My friend has a Super Lead 100 MKII that I just recapped and put back to stock. It's been probably a decade since I've owned a Super Lead. I notice that when I turn up the volume on the bright channel and the Treble or Midrange, I get a bunch of pink noise, even with no guitar connected. Is that normal for these things? Otherwise, it sounds great.

[@ChesapeakeRepair]

Hi! Not sure what pink noise is but all tube amps make some noises when turned up. It just depends. Hard to say without hearing it in real life. Sorry I know that’s not very helpful!

[@6AM_YT]

@@ChesapeakeRepair Like a hissy sound.

76 is not the first Marshall went to circuit board

[@ChesapeakeRepair]

You are totally right. I’m not sure why I wrote that. Thanks!
