Effective on feedback to manage the Larsen effect (I don't use the sub function). The Larsen detection function, however, is a bit weak; it really has to be strong to detect it, so when you tease it, you don't really see it. In terms of finish, the case feels solid, the faders seem fragile but if you take care of them I don't see any reason.

The use of the product is not obvious at first, but still satisfying.

works very well thank you

Bon materiel
