  1. Hey Line 6-ers, I've been using the Four Cable Method (4CM) for a few years now with my POD HD500 and a Blackstar HT Stage 60 amp. It's been quite successful, albeit after some very careful tweaking. I've posted a video with the results on my youtube channel if you would like to view it for some context: Click Here Essentially it details a disparity between the "Guitar In" jack and the "FX Send" jack. With all things in the signal chain being set to Unity - no FX blocks and Amp Mods on Bypass - The level coming out of the FX Send jack is -2.8dB LOWER, on average, than the source signal. I tested this with a signal generator, recording the level over time, averaging it out. Then putting that signal through the POD HD500 and out the FX Send jack, recording the level over time, averaging it out - and you see the -2.8dB difference. This is consistent across any of the settings for the FX Loop Level (STOMP/LINE) meaning that the issue is not related to that level - it's internal. About 2 years after I did this in-depth analysis - I haven't seen any changes in the firmware that fixed this quirk, but I did start playing with the FX Loop Level switch and the Unbalanced Out switch - which don't make any sense to me. My questions to the Line 6 Folks: 1 - Is the 2.8dB DROP from Guitar In to FX Send deliberate - or is it a bug? Or is it because I'm using a TS cable to go to ONE amp instead of a TRS->TRS cable? 2 - Can you help me (all of us) make heads or tails of the STOMP/LINE/AMP settings with Unbalanced Out, and FX Loop - the only number actually given is the LINE level for the Unbalanced out. From what I've read of the manual: Unbalaced Out: AMP = +4dBv (this is assumed because the only number given is the LINE setting of -10dBv) LINE = -10dBv FX Loop: LINE = +4dBv (this is assumed because the manual says "higher peak-to-peak voltage, making it optimal for Line-level devices") STOMP = -10dBv (this is assumed because LINE was assumed as the +4dBV) I HAVE to be reading this incorrectly - does higher peak-to-peak voltage mean -10dBv? - why would the 2 LINE settings be different? I do know that BOTH -10dBv and +4dBv are LINE-Level, one is for Pro audio application, and the other for Consumer application. Should all 3 of my levels be set consistently? (All at -10 or all at +4?) Currently, my setup is as follows: Unbalanced Out set to AMP(+4dBv), FX Loop set to STOMP(-10dBv), and my amps loop is set to -10dBv. The Result is Loud and clear sound from the amp - but it can be a little noisy, lots of digital background white noise (probably due to dirty power in my old house - so, not faulting L6 for that.)...I can barely turn it up past 2 or it's blowing my ears out. So that means that my amp and the FX Loop are both running at -10dBv, but that the FX Return on my amp is getting a +4dBv from the Unbalanced out of the POD. If I change the Amp's FX Loop to +4dBv - very subtle change, if any at all...hardly noticeable, same thing if I change the LINE/STOMP FX Loop on the POD HD. HOWEVER if I change the Unbalanced Out on the POD HD to LINE, my volume drops significantly and the gain doubles...my clean amp channel sounds like a dimed AC30. I'm hoping this Real-World example is a helpful analysis for everyone - I'm stoked about my setup and it's super easy to gig with - This is more of an intellectual exercise for fellow nerds like me. Rock.
