Why does my amp buzz on certain notes?
If you hear a ringing sound through the amp, then the tube you are tapping is microphonic and should be replaced. Note: It's normal for tubes to make a “ping” sound when you tap on them; a truly microphonic tube will make a long ringing sound that is often mistaken for feedback.
What causes buzzing on bass amp?
A healthy amp is likely to make some sort of noise when idle. ... Poor quality pedal boards, FX units or even guitars will feed noise into the amp that will be exponentially amplified. If the AC supply is poor or your outlet is not earthed well enough then it can create a humming or buzzing sound.
What causes an amplifier to hum?
