Splitting instruments into 2

Apparently, previously existing instruments before (or just the battle mando?) were nerfed even lower than the new ones, or kept the same if they were already low.

The new ones are now stronger. I.e. new battle mando, 4-10, old ones 60 max -> 1-6...

soo.. Do we split the old ones into something like Battle Mandolin (Pre-Bard) or something?

Just put two different grades...like (Pre-G16S2) and (Bard Rebirth Event).

I will ask to see if my friends existing battle mando changed or stayed.

Wasn't something like this done with the Lightsabers Beam Swords?

Existing mandos changed. I checked my friend's. 1-6 dmg now.

And eh, forget it, I guess. I already changed them all.

Beam swords are different because they all coexist at the same time. The new instruments are meant to replace the old ones, but the old ones do still exist, but now unnaturally.
