These are well constructed tubes for the price. Good solid glass, nice looking innards, and thick pins.

Despite their price, I really like these - lots of clarity and detail and just the right amount of gain. They aren't overly gainy.

Noise or microphonics have never been an issue for me. I have had a few go bad - perhaps 1 in 20.

Overall this is my choice for a good clear 12ax7 that will give me the good Fender clean and sound like a 12ax7 should.

These give nice headroom and don't get gritty or grainy like the Tung Sol 12ax7.
