Common Effect Settings

Parameters

This is a list of the most commonly used settings found across various effects in the Line 6 Helix, Helix Rack, Helix LT, HX Stomp, HX Stomp XL, and HX Effect.

Drive

Adjusts the amount of overdrive, distortion, or fuzz.

Bass

Adjusts the bass level.

Mid

Adjusts the midrange level.

Treble

Adjusts the treble level.

Speed

Adjusts the speed of the effect, with higher settings providing faster rates. Press the knob to toggle between Hz and note values. Choosing a Hz value provides a specific modulation speed in cycles per second; choosing a note value provides a time based on the current tempo. Not all Speed parameters can be synced to note values, as they may be non-linear and highly interactive.

Rate

Adjusts the rate of the effect, with higher settings providing faster rates. Press the knob to toggle between numeric and note values. Not all Rate parameters can be synced to note values, as they may be non-linear and highly interactive.

Time

Adjusts the delay/repeat time, with higher settings providing longer delays. Press the knob to toggle between ms and note values. Choosing a ms value provides a specific time in milliseconds; choosing a Note Division value provides a time based on the current tempo. With a note division value, this parameter's value is retained when changing models.

Scale

Delay models with multiple taps have a Scale parameter for each tap, which adjusts its time relative to the main Time value. For example, if the Time parameter is set to 500ms, setting the T1 Scale to "50%" will mean that tap will be at 250ms. If you then adjust the Time parameter, the timing of all the taps will scale accordingly.

Depth

Adjusts the intensity of the modulation. Higher settings result in more extreme pitch bending, wobble, or throb depending on the effect.

Feedback

Adjusts the amount of delayed signal fedback into the effect. Higher settings can provide more dramatic textures.

Decay

Sets the length of time the reverb effect sustains.

Predelay

Determines the time before the reverb effect is heard.

Spread

Spread differs slightly among stereo delay effects. For most delays, it adjusts how widely the repeats bounce left and right. For example, with the Ping Pong Delay, 0 is in the middle (mono), and 10 is full left to right panning for the repeats.

For modulated stereo delays, Spread affects the LFOs’ (low frequency oscillators) stereo modulation behavior. At 0, the LFOs are in sync. At 10, the two LFOs are 180 degrees out of sync, so that when one side is modulating up, the other side is modulating down.

Headroom

Some mod and delay pedals' internal signal paths exhibit a bit of grit, especially when placed after a high-gain amp block. Negative values increase the perceived amount of grit; positive values clean things up a bit. At 0dB, the model behaves like the original pedal.

Low Cut, High Cut

Filters a portion of the block's bass and/or treble frequencies, which can help remove rumble and/or high-end harshness.

Mix

Blends the effected "wet" signal vs. the "dry" signal passed through the block. When set to 0% the path bypasses the effect completely. When set to 100%, the entire path is fed through the effect, and no dry thru signal is heard.

Level

Adjusts the overall output level of the effects block. Be careful not to boost this parameter too high on multiple blocks, as digital clipping could occur. You should typically leave this at 0.0dB for most blocks. Where the original pedal's level or volume knob behavior doesn't really apply to dB values, 0.0-10 may be used.

Trails

Trails Off: Any delay repeats or reverb decays are instantly muted when the block is bypassed.

Trails On: Any delay repeats or reverb decays continue to decay naturally when the block is bypassed or a different snapshot is selected.
