I've recently purchased my first rack mount rig and it's a little over my head. I have a tuner, Behringer multi effects unit and a Hartke 1000w head. I am currently juri-rigging the system to run from the front inputs, but ultimately want to connect the entire system from the back. I can't rack my brain around everything. My last setup was old 70s-80s analog with foot pedals. I'm not well versed in the ins, outs, thru's. Please, any help would be appreciated. Thanks all.
