Hey guys, I'm fairly handy, but don't feel completely confident on how to swap this. I'm sure it's super easy, just wanted some advice/confirmation. I bought an 810 with a single 1/4" jack. I just bought :Jack Plate Dual w/ Speakon and 1/4" Jacks - Product Details Is it as simple as splitting the existing wire into the two new inputs? do they need to piggy back? I feel confident I can do the work, just need to know what wires go where. Sorry if this has been posted before, couldn't find it... Thanks!
