Here is a basic patch I was playing with tonight: https://drive.google.com/file/d/0B3jebYiMqFtFNE55Ul82TmdqY1E/view?usp=sharing I was still unable to get the noise down to the same level as when the Helix is completely out of the chain. If I turn on the noise gate right after the FX Loop, it cuts the sound out, but it's there when I'm playing, albeit mostly drowned out by the guitar. I can't help feeling like there shouldn't be that much hiss. It seems like the Helix is bumping the level up louder in the FX Loop than if the signal went straight into the amp. The Ebtech did take away some slight buzz I heard, but not the hiss. I have the input, sends, and output set to instrument level. I did try switching the FX loop to line level at one point, but it didn't seem to do anything except make the whole thing quieter. Global EQ is bypassed. Any help is appreciated!

Thanks everyone for chiming in... evh0u82I have an Ebtech Hum Eliminator sitting around somewhere in a closet. I will try plugging it in to see if it makes a difference. If that doesn't work, is there a particular model you are using. I'm not sure if it is technically an isolation transformer or not. cruisinon2Yes, I absolutely love the amp! It's loud and mean, and up until this point, quiet. There is something exciting about being able to bypass and try out some Helix tones though, so I hope i can get it sorted. DarrellM5I will post a patch when I get back to the pedalboard. It's at the rehearsal space right now. Is there a way to fire up the editor at home and pull the patch off there without the Helix connected? I started it on the computer. It's very basic, so it should be easy to troubleshoot. Thanks, everyone! Chris

Hey All, I am coming to Helix after using an M13 for years. I've never used 4CM or an FX loop before, so I'm hoping for some advice. I am running a Les Paul with DiMarzio Super Distortion pickups into an Orange Dark Terror. I play in a style (as you can imagine) with very high gain as a rule. The Dark Terror is usually sitting around 3 o'clock for both the gain and the scoop, with the main volume set at 1 o'clock. Believe it or not, the amp is not really that noisy. Granted, there is hiss, but it is very manageable. Strangely, after setting up the 4CM with the Helix, I find the DT's preamp block to be very, very noisy. It basically drowns out all the other background noise in the rehearsal space. If I switch to a Helix amp model, the noise goes away. I am using a noise gate as the first block in the Helix chain, but since the preamp is coming after that, there is nothing taming the sound. It seems weird to me to put a gate in after the block, and it really changes the feel of picking as the gate has to open, which is not instant. Basically, with the Orange amp "off" in the Helix, there is no noise. But with it engaged, it is a hissing mess. It still sounds the same when I play it, it's when I'm not playing it that it irritates me. What am I doing wrong? If I bypass the Helix 4CM and plug directly into the amp the noise goes away, and I still get the same tone I am after. When I put the 4CM back into place, everything is fine until I activate the preamp block and then HISSSSSSS. Again, I'd prefer not to have to put a gate in after the I/O block, and when I experimented with a noise gate block tonight it never really completely got rid of the hiss without massively affecting the tone. Any ideas? Things that I think could be affecting it, but I'm not sure: FX loop on the DT just noisy? FX loop on DT is run by a 12AT7, should I try swapping it? I assumed (maybe incorrectly) that like most digital devices, the big volume knob should just be turned up and forgotten about (I'd like to bypass it, actually) - could the Helix be amplifying the hiss? Thanks for any input! Chris
