Turn your guitar away from the amp's speakers. The pickups on the guitar are feeding the amp's signal back into the amp creating a feedback loop, especially with the gain button on. Loud volumes cause this looping path between the amp speakers and guitar pickups. You may need to reduce amp volume also.
Sounds like a bad power supply filter cap...the buzz you're hearing is the 60 cycles hum that filter caps reduce or (hopefully) eliminate altogether. It may also be related to the tubes but finding the bad one will require some work. Any friends have this same amp? If so, try swapping one tube at a time and see if you get lucky. If this amp is new take it back ASAP as it is a manufacturing defect.
Hi. My name is Danielle and I have a peavey rockmaster GT-5 guitar mini amp, and it can work with/without the cable. I lost the cable and I didn't need to worry because the amp still worked as long as it had good batteries. But, after about 4 months of no use of it, I put in a brand new battery and the light wouldn't turn on. I looked all over the amp to see if something was missing but I found nothing. I'm really not sure what to do because this is a very good amp and I'd hate to throw it away. Can anyone Help Me?
The amp is doing what is called "motorboating". This is usually caused when the voltages to sensitive preamp stages are inadequately filtered or regulated and the sudden load of the output stages cause a dip in the voltages sent to the preamps which in turn vary the input to the output stages starting the cycle over. This will require electronic troubleshooting and if your not skilled in that, then it is NOT a DIY fix. What you are seeing is NOT normal, there is a defect.
PLUG YOUR LEAD INTO AMP TURN UP JUST A LITTLE SEE IF IT BUZZES WHEN YOU TOUCH THE END OF YOUR CABLE.IF IT BUZZES THEN THE FAULT IS IN YOUR GUITAR MOST LIKELY THE ACTIVE WIRE HAS COME OFF THE INTERNAL GUITAR PLUG.
