The Groove Tubes 12AX7 Mullard reissue was instigated by Aspen Pittman with Groove Tubes following the Mullard design and production techniques meticulously. Groove Tubes used the Triple mica design of the original which reduces microphonics. They have followed the famous ladder plate design and the Mullard welding process which gave this valve that famous Mullard stability.

More importantly, sonically they made an absolute classic; they made a valve that has the dynamics and the bite of the originals.
This valve has a super midrange warmth and clarity but what sets this valve apart from all the other current production is it has that bite and when pushed produces that instant CLAPTON Bluesbreaker tone. These ECC83 really kick, install these and you will not be disappointed.
