Pono MTD vs MTDX?

I suppose it should be the same thing, yet I have to ask cuz I see no reason calling something differently than its proper name.

Is there any difference between Pono MTD / MTDX?

One of them may be older version?

Thanks

Same exact model. It's just that the bass company, MTD (Michael Tobias Design) was gonna sue Pono for that being a model. Mahogany Tenor Deluxe. 3 letters with the same initials, go figure. I probably still have MTD on some listings cause that's what I called it for so long. MTD basses are great, but Warrior basses are the best.
