    My son is interested in installing an analog VU meter in the body of his electric guitar. We've found this link which describes simple and more complex ways of connecting a VU meter.

    He's looking for an effect only, not necessarily an accurate measurement. We were considering a 3K9Ω resistor and a 33μF capacitor, with Schottky diodes. Is it indeed this simple for his purpose?

    He would be well advised to use an LED string for a VU meter with a LM3914 chip as driver. An actual mechanical analog meter will not like the kind of banging around it would get attached to a guitar.

    Yes, I agree. And he could use green, yellow and red LED's arranged in an arc for a neat effect.

    After reading your replies, he may just install them as dummies for that retro look. He salvaged them from an old cassette recorder bought at the Salvation Army for $2
