Hi guys,
im getting a ridiculous amount of hum/interference from the LT when using the 4CBL method into my JVM410h
The helix is wired up the usual way a 4cbl method is, Left/mono into the JVM Return. Helix Send into the JVM input. Helix return into JVM Send
I have a midi cable changing the channels of the helix too snapshot one is the clean channel of the JVM with some effects. snapshot 2 is OD1 Red which just hums uncontrollably, snapshot 3 is OD2 Orange which hums but an acceptable amount for a hi gain tube amp.
Ive got 2 gates active on the preset, one at the guitar input, and one right at the end of the chain, Ive trialed and errored all the blocks bypassing them one by one and none make a blind bit of difference when the amp is on the rhythm channel.
Global settings is everything is set to instrument, anything else and the hum gets louder than the guitar signal its ridiculous.
I tried pasting a YouTube video I made about the whole thing but it doesn't let me post any videos in this thread, so if you want to try and find it the video is called - so much hum from Helix LT and my name on YouTube is - Jesey Floyd
This is the last straw with this unit unfortunately im far too stressed out trying to get it to work properly I can't put more gates on it as it just makes the sound terrible.
Any help is appreciated thanks
