USB Guitar Plug , USB CONDENSER

So I been working to get much better gear and I make the discovery that ,

Their is guitar plugs that end in USB , and then their is CONDENSER MICS that use USB.

So you mean If I can actually make my SANSAMP the last thing in my line up pedals meaning it acts as PREAMP and have that go into the USB ?

So no need for AUDIO INTERFACE then ?

and then Obivously USB CONDENSER just uses the USB PORT .

Apparently there’s an A/D converter built into the USB plug
