This is because a regular wah pedal works as a moveable peak in your signal’s EQ, sweeping from a nasally and anaemic tone to a treble-boosted scream. That’s why ‘auto wah’ pedals can be categorised as filter pedals. Filter pedals also work in a fairly similar way to wah pedals too, with a ‘peak’ moving across the frequency spectrum. This isn’t dissimilar to how modulation pedals work in processing a signal, with the LFO adjusting the waveform, in this instance, to manipulate its shape. Most filters will use an LFO (low frequency oscillator), which assists in adding movement to your signal. The result is an effect that can give a vocal-esque quality to your tone, by embellishing notes to produce a variety of vowel-like sounds. However, it doesn’t work like any regular EQ pedal, as an envelope filter dramatically changes the tonal qualities of your guitar signal using additional processing. This is so that we can provide you with a better idea of how to get the most out of them, so you can integrate them successfully into your rig.Īs we said in the introduction, a filter pedal ultimately takes your guitar tone and enhances it by adding (or taking away) certain frequencies. ![]() But first, we’re going to explain all of their details and functions. we have a great selection of these peculiar guitar pedals available. These effects pedals let guitarists transcend the gap between rock and electronic/pop genres, and have even more of a place in the music world than ever before. Further electronic wizardry helps in creating their sound too, and envelope filters are very recognisable to the ear. In fact, with extreme settings they can make your instrument sound like something almost completely different! Essentially boosting frequencies with a moveable sweep, with a filter pedal you can enhance certain areas of your EQ to bring out harmonic overtones for expressive vocal-like timbres. Often overlooked for being too diverse for the bog-standard rock guitarist, filter pedals are used by many modern players that wish to expand their tonal palettes.įilter pedals can totally transform your guitar tone. These are the unsung heroes of the pedal world.
