True bypass意思

"True bypass" is a term used in the context of effects pedals, particularly guitar pedals, to describe a circuit that allows the dry, unprocessed signal from an instrument to pass through the pedal when the effect is turned off. In a true bypass pedal, the signal path is completely disconnected from the internal circuitry of the effect when the effect is bypassed, meaning that there is no coloration or alteration of the signal when the effect is not being used.

This is in contrast to pedals that have a buffered bypass, where the signal always passes through some form of circuitry, even when the effect is off. Buffered bypass pedals can help maintain the integrity of the signal, especially in long cable runs or when using multiple pedals, but they can also introduce some change in the tone or feel of the instrument, which some players may not prefer.

True bypass is often sought after by players who want the most transparent and unaltered signal when their effects are bypassed, and it is a common feature in many types of guitar pedals, including distortion pedals, overdrive pedals, and other types of effects.
