Help - What effect is this?

[MrMeacham]

About 3:35 into this Benny Turner (Freddie Kings younger bro) has a cool bass sound. I don't think it's all EQ. I could use some help figuring it out.

Please suggest the pedal that would help me replicate it.

Thanks in advance

That was ridiculous. No clue what he used, though.

Just sounds like a tube amp to me.
