Report Review for product Vacuum Tube - 12AT7 / ECC81, Electro-Harmonix

Out of three 12AT7s, specifically purchased for phase inverter duties in two Fender amps (DRRI and Super Sonic 60 combo), this one is the winner. The other two, a JAN 12at7wc and JJat7, worked fine, just not as clear and strong the EHX. The amps seem to be louder and sound better. Of course, YMMV.

Peace,
