Best Bass Envelope Filters

An envelope filter goes by many names, including an Auto wah or perhaps a Q wah pedal, and is a typical effect for both bassists and guitarists. It is best known as what gave disco and funk guitar players of the’ 70s their choppy, electronic vibe. In the bass world, it remains particularly popular with funk players.
As discussed, they’re a set-it-and-forget-it option as opposed to a traditional wah pedal.
Another massive benefit is speed. The circuits within envelope pedals react at a faster rate than we can physically move our feet, making a rapid wah sound possible. This effect is pervasive in funk music.
It’s a bit like driving a manual (stick shift car) versus an automatic. Driving a stick shift gives you more ‘control,’ but do you need that control? Perhaps your attention is better placed elsewhere (i.e., on your guitar playing or singing). Don’t think for a minute that they’ll ‘dumb down’ your sound – the range control makes them very responsive, so the harder you pick, the more wah you get.
The range control adjusts the frequencies affected by the ‘sweep’ effect, meaning you have more of the effect when you’re playing high notes than when you’re playing low notes or vice versa. It can be convenient: you might not want wah on every single note you pick hard.
Sometimes just called ‘filter,’ this lets you choose between a low-pass, high-pass or band-pass. Closely related, the resonance control lets you adjust the feedback of the filter. This allows you to set certain frequencies to amplify more than other frequencies.
Some pedals include an attack control/ response, which controls how quickly the sweep peaks. A fast attack and a slower decay will provide a clear, rhythmic sound. Slower attacks can make your playing sound out of time, and decays which are too fast can also detract from the rhythm of your playing.
