I play through a Hartke LH1000 and the 410 hydride cab. One day at practice I was setting everything up and when I turned it on, I about blasted everyone out of the room. I found this strange considering the volume was set to 2. Along with that I noticed my tone was a bit off. After some investigation I realized my volume and preamp were doing nothing. Everything set to zero and I was still blasting away at great volume. Turns out everything is running directly from my bass, volume and tone. I can't get the tone I once had since I can no longer dial anything in and setting the volume is a huge pain because I have to adjust it solely on my bass and even the slightest adjustment causes a huge shift in volume. Everything is setup the way it has been for a year, everything is hooked up correctly, but for some reason it is bypassing everything on the amp and hasn't changed since. Has anyone ever had anything like this happen or would anyone have a reasonable explanations was to why this is happening? I wasn't able to find anything similar to this issue but hopefully the solution isn't too costly and will be a quick, easy fix.
