I've recently bought the line 6 pod HD PRO x rackmount processor. I have no knowledge what so ever in hooking this up. I have a Mac and a Windows computer available. Gear: line 6 spider iv HD 150 amp head, 100w crate cab, FBV mkii express pedal. Three instrument cables available, and two speaker cables. I've been searching the web for solutions but nothing has helped me. How can I hook this up, ready to use? Many people have used the 4 cable method; however it doesn't apply to me since my amp has no effects loop, amp head only has L R speaker outs, and a direct/phones Jack. I'm looking to get sound out of my cab, hoping that the processor reads my amp head only as a power amp. I went to samash and guitar center to inquire, the only solution I got was to guitar>Pro x in>unbalanced L>amp head in. I got around however the knobs on the processor AND the amp head were operational, I'm assuming the processor reads the amp head as another pre amp, I don't want this. The sound I get is low, and I have to raise the volume for each and every preset on processor because they all have different volume levels,one preset is much louder than another preset. I feel like this method is not really reliable, I have no idea what to do.
