levels

Two settings in a global menu decide whether the HX Stomp sounds like the demo or sounds broken. Neither is a tone control.

HX Stomp 3.80
Why this page exists

A thin, quiet, harsh or fizzy sound usually comes down to two settings, and neither is a tone control. One is what you told the box your instrument is. The other is what you told it your speakers are. Get both right and the preset that sounded broken sounds like the demo.

HX Stomp 3.80 Owner's Manual

first, tell it what you plugged the outputs into

Global Settings > Ins/Outs, Knob 2: Output Level. There is one pair of outputs and one setting, so unlike the bigger Helix boxes you pick the destination that matters most. Usually that is whatever the audience hears.

Output Level
The Guitar In of a guitar or bass amp
Inst
The guitar input of a stompbox or another multi-effect
Inst
The instrument-level effects return of an amp—four-cable method, or post effects
Inst
The line-level effects return of a guitar or bass amp
Line
The inputs of a studio rack effect, or a mixer
Line

then tell it what you plugged in

Global Settings > Ins/Outs, Knob 1: Input Level. Set wrong, a hot pickup clips the converter before any modeling happens. That sounds like fizz no EQ will remove.

Input Level
A guitar or bass with passive pickups
Inst
A guitar or bass with very loud active pickups
Inst or Line, by ear
A keyboard, synth, or drum machine
Line

The Input and Output blocks in the chain fill green when a signal is present and red when it is too hot. Red means turn something down before that point. Send and Return blocks carry their own clip indicators too, so you can see whether the loop is the problem.

The rest of it

the effects loop has the same choice

The Send and Return pair is set to Instrument or Line separately from the main outputs: Instrument for stompboxes in the loop, Line for a rack processor, or for using the pair as extra ins and outs.

impedance changes feel before it changes level

The Input block carries an In-Z parameter. A lower value rolls off some highs, drops a little gain and feels softer. A higher value is full-range, hotter and tighter. It loads your pickups the way a real pedal or amp input would, so the same preset can feel different with a fuzz in front of it.

Global EQ is for the room, not the preset

Three parametric bands plus low and high cut, sitting after everything. Use it on the day the backline or the room makes every preset too dark or too bright. Fix a single sound in its preset instead.

watch the block levels too

Every block has its own Level parameter, and Line 6's advice is to leave it at 0.0 dB on most of them. Nudge three or four in a row and the output can clip while each setting still looks reasonable.

If it still sounds wrong

Levels are half of it. The other half is the cab block: on into anything full-range, off into anything that ends in a real guitar speaker. With both right, little else can make it sound broken.

Rig setup—cabling and the cab block, per rig

real amps, each read from its schematic, ready for your HX Stomp.
