Second-hand guitar effects are used pedals or devices that have been previously owned and are being resold. These can include distortion, delay, reverb, and other guitar effects, often found at a more affordable price than new models. Buying second-hand guitar effects provides access to vintage models, discontinued pedals, or well-maintained gear that may offer unique tonal characteristics.

However, checking for any wear, damage, or functional issues before purchasing is important. Many players find great value in second-hand effects, especially if the pedals have been properly maintained or are rare, collectable items.
