Hi,What was the pot value that you put in it. For ceramics and crystals, they're ultra hi-z mics and require a pot with a minimum of 1meg resistance, ideally 5meg and anything lower than that, the change is gonna be really quite drastic. Blues Blasters originally came with 250K pots and then later 500K pots, which is fine for guitars and dynamic mics or mics with CM/CR elements in them.

I just put an MC-151 element into a Blues Blaster mic. [Thanks to the
generosity of a friend on this list]
It works, but I notice a tone change over the range of the volume pot.
Louder is brighter tone, and lower is more muted tone (HF roll off).

It didn't behave this way before. What can I check on next?

Thank you. Any ideas are welcome.
