HornFX Review

Interface:  3.5/5
The four knobs on this pedal are all straight forward, however, their effects on your sound may take some experimenting to truly understand.

Noise: 4/5
This is a very quiet compression pedal. It’s tonal properties may be other than what is desired.

Complexity: Simple

Complexity: Simple

Live application: 2/5
Although this pedal is highly regarded, this may not be a great solution for a horn player. There is no real opportunity for subtlety with this pedal. It also tends to affect your tone and make it more stuffy.
