Mesa Boogie Tube SPAX 12AX7

Jag använder röret med min VOX Bulldog dist samt har det också i min Mesa Rectifier och det ger väldigt bra resultat. Kan inte jämföra med andra som Telefunken eller Sovtek eftersom har aldrig använt dem med effekten men är mycket nöjd med SPAX. Det ljudet är väldigt "tjock" och "köttigt", har mycket attack och boost som är väldigt viktig för disten. Samtidigt det går också bra att mjuka upp den för att få blues överdrive eller något likt, så röret har mycket stor omfattning i ljudet. Kan inte säga om det kan ersätta vilken dist som helst men för de som spelar Heavy Metal passar perfekt. Samt priset är absolut acceptabelt.

These tubes are just unbelievable. I used it to replace the preamp tube on my Marshall valvestate 8240 stereo. I replaced the original one with a JJ tesla tube a while ago and it was good, I liked it, but it is nothing compared to these. The sound is thick, warm with massive low end. It sounds very solid, consistent. I don't really know how to describe it. Well I love Metallica and metal music though I don't always play that kind of music. I think this is the closest to THAT sound I have ever heard my amp when you turn on the distortion. When you turn it up is when you can hear the massive difference there is no loss of tone all harmonics are there...

I have owned this amp for more than ten years and It never sounded like this. I was a bit sceptical about the price at first because I thought they were all the same and it was just all about electronics. I also read some reviews saying that Mesa tubes are just JJ tesla tubes with a printed Mesa Logo... well all I can say is that I recommend these tubes 100%

cold, bright, empty, dark , hollow, unpleasent, sceptic dead sound, I ve tried this with various amps. Great colour with Engl, Peavey, Mesa amps. Quite cold and unpersonal touch when used with more clasic amps like VOX, Fender, .....
This walve has its own metal armour shielding around , ao its well suitable for big heads with big Watts as well :)

For me ? Tung Sol products fits better my needs. More colour, more worm, more thick......iven in dropped B ;)
