Hey guys,

I've had my Spider IV 75W for a little over a year now. I've played nearly everyday. I jam with friends, make cover videos, use the record out features, etc. I've been very happy with it until recently.

THE PROBLEM:

For some odd reason, the low end sound coming from the amp now sounds awful. It's a chunky sound, and rather hard to explain. Sometimes it takes a second for the effect to set in, other times it's there from the second I turn it on. I can hear it on the high gain settings and when everything is completely clean. It still shows up through headphones and when I record out as well.

WHAT I'VE DONE:

As far as troubleshooting goes, I've tried using different guitars (to rule out it being my guitar Amplifier Problem: HELP!. I even replaced the batteries in my pick ups), I've used a new cable, I've reset the amp according to an online procedures guide from this website, and I've used my gear on an identical amp from a store.

I want to think it's a speaker problem, but I can't be for sure. I don't know how to rule out software and other harware problems. A little help identifying the problem would be appreciated. Also, suggestions as to where to go with it, anything else to try, potential costs of repair, etc. would be nice.

Any other information you need to know, please let me know!

Thanks in advance.
