Very Nice tubes
I first tried this tube in Marshall JCM2000 DSL 100 , on the clean channel the tube produced warm creamy bottom end , full mids and bell like tones in the highs like an old Wurlitzer juke box if you've ever had the pleasure of hearing one. On the overdrive channels however , the punch was not quite there and overall the tone was a little fuzzy , I don't know what the gain factor is could be less than 100. I then tried the tube in a Marshall VS100 combo, hybrid , In my experience long plate tubes give hybrid amps the thunder they were meant to produced . Well needless to say , the tubes new home is in the Marshall Valvestate 100 , it completely changed the sound of the amp , the bottom end is pure thunder. the overdrive channels roar like a lion on steroids , press in the scoop and deep buttons on the amp and watch the house shake. I love it. in the right application these are very nice tubes , they would probably sound really great in a Fender Amp.

Great Mullards
Mullard 12AX7 Tubes made at their renowned Blackburn plant are without equal for preamp tubes. Sweet open top end, 3-D mids and a firm round bottom end are as good as these tubes get.Verified purchase: Yes

Blackplates have huge tone
These tubes present the full frequency spectrum, unlike many others. It can be difficult to get one without any microphonics, but when you do, it's a keeper!Verified purchase: YesCondition: Pre-owned
