Report Review for product Vacuum Tube - 12AX7 C, Groove Tubes

I put this tube in a Bugera TriRec Infinium 100 watt hand wired all tube head in the V5 position along with a new 12ax7A in V1 and 3, 12ax7Bs in V2, V3, V4
I was not expecting what I heard when I switched to the overdrive channels , OMG !!! it sounds better than my Marshall DSL 100.
OD channel 2 in the modern position sound like a BOSS metal zone , just the channel itself , no peddles , unbelievable , .....I'm impressed.
I put a tube screamer in front of the amp and was blown away .
Good tubes make all the difference in the tone of your amp , this groove tubes 12AX7C will be a go to from now on for this Amp.
