fix it

The Axe-Fx III does not have any . Fix: It is driven from the front panel. Add an FC-6 or FC-12 over FASLINK II—one XLR cable, which also powers the controller.

You are in a different layout . Fix: Layouts are complete sets of footswitch functions and you step between them. Holding a switch usually moves you back.

It is plugged into a line input . Fix: Only Input 1 has the instrument front end. Inputs 2, 3 and 4 are line level.

A ground loop . Fix: Use a Humbuster cable from the quarter-inch output—TRS at the Axe-Fx end, TS at the amp. The wiring is built in. An ordinary cable does not use it.

A ground loop on the XLR side . Fix: Use the ground lift switch on the output.

You are changing presets where scenes would do . Fix: A preset change reloads the grid. Scenes load nothing and switch seamlessly—build song sections as scenes.

The preset is out of CPU . Fix: Fractal let you build what fits rather than capping block types. Replace duplicate blocks with channels—four channels in one block cost far less than four blocks.

The preset was never stored . Fix: An edited indicator lights as soon as you change anything. Press STORE. Changing preset with it lit discards everything, without a prompt.

A missing shunt . Fix: Empty grid slots do not pass signal on their own. Insert a shunt to bridge the gap.

A cable, before anything else . Fix: Most of the time it is a faulty or disconnected cable. Plug headphones straight into the modeler. If the preset sounds fine there, the fault is downstream and nothing on it needs changing.

The path does not reach the output . Fix: A grid can look connected and not be. Check the preset begins with an Input block and ends with an Output block, and that those match the jacks you have cabled. Then change each block to a shunt in turn, leaving the Amp and Cab until last, and listen for where the sound returns.

A modifier is holding a level at zero . Fix: If something is assigned to a volume or level control and the pedal or switch it expects is not plugged in, the level sits wherever that missing controller says, usually at silence. Either remove the modifier, or set the external controller's initial value to 100% instead of 0%.

The preset wants a User Cab you do not have . Fix: Presets you downloaded often reference a cab IR that lives on the author's modeler and not yours. Point the Cab block at a factory cab and the sound comes back.

A cable with a short in it . Fix: Fractal list this first. A brand new or long-trusted cable is often the problem. Swap it before you diagnose anything else.

Something is clipping . Fix: Check whether you are clipping the inputs or the outputs. Clipping that only appears on the loudest notes sounds like a crackle, not distortion.

The preset is over the CPU budget . Fix: Above about 80% the modeler starts running out of room and the artifacts are audible. Remove a block and see whether they stop.

The outputs ship set for consumer line level . Fix: Outputs 1 and 2 ship at −10 dBV for consumer line inputs, which is noticeably quieter than an Axe-Fx II at the same settings. Set Output 1: Output Level and Output 2: Output Level to +4 dBu under SETUP : I/O : Audio.

It has not been calibrated . Fix: Calibrate the pedal on its jack first, so the modeler learns its travel. Until then it can act as a fixed value instead of a sweep.

It is not a TRS cable, or not the right jack . Fix: Expression needs a TRS cable, not a standard guitar lead. A volume pedal is not an expression pedal, even though it has the same socket.

Nothing is assigned to it . Fix: Calibrating the pedal does not connect it to anything. It has to be attached to a parameter with a modifier before it does a job.

The preset it wakes up on is the problem . Fix: Power down, wait five seconds, then power on holding HOME until the boot progress bar first appears. It comes up on an empty initialized preset in location 000, which you can store to any location to overwrite the one causing trouble.

A system setting is the problem . Fix: Power down, wait five seconds, power on holding EDIT until the progress bar appears, then SETUP > Utilities > Reset and run Reset System Parameters. Resetting these never deletes or modifies your presets.

A firmware update went wrong . Fix: Power down, wait five seconds, then power on holding both PAGE LEFT and PAGE RIGHT until the Emergency Utility page appears, and update as normal with Fractal-Bot. This is the emergency boot loader, there so a failed update is recoverable.

Something around the preset changed, not the preset . Fix: A preset is a list of settings, and those settings are interpreted by whatever firmware is running. The usual culprits are a firmware version change, a different guitar, a different amp at the other end, or external controllers sitting at different values than they were. Global Blocks that have since been edited will also change every preset that references them.

Presets do not move freely across the line . Fix: Axe-Fx II, AX8 and FX8 presets do not load on an Axe-Fx III and vice versa. The same amp models are present, so transferring settings by hand generally works, and the older modelers' factory cabs live in the Legacy bank here.

MIDI access was refused for gridleak.app, or the prompt was dismissed . Fix: In Chrome open Settings → Privacy and security → Site settings → MIDI devices, and allow gridleak.app. Reload the page, then connect again.

Axe-Edit III or another app is holding the modeler’s MIDI port . Fix: Quit Axe-Edit III and any DAW or MIDI utility, then connect again.

The browser has no Web MIDI . Fix: Use Chrome or Edge on a desktop computer.

This browser has no Web MIDI, which one-click install uses to reach the Axe-Fx III . Fix: Open this page on a computer in Chrome or Edge, or download the file and import it with Axe-Edit III.

Axe-Edit III holds the USB connection exclusively while it runs . Fix: Quit Axe-Edit III completely, then connect again. Closing its window does not quit the app.

The modeler is off, or the USB cable is not plugged into the computer . Fix: Connect your Axe-Fx III via USB and power it on.

Nothing was picked in the browser prompt . Fix: Click connect again and pick your Axe-Fx III in the browser prompt.

Axe-Edit III is holding the USB connection . Fix: Quit Axe-Edit III if it is running, then connect again.

The preset was sent, but the modeler did not answer the save . Fix: Check the preset on the Axe-Fx III. If it isn’t there, install again with Axe-Edit III quit.

Axe-Edit III was open and refused the write for the modeler . Fix: Quit Axe-Edit III, then install again.

The connection dropped part-way through . Fix: Reconnect the modeler and install again.

One-click install loads the preset into the edit buffer, and nothing is kept until you store it . Fix: Press Store on the Axe-Fx III. Pick a location, then press Enter. Or store it from Axe-Edit III.

The file is damaged or is not a preset for this modeler . Fix: Download the preset for the Axe-Fx III again, then install it.

Another preset is still being sent . Fix: Wait for it to finish, then send the next one.

One-click install isn’t available in this browser or on this device . Fix: Download the .syx preset file. Open Axe-Edit III and connect your Axe-Fx III via USB. Go to Preset → Import Preset → select the .syx file. Save the preset to your desired slot.

The connection or the modeler stopped answering mid-install . Fix: Quit Axe-Edit III, reconnect the Axe-Fx III, then try again.
