Only heard of one person having a problem with it, and that was just the connecting ribbon. I have both the 100T and the Super Bassman 300 and have experienced zero problems, although I must confess to being a little wary of it at first too. Significant benefit in that I put in Winged Cs and did not have to pay for rebiasing. Either way I think any problem would be an easy fix, they would just swap it out with a new component - but as I said, if it was going to be a problem I think we would have heard about it by now.
