Detuner

A detuner guitar effect alters the pitch of the signal by a fixed amount, creating harmonized or doubled tones without the movement associated with modulation effects. Unlike chorus or vibrato, which continuously shift pitch over time, a detuner applies a static pitch offset, often just a few cents sharp or flat. This produces a thicker, wider sound that feels stable and polished rather than swirling or warbling.

Detuner effects are commonly used to simulate double-tracked guitars, add subtle stereo width, or create harmonies at specific intervals such as octaves or fifths. Many detuner pedals allow players to blend the dry signal with one or more detuned voices and to route signals in stereo for a broader, more immersive sound. Because the pitch shift is fixed, detuners maintain clarity and tuning accuracy while enhancing fullness.

Guitarists use detuner effects in rock, metal, pop, worship, and ambient music, especially in rigs where width and consistency are important. They work well on clean and driven tones alike and are often placed late in the signal chain to maximize stereo spread. For players looking to add depth, thickness, or harmonized textures without obvious modulation, a detuner is a powerful and precise pitch-based effect.
