Report Review for product Vacuum Tube - 12AT7 / ECC81, JJ Electronics

JJ's are well made tubes, bought this to replace a brand new MESA tube that was micro-phonic right out of the box. It is in a Kustom H5 head, Using the 12at7 instead of the 12ax7 to lessen the gain a little so it was more preamp/pedal friendly.
