Compression

Compression is a guitar effect that controls dynamic range by reducing the volume of louder notes while bringing up quieter ones, resulting in a more even and sustained signal. By smoothing out peaks and boosting lower-level details, compression helps guitar parts sound more consistent and present in a mix. This effect is commonly used to enhance sustain, tighten rhythm playing, and add clarity to clean tones.

Most compressor pedals feature controls such as threshold or sustain, attack, release, and output level, allowing players to shape how strongly and how quickly the compression responds. Subtle settings can add polish and balance without being obvious, while heavier compression produces a pronounced, squashed effect with long sustain and a distinctive feel. Some compressors also include blend controls, letting players mix compressed and uncompressed signals for greater transparency.

Compression is used across many styles, including country, funk, pop, blues, and rock, where controlled dynamics and articulation are important. It works especially well on clean guitar, arpeggios, and rhythm parts, and can help notes cut through a dense mix. For guitarists seeking improved consistency, sustain, and overall control, compression is a foundational effect that can significantly enhance tone and playability.
