About the Crossover block

An audio crossover splits the audio signal into frequency ranges, to be processed or amplified separately.

Tips, tricks and troubleshooting

No Global blocks

The Crossover block doesn't support Global blocks.

Bi-amping

Some bass/guitar players split their signal in highs and lows, and send them through different amplifiers. This can be accomplished with the Crossover block. The factory preset PLEXI BI-AMP (Axe-Fx series only) demonstrates this. Or check Leon Todd’s video tutorial: "5 Minute Tones - Distorted Bass"

Alternative approach

There's no Crossover block in the FM3 and VP4. Filters can be used to achieve something similar. See the POLYFUZZ CROSSOVER FM3 factory preset for an example.

Flint tremolo

This forum thread discusses the use of the Crossover block to create a so-called Flint emulation: "The Flint Tremolo Done Right"
