues
Amp Gain4
Amp Bass5
Amp Mid7
Amp Treble5
Amp Presence4
Amp Master7

Use Fender Deluxe Reverb or Twin Reverb model. Mid-pushed, low gain. Drive the Master high so the virtual power amp provides saturation. Add a TS808 block before the amp for extra push.

Rock
Amp Gain6
Amp Bass5
Amp Mid6
Amp Treble6
Amp Presence6
Amp Master6

Plexi (Super Lead) or JCM800 model. Moderate settings across the board. The Presence knob makes the difference between warm rock and aggressive classic rock character.

Metal
Amp Gain8
Amp Bass5
Amp Mid5
Amp Treble6
Amp Presence7
Amp Master7

Mesa Dual Rectifier or Friedman BE-100 model. High Gain and Presence. Add a Noise Gate block (pre-amp, threshold -40dB). Keep Mid at 5 to avoid mud — the amp's natural voicing handles the metal character.

Indie / Clean
Amp Gain2
Amp Bass5
Amp Mid5
Amp Treble6
Amp Presence5
Amp Master8

Vox AC30 TB or Matchless DC30 model. Very low Gain, high Master for virtual power amp saturation. The Vox models break up naturally with pick attack at these settings.

Amp Master7

Clean Fender model (BF Deluxe or Twin), mid-pushed, low-to-moderate gain with high Master. This replicates the clean-to-breakup response of a cranked vintage Fender. Pair with a TS808 or Klon block in front.

Thorn (Line 6 artist) uses the HX Stomp for direct recording. British crunch model, balanced settings — he notes that mid-range EQ is the most important variable for mix-ready direct tones.

Tips & Common Mistakes

  • For direct recording: always use the Cab IR block with a quality IR (stock 1024 cab IRs are excellent). The cab IR is as important as the amp model.
  • Running through a real guitar cab: bypass the cab IR block completely. The cab models assume a flat/FRFR playback system.
  • The HX Stomp can run as a guitar interface (USB audio) — 6 blocks of processing + direct monitoring = a complete DAW-free recording setup.
  • The Gain knob interacts with Master: low Gain + high Master = power amp saturation (British feel). High Gain + low Master = preamp saturation (American feel).
  • Limit to 4 blocks maximum if CPU usage becomes a concern. The DSP limit shows as a warning when the chain is too complex.
  • Most amp models have a "Bright" switch parameter hidden in the model's expanded controls — check this before adjusting Treble, as Bright on/off changes the tonal character dramatically.
