  1. UPDATE: my thought on Path B may be partially wrong. Switching between my 2 patches I felt I had more delay when I had pre-effects in Path A and post in Path B and less delay when viceversa. So I thought that the pod processes Path B before Path A! Now I decided to try a different configuration (even less latency!!!). Instead of using the fx loop return of the pod, I am using its Aux in. Seems strange, but except from a 4db loss (easily corrected adding +4db at the mixer), it has more or less the same noise, but less latency! Then I built my 2 patches, 1) input1:guitar input2:aux with pre-effects in Path A and post in Path B, 2) vice-versa. And also now the tuner works! What did I discover? I have even less latency then when using pod's fx loop return, and solution 1) gives me even less latency then solution 2) Try it, you may be surprised of how responsive will be your pod in 4cm mode now! My thought (I am not 100% sure about that, just wondering...) is that the pod was programmed to process the signals I am using in this sequence: Path A -> Path B -> Fx loop return signal. (seems like line6 programmed the pod giving less priority to the fx loop signal) If true, this may confirm why when I am using fx loop return on Path A I have less latency than using it in Path B! The pod did Path A -> Path B -> Fx loop return -> Path A (4 "steps") , instead of Path A-> Path B -> Fx loop -> Path A -> Path B (5 "steps"). And it may also confirm why I am getting less latency using no Fx loop, and even less when using pre-effects on Path A. pre-effects in B, post in A: pod does Path B->Path A-> Path B (3 "steps") pre-effects in A, post in B: pod does Path A->Path B (2 "steps"). My thoughts on WHY this happens may be wrong, but however, please try it: Guitar -> Guitar in -> path A panned left -> left output -> amp front -> pod aux in -> path B panned right -> right output -> amp return (mixer volumes both at 4db, pod's master at full, output switch on Line.)
  2. two stereo signals=two paths (A,B) , that's what I wrote!
  3. There's one thing that you can hear more than latency, which is noise. Follow my guide (be careful with details on pod switches, levels and cable routing) using e.g. the distortion channel of your amplifier and compare it with the "standard" 4CM method... you will hear less noise. Latency is something I became aware of when I used to play with the pod and then (finally!) bought a real tube amp. Plugging the guitar directly in my amp gives my almost "0" latency which is fantastic since it makes you play more naturally and there's a unique feel because of that "direct" sound, I was never able to achieve with the pod models. Speaking about Path A and Path B latency I am 99% sure about the fact Path B is processed before because: - I hear less latency when I mute path A and more if I mute Path B. - If you follow my method and switch Path A with Path B (then you will have to "cross" the mixer panning, so you don't have to change your cable routing!) I have 2 patches on my pod, one like my guide says, and another one with pre-effects on path A and post-effects on path B, path A panned right and path B panned left. Switching between the two patches I hear less latency with pre-effects on path B, so I suggest you to use that. To me it was a clear evidence that path A is processed after path B. The reason may be that the pod is able of computing a stereo signal (2 mono signals in parallel), but it is not able of computing two stereo singals (the two paths) in parallel! So, feeding path B "before" path A, gives you less latency because, otherwise, it takes the Pod two "cycles" to process your signal! Why is my 4CM method better than the "standard" one? The most important difference is that we are not using the pod's fx loop output, which is very noisy and adds a really noticeable latency (definitely more than the difference between the pathA/B thing.) I did lots and lots of presets, cable routing and it took me a lot of time but the guide I wrote in this post is, to me, the lowest noise, lowest latency mode you can get out from your pod. Try it ;-)
  4. 4CM Low-Latency Low-Noise solution: (previously posted by me on another forum, may be useful for many pod users out there) I found out that the pod's fx loop send introduces more noise and more latency compared to the normal line out of the pod. So I found out a way to reduce both noise and latency introduced by the pod's fx loop when using 4CM, if you don't care about hitting your amp's fx loop with a stereo signal. The basic idea is: pre-amp signal on Right channel (Path B) (with wah, compression, distortion effects) / post-amp signal (with reverb, delay effects) on LEFT channel (Path A). (Do not switch Path A and Path B, otherwise you will get more latency, since the pod processes path B before path A). Now: 1) Set input 1: Variax, input 2: Guitar (using same, this method doesn't work at all, we need discrete signals) 2) Don't put any effect in pre-path. 3) Put every pre-effect (wah,comp,dist..) on PATH B (lower), and pan the mixer full to the right. 4) Put an FX loop block (be careful, it must be TURNED OFF! It works, and doesn't add noise and latency as when it's turned on!) and after it, every post/loop-effect (delay, reverb..) on PATH A (higher), and pan the mixer full to the left. (If you turn on your FX loop block, you will hear more latency! But now you don't need it. That's the first reason why this solution is better than the standard 4CM routing) 5) Cable routing: - Guitar cable in pod's guitar in input - Run a cable from pod's Right line output to your amp's guitar input. - Another cable from your amp's fx loop Send to your pod's fx loop Return. - Last cable from the pod's Left line output to your amp's fx loop Return. 6) To have overall unity gain and less noise as possible, I use: - Pod's master volume to 100% so my guitar sounds like it's directly plugged into my amp - Guitar In switch set to normal - 1/4" Out switch set to amp - Fx loop switch set to Stomp if you want less noise possible and attenuate your amp (I get wonderful sounds at low volume with this on!!!). Set it to Line if you want to have the same volume as the pod was not in the amp's fx loop, but you will have a little more noise. - Mixer settings at +4db for my pre/right signal and 0db for my post/left signal. This is the same as the "normal" 4CM method, but splitted in 2 separate signals (Up=before preamp, Down= after preamp) and gives you the best SNR and the shortest latency you can get out of the pod! The same patch can be used, disconnecting both send and return cables from the amp's fx loop, to have the best signal from the pod when using it just in front of the amp. To use pod's pre and full amp models with the configuration shown before, just set up a patch with input1: guitar, input2: same and an amp block in pre-path position, then pan one of the amp's paths (they're both full stereo paths!) to the left so you will send it to your power amp, remembering that path B gives you less latency also in this case and adjust mixer gain as desired. So the best way to set up a pod model patch when using my 4cm cable routing is: amp pre-path->path A muted, path B fully panned to the left. There's only one little drawback: if you set input1 as I do, you will not be able to use the tuner. What I do is create another patch or tune my guitar with my amp model patches (in which I use input1:guitar, input2: same). Use input settings:"preset" to achieve this. Hope this helps. Paolosev91 Feel free to copy this method on other forums and threads! Since Line6 built a great pedalboard, but with a quiet cheap fx loop, I think that a lot of users will benefit from this.
