Experimentation is at the core of musical development. Creating new sounds or even manipulating old ones opens you up to a world of musical possibilities. Harmonizer, pitch shifter, octave and ring modulator effect pedals all have been used to create astoundingly original music. New and interesting effects have paved the way to artists to really show exactly what, with a little help, their guitar can do. Harmonizer pedals allow you to coordinate your chords and notes with ones in perfect harmony. The array of effects that are included in most harmonizers can truly add a unique feel to your arrangement. You guitar can easily sound like a totally different instrument when you try out some of the more exotic effects options. The pitch shifter pedal has a similar harmonic use as the harmonizer but is a little simpler to bring into the mix. The blend feature allows you to choose a note and pair it with whatever pitch you're after and then no matter what you strum, you'll have that pitch singing alongside your guitar in perfect harmony. It adds richness and depth to your tone without much trouble. Octave pedals allow you to go up or down an octave, meaning you can match your note with the same note with a scale above or below. This adds a deep or high tone to your sound like you wouldn't believe. They are extremely useful for solos or even just practicing your arpeggios. Ring modulators offer a full modulation effect. This best can be described as a sort of stuttering or interruption of the sound waves that we hear. The manipulation of sound waves that a ring mod can do allows you to take full advantage of the way your audience hears your instrument. It adds texture and style to your music. Unique pedals such as these give you the tools to craft endless amounts of music. Harmonizer, pitch shifter, octave and ring modulator effect pedals may not be your everyday pedal, but they provide you with the ability to make your sound special. The possibilities are at your feet.
