Woaouh ! I just replaced my M&B 6L6's with a pair of TAD 6L6 WGC and the difference is simply stunning !It's like a new amp,super sensitive,warm cleans and beautiful breack up... :D I was not completely satisfied with my new set of Mules (too bright/clean and almost single coil or acoustic) but with the TAD,it's beautiful now.But i hear a little bit of microphonics (some "ringing"with some bass notes),if it stays like that ,it's not a problem,though.Is it normal or is it a sign that it will not last long?I hope it's nothing serious because i like them very much !

For the Mules,should i change the height? :?:
