So I have a hartke hydrive 112. Im powering it with an ampeg pb800 ss amp with the cab on the 8 ohm setting. Im playing classic rock with a sometimes heavy handed drummer so I know im probably pushing the cab a bit but ive never heard any farting or distortion from it. But when I kick on the fuzz I soon start to smell that familiar burning electronics (magic smoke) kind of smell after a few minutes. So something somewhere is definitely getting hot. I believe its the speaker itself. Ive noticed it running an octaver too. Ive since removed it from my chain. Is anyone familiar with this phenomenon? I don't want to blow my rig.
