How do you reduce distortion?

Minimising Distortion Ideally, you would want to measure the signal level at as many points as possible, using a VU (Volume Unit) meter or similar device. Generally speaking, you should keep the level below about 0dBu at every point in the pathway. If you can't measure the signal level, you'll have to do some deducing.

What is the effect of distortion?

Distortion and overdrive are forms of audio signal processing used to alter the sound of amplified electric musical instruments, usually by increasing their gain, producing a "fuzzy", "growling", or "gritty" tone.

How do you reduce amp distortion?
