INSTRUMENT IN (front)
TS, 1/4"front panel
The front-panel instrument jack, on Fractal's Secret Sauce III circuit.
- Worth knowing
- Only live when INPUT 1 LEFT SELECT is set to FRONT in the I/O menu. Plugging in is not enough.
Before anything else
Input 1, and the Humbuster cable
Input 1 is the instrument input and carries Fractal's “Secret Sauce” circuitry, tuned for guitar and bass pickups. The other inputs are line level and will take a guitar, but without that front end. Plug the guitar into Input 1.
FM9 Owner's ManualThe quarter-inch outputs use Fractal's Humbuster wiring, which cancels ground-loop hum when you use a Humbuster cable (a TRS plug at the Fractal end and a TS plug at the amp end). An ordinary guitar cable works, without the hum canceling. If you have hum going into a real amp, this is the first thing to try, before a ground lift or a DI box.
Axe-Fx III Owner's ManualThe front jack needs a menu setting
INPUT 1 LEFT SELECT chooses front or rear. Plugging into the front panel does nothing until it is set to FRONT.

The same wiring as the current generation. A Humbuster cable (TRS at the Axe-Fx, TS at the amp) cancels ground-loop hum.
