Russian valves. Dont buy that china junk

I just pulled the stock JJ from mine and cycled about 5 vintage 12ax7 tubes I have kicking around until finallynarrowing down to 1. The difference in tone was drastic and the difference in volume was very surprising. I didn't think that changing the preamp tube would increase volume at all! Maybe the JJ that was in was tired. I'll have to put it on my tube tester and see. Anyway, this little beast has really come alive. It for sure doesn't sound like my Superlead but will definitely do the job if it happened to break down.

I've got a vintage Telefunken preamp tube in mine. It's probably worth more than the Amp but it has given me more of that vintage Orange tone from like the late 60s to early 70s. I'm digging it. Great to have hundreds of old school tubes in my collection for rolling tubes

I am thinking of trying 12ay7 or 5751 to lower the gain. I mostly use these amps as clean as possible. I am stuck at 9 O'clock. I am thinking lowering it will increase the range of clean tones.

The MESA BOOGIE Tubes Just RULES!!!!!

JJ tubes all the way for me

this amp have a rever?

JJ and EHX sound really nice.

What a triffic test eh Rodders !!!

I had a buddy years back who had one and we did a smart test. Not as many tubes and had the same result with the EHX 12ax7 so we left that in his amp! Just made the amp a beast!

Cool. This video was made about the time I bought my Micro Terror - That Electroharmonics tube is HOT! I just ordered the Mesa Boogie - It was my pick from this bunch. I trust their quality.

anyone know who mesa's current preamp tube manufacturer is? I understand they switch factories from time to time.

I'm kind of leaning towards the JJ's pretty loud compared to the others

WHEN YOU DO THIS YOU DON'T NEED ADJUSTMENT OF BIAS?

WICH IS THE ORIGINAL STOCK TUBE? EH AND MESSA INCREASE THE VOLUME AND LOW END TO ME

I put in a Tungsol Au7. More usable cleans. No significant loss of vol. Tonal character a bit smoother than the original JJ, but essentially the same. I like it. Just gives me a bit more headroom.

Gostei mais da JJ !

Cool Demo! Thanks for that! Ist funny to see how less is inside after the case is replaced

Thank you,

Fabulous demo. Thank you so much. You save me hours and a lot money. I liked the louder EH and Mesa tubes.

what was your personal favorite??

Some sound like ring modulation wtf

Very interesting! I like so much your good Idea of testing differents tubes.

Which valve would you recommend to make my micro terror more fender-amp like? Thanks for the video!

Really helpful video.

I like The Amp Dr Ax7. Switched to the in some of my amps.

tungsol making it quieter? wtf
