Ok so I've noticed MPSA06s wired up base-to-emitter actually clip LESS than 2N5401s. But the MPS clamp at 4v and the 2N5 clamp at 5v. I thought the MPS would be more compressed and gainey, with the most volume drop. But it's the other way around. The MPSA06 sound like 12v zeners even though they clamp at 4v and the 2N5401 (5v) are more compressed and yield a larger volume drop. Is there some other aspect of these things that affects how they clip?

I’ve found the same thing. The MPSA06 clips way less than 5v zeners.

Some folks on SLO Clone measured theirs and seems like the MPS clip at about 11v. So weird.
