    Hello All,

    I own a Peavey combo115 that i bought used a few weeks ago. Up until today i had no problems with it. Last night i was practicing and a loud pop sounded. Then the amp started buzzing/humming. At first i thought the jack on my bass was loose but it wasn`t. I disconnected the bass and turned all the knobs to find the source of the noise. The only thing that i found was when i turned the post gain knob the noise changed volume slightly. I have no idea what is causing this noise,but it`s driving me nuts. If any of you have any advice, i would be ever so grateful to hear it,THANKS!

    It doesn't sound like anything major (as in expensive to fix), maybe a broken connection or a minor component failure. But it's probably something you'd want a competent technician to take care of. At least you're in Meridian, so you can save on shipping!

    A pop followed by hum and buzz sounds like a capacitor failed somewhere in the signal path.

    Unless you're experienced in electronics repair, it's time for a trip to the shop.
