So, I just moved to a new college and got to know a few friends who play guitar as well.

Something weird that they told me. They told me that you're not supposed to plug your guitar into the amp while the amp is turned on. They said it can damage the amp/guitar.

What the heck? Is he really right? I've never heard of that. They told me that the buzz that you hear when you're plugging the instrument cable to the guitar, that's what damages the amp. Is this really true?

no. it only hurts the amp if its really loud. than it might blow the speaker.

I dont think it damages it. But i never plug in after i've turned on. If i change guitars, i use the standby switch.

Only tubes amp, though... right?

And that "popping" noise can blow the tubes also, can't it?

No it will not hurt your amp, even if it is turned up loud. That sound will not damage your speaker. It may damage your ears (or the ears of your audience) which is the reason why you should turn your amp down or off before plugging in. If you have a tube amp use the standby switch.

i dont see why it would. but it MIGHT if you have the volume rediciliously loud. if your at practice volume its not going to do anything besides make a really annoying sound.

Actually, people have tested this and it seams to be true. Just like how you should always flick your standby switch on a tube amp while changing guitars.

EDIT-

And to the guy who asked if it can damage tubes, the answer is actually yes. That popping noise that it makes can cause a tube(s) to blow.

So...

Conclusion = it does damage the amp?

Btw, my amp is a modelling amp if it matters.

Can it maybe. I change guitars on my tube amp without using the standby switch. But I dont have it cranked. If you have a pedal tuner switching it so no signal is passed when switching guitars would fix the problem.
