My Golden 50s Strat and TH30.

The backing track doesn't sound like minor chords, they sound like seven chords to me, but I'm listening on a phone so it's a little hard to tell. The notes you play over a Major Blues will differ some what from the notes you play over a minor blues. When you play your solo over a jam track, listen ...

Haven't had any issues with the other tubes, all turned out to be the effects loop (12AT7) JJ tube, it had a loud low hum which one of my friends said was probably due to a short in the tube. My dealer gave me a groove tube as a replacement, it quitened the amp down but I thought I heard some traces...

Mine had a bad hum as well, put a new 12AT7 in and she's nice and quiet now.

Mine did the hum thing as well from day one, changing the 12AT7 tube cleared it right up. Quite as a mouse now, only it has a micro phonic tube now, so more testing and tube changing ahead.
