Gear For sale ?

1) No. Any form of sales activity is prohibited under the posting rules of the forum. This is true for both commercial parties as well as individuals.

2) Depends on where you are I guess. Here in Holland I’d be suggesting another platform. Perhaps there are regional or national facebook groups that let you advertise used gear to the right kind of potential customers (I subscribe to two of those here, one for sound engineers and one for used DJ sound and light equipment).
