Hello all! well i just bought a line6 podhd500 because i heard nothing but great things about it. after buying this thing i've probly never been so frustrated in my life trying to figure out how something works lol. i've only been playing guitar for 3 years and just now forming a band with a few friends, which is going pretty good. the problem is i've never had any background in audio and i have no clue what to do with this thing. i have a marshall vintage modern 2266c combo 50w tube amp with a stevie ray vaughan sig strat. how do i use this thing with my amp? i've been nothing but reading and keep stumbling upon the 4 cabliung system through the fx loop in my amp? is that the way to go? also it seems every one on this site uses the hd500 through a PA system and not even using an amp? i dont get how that would work. i curenty just have my pod hooked up to my amp through the rightmono 1/4 out and the guitar into the guitar in. ive set up lots of patches with the computer editing program but i cant use any of th HD modeling with my amp cuz it sounds all scratchy and shitty. also i tried to plug in my pod to the pa system of our band, i went to the mixing board via a mic cord through the XLR output and that just sounded horrible. i'm pretty close to just returning this thing because i feel i just dont have the audio background to be using this thing and it seems like a waste of good equiptment to me. it does sound not bad through my amp when i disable the hd modeing and use the pedals affects through my amp. i know its a lot of questions but im sick of reading a 300 page manual, it might as well be in french because i dont understand it. thanks for any input, its very appreciated!!,
