All user reviews for the Groove Tubes 12ax7

I have been using it tonight, in lieu of a DD I thought "dead"!
First, I want to explain that I'm posting this comment because we do not really think too little notice on all the gear for us, harmonica ...

I just bought a fender 600 for "blow" in it .. and I found a small lack of power and "grain". Indeed, even the volume pot at 12, I found the sound not saturated, slightly "tainted" but not quite "worked" for my taste.

Bin, the result is more than conclusive! For my little amp sounds a little stronger, a point has more presence, 2 points, including more serious, and above all a put ... its now ... It remains for me to buy an adapter for the impedance to saturate a tad more!
Obviously I would do this choice! Now I wonder what it would also changing the 6V6!? (Currently it is a EHX).
