hmmm, davey..let me get back to you on that..
Sykes was a big fan of the MK III Coliseum, but I have read he used C+ amps as well-my Coli has 6 6l6 power tubes-rated at 180 watts, but it hits around 300 watts at clipping!Keith Richards was the first to use these for those big outdoor shows..played two on stage-the amount of gain in these freaks are ungodly,but the cleans are just as stunning-its funny, keef played these, and they were also the studio amp of choice for the metallica boys,esp. hetfield!
