Boss AW-3 Dynamic Wah

Boss AW-3 Dynamic Wah


The AW-3 is meant to be a versatile envelope filter pedal with all kinds of goodies inside. Its real claim to fame is the humanizer effect that is supposed to mimic vowel sounds. This all seems like a lot of fun, but one you start exploring this pedal, you will soon find yourself disappointed. The confusing interface, poor effect quality, and overall frustrating nature of this pedal do not bode well for its use with horns.

InterfaceVersatilityClarity of EffectLive ApplicationTotal Score
Complexity: Simple

Complexity: Simple

Interface: 1/5
This pedal is confusing. It is vaguely labeled and awkwardly laid out. It is not worth the trouble.

Versatility: 3/5
This is a potentially versatile pedal. All of its settings have a lot of promise and seem to be able to give you a nice range of sonic options. The reality is however, that most, if not all of those effects do not work very well and are not useful.

Clarity of Effect: 0.5/5
Most of the effects this pedal produces speak poorly on all wind instruments. The effects are quiet, bodiless, and some seem simply not to work.

Live application: 1/5
Very few of this pedal’s settings are actually usable. Its difficult interface also make it undesirable in a live setting.
