Lonestar Overdrive Problem

[jjoelson]

Hey guys,

I have a mesa Lonestar which I love and use often, but just today I had a problem with it. When I use the drive, the sound becomes muddy and fuzzy, definitly not what its supposed to sound like. Both channels work fine without drive, but when I turn it on there is obviously something wrong. So I'd like to ask those here who know about these things if this is just as simple as a blown tube or something or if there actually might be a problem with the amp. I hadn't used the amp in a while so I don't really know if it was a sudden problem or something slowly wearing down. Any help would be much appreciated.

definitely check the "drive" tube: "V1"

+1 for checking that preamp tube.

Let us know what you find out?

You guys were right, I replaced the tube in V1 and everything was fine again. Thanks for the help
