Stuck a couple popsockets and cable organizers to the back of my OP-Z and now it’s more comfortable to hold and doesn’t wobble anymore when playing it on a flat surface. And I can wear it like a harmonica now, I guess?
Hat tip to Hainbach for inspiring me to add some tape along the edges like he did with his OP-1! Makes the corners a little less pointy. The tape keeps the back panel from shifting around too.
