Hi folks, being a newby on Helix I dare another question here. I am using the HELIX just as a multi-FX-board and as a control panel for my Marshall JVM410H. I love the amp's sound and would not have another one (as long as the Marshall won't go down. If one day it would do so, I plan to use the HELIX' DI-OUT with an alternative set-list with amp, cabinet etc. directly into the mixer). First step was to control the amp's sounds by MIDI Program change mode which worked absolutely perfectly. No need for the amp's footswitch anymore. :) Second step was using the 4CM in order to put the Wahwah at the beginning of the signal chain and delay etc. after the MARSHALL's pre-amp. I've been watching this video for instructions: https://youtu.be/Wvz3L8bJb1w Well, I've been doing as was said here, but the results were so bad, so that I had to switch back to standard send-/return (3 cables). So, maybe someone can help me with this problem, by answering a few questions: My amp has 2 effect loops, one serial (preamp out, return) and one that can be used in a serial (by putting the mix knob on 100%) or a parallel mode (mix 50%). The latter has the big advantage, that the original signal stays in the amp while the Helix (when its effect mix configured correctly) delivers just the FX signal, while the Marshall mixes the original with the Helix' FX to an optimal sound ... in theory. Now in the tutorial it says, that the amp's SERIAL FX loop should be used. Well ... is that so, that good results can get achieved ONLY with the serial FX loop? I ask, because MARSHALL does explicitely not recommend this, if you are not using hi class studio rack effects. Well, no idea, whether the HELIX qualifies as such ... ;-) I learned, that in the HELIX' preset you have to add a send/return block each. But then, there is a "fx loop" block, too. Is this the same thing as one send with the return block combined? I DID make it work, even in parallel mode by putting the delay's mix to 100% and the amp's return mix to 50%. Sounded great. Problem was: when I chose a Helix' snapshot of the same preset that has no active effects but noise gate (as I do many times for rhythm sound), there is some screeching and loud humming that I cannot explain. Even when I turn the guitars volume to total zero, there is a feedback loop somewhere and I cannot find its cause. So I have no idea, where to search. But like this, you cannot use this setting at all. Anyone any ideas? Sorry, if I repeat some questions for the hundredths time, but the forum's search routine could not find answers to my questions ... I appreciate any help, because I need the Wahwah and the delay. First one sounds crap in Send / Return, second one sounds crap in front of the Marshall ... HEEEELP! :(
