You load a new preset, hit a chord, and it doesn’t sound like the demo. Too bright, too dark, too quiet, or thin. Nothing is broken. A preset is tuned on one guitar, through one set of speakers, at one volume, and yours are different. The good news is that the fix is nearly always one of four things, and they’re worth checking in this order.

1. What you’re playing through

This is the big one. A preset built for a full-range speaker or headphones already includes a speaker cabinet sound. Send that into a real guitar amp and you’re running a cab into a cab, and it turns muddy or boxy.

  • Into a PA, studio monitors, a full-range speaker or headphones: leave the cab or IR block on.
  • Into the front or the effects return of a guitar amp: turn the cab or IR block off, and let your real speaker do that job.

If a preset sounds dull and woolly, check this before you touch the EQ.

2. Your pickups

Single coils and humbuckers send very different signals. A preset built on a bright single-coil guitar can sound thick and over-driven with humbuckers, and one built on humbuckers can sound thin and sharp with single coils.

  • Too much gain or mud with humbuckers: turn the amp’s gain down a little and trim the bass.
  • Too thin or bright with single coils: bring the gain up slightly and take a little off the treble or presence.

Adjust the amp’s own gain and EQ first. They respond the way a real amp does, and small moves go a long way.

3. Levels

Presets are balanced for a typical rig, and yours may be louder or quieter. Volume also changes how tone is heard: the same preset sounds thinner when it’s quiet and fuller when it’s loud.

  • Start with your volume low and bring it up, especially on headphones.
  • Judge the tone at the volume you’ll actually play at. A preset set up quietly at home will be brighter and bigger on stage.
  • Level your presets against each other so that switching between them doesn’t jump in volume.

4. Impulse responses and clones

Some presets rely on extra files: impulse responses (IRs) for the speaker cabinet, or clones on Helix Stadium. If the preset is pointing at a file that isn’t on your device, or at a different one in the same slot, it will sound wrong or thin.

  • Load the pack’s IRs or clones before the presets.
  • Open the preset and check each IR or clone block shows the file it should. If not, pick it and save.
  • IR slot numbers can differ from one unit to the next. When a pack includes an IR guide, it lists which IR each preset expects.

On Helix Stadium there’s one more thing to check with dual-amp presets: phase. It’s covered in our guide to loading presets and clones onto Helix Stadium.

Before you change anything

Save a copy of the preset as it came, and edit the copy. Then you can always go back, and you can compare your version with the original.

Every pack on Guitar Tone Gurus comes with a READ ME that lists what’s in the download and how to load it, so you know which of these apply. Find presets for your rig.
