I just purchased a used TA-30 head. It's from 2011 and suffers from the reverb/effects loops noise issue. I guess the previous owner never bothered to get it fixed. This is a known issue for which they have a fix. But they will not cover the amp because it's out of warranty, even though it is within the range of serial numbers that they deemed eligible for the fix. If I bought a vehicle that qualified for a recall that wasn't address by the previous owner it would still qualify. I realize this isn't a safety issue, but I believed that Mesa would stand behind their products. Very disappointing. I could pay for the fix at a cost of about $150, but then the decent deal I got on the amp is no longer so decent. Am I wrong to think Mesa should cover the fix for a known issue even though the amp is out of warranty?
