First, turn down the treble, then adjust the bass. Just like testing gain, try playing your guitar with the treble about three-fourths high and the bass the opposite. Then, move the treble lower and the bass higher until you find the perfect spot that sounds great and has completely stopped the feedback.
People also ask, is feedback bad for a guitar amp?
More likely to damage the speaker, but not all that likely. Tends to heat up the voice coil a little. of course if feedback is coming because of the level the of your guitar is way too high on a crappy, then it could eventually blow, but it should barely do anything.
Regarding this, why does my amp have so much feedback? This feedback occurs because that high-pitched sound is caught in a loop getting amplified and fed back through the guitar over and over again. Most amplifiers have at least a simple EQ built into them. If you can turn down the high frequencies, this will affect this feedback loop.
Also to know is, why is my amp echoing?
Most echoing problems are caused by other strings ringing. By other strings I mean strings that you don’t pluck (strings you don’t play). For example, you play an open A string. Along with the A string ringing, you hear the noise from other strings.
