Our H90 SideAux adds 2.25″ (57mm) to the side of your H90.
You can pair 2 of them up side-by-side, as the H90 supports up to 6 aux switches!
Please note that our White is way-more-white than the Eventide H90. While we are hunting for alternate tones of white, the aux switch is not a perfect color match. If that bothers you, feel free to ask for a custom color!
