Grade of the tube

The physical characteristics of the tubes themselves have a huge impact on how long they can last.

The mode of use is also key because the more you use the mic heavily for long extended periods, the more it is likely to your tubes will last only for limited amount of time.

It’s not all the time that your tubes will just stop working, sometimes you’ll just notice a change in the way that they sound.

This may then force you to purchase a new one.

You’re likely going to encounter the inability of the microphone to respond to frequencies accurately and well enough, once the tubes start to deteriorate.

However, some tube mics can withstand a heavy workload, you just need to find a more premium one.

Brand
