If you like the form factor of the Multiswitch, check out GFI System’s Triple Switch. Just keep in mind it connects from the top: https://www.gfisystem.com/triple-switch

I personally use the AUX3AE triple switches from Analog Endeavors: https://www.analogendeavors.com/product/aux3-controller

Saturnworks and America Loopers are other companies making switches for Eventide.
