Hi there,
I recently bought an AD20 from gloco in the Yard (+t again to him for the perfect transaction!), and when the unit arrived to me noticed there is not a standard one.
First of all, it does have some gorgeous knobs which are much better than the original ones:
In the other side, it does have an additional mini xlr 3 pin plug.
I asked George about this and he doesn't know what's exactly this.
Any ideas about what could be this used for? If it was an input for mini xlr plugs, should this have to be 2 inputs (for full stereo sound?)
