I'm presently practicing thru a Peavey TKO 115 that is about 10 years old. It is a great amp for my garage band practice. It holds out well. But it's up until recently that it's starting to sound a bit distorted.....the bass sound is a bit fuzzy. It's not that drastic but it doesn't sound like it used to. I don't know if the speaker is going or maybe the jack needs to be cleaned or replaced. I leave the amp in my garage where it's relatively cool. Could the recent humid weather have effected it? Any ideas or suggestions? Thanks!!!
