I was hoping maybe someone could lend me some knowledge. I bought a used line 6 spider valve HD100 with Bogner tubes not long ago. And I am unable to control of the master volume.
I wanted to have more manual control over the amp, but as I have read this amp does not work on a manual operation and only with it's presets.
So I did find a nice preset that fits me, and I was able to tweek it some and save it. But when I want to practice in the home, I am unable to get control of the volume, it goes from to low, to blasting in your face with barely a touch of the master volume. Is this a heard of problem? Is it a problem with the amp? Or a preset?
I'm almost guessing it is a preset, because it seems to not do it all of the time.
