Thanks for that LMAO
Jordan’s videos are always great. Man that guy can play. That organ sounded awesome. He’s fun to watch live.
I want my guitar to sound like a chain saw running through your living room
Squirels were reduced and uberschalls precence funxtioned like a true uberschall precence knob.
I just started to connect my helix with my bogner helios with the 4 cable method, which works great.
Unfortunately I also experience (as obviously some other users) a loud noise/ hum, when trying to connect the Ext Amp switch to the FT. Sw. Jack to switch the amp channels with the helix.
The noise is so loud that I got scared to destroy something in the helix.
Is there any solution found to this problem, or do I have to use a separate Channel Switch?
Try jimmying up a cable with the ground lifted, see if that helps. If it does you can build or buy one for real.
Thanks! I tried that...the noise is the same! (It's actually much more than a hum...it's a real loud sound/ noise!)
Sounds like a ground loop?
I'm with Frank though, still seems like a ground loop of some sort.
It's not there with everything hooked up except the channel-switch cable, and it is there as soon as you connect that one? But lifting the ground on that one didn't help?
Try removing everything except the channel-switch cable, and adding them back one at a time. Never mind if the signal flow actually does what you want, you're just trying the zero in on the conditions that cause the hum. If one of them increases it a lot, try lifting that one ground.
Are all devices plugged into the same ac circuit? You can also try lifting the ac ground on one or both, but ideally not, both for safety and to make your setup more repeatable in different venues.
Seems like you are right (of course...)... I removed everything except the channel switch, which worked! As soon as I inserted the "Send 1" to the input the noise was back!
the ground lift on the helix doesn't change anything.
Everything is indeed in the same circuit (Helix and Helios)...so I guess I'll have to try around a little bit.
But it seems, no matter how i spread all the cables, at least in my basement I can't use 4 CM and Channel Swichting with the helix at the same time.
I understand the reasoning behind not changing "legacy" amps so that our presets are consistent and we don't have to redo them with every update. On the other hand, if there are improvements that should/could be made I wouldn't mind if they introduced them in one big update.
You wouldn't happen to have your computer connected to the Helix via USB? When I do that my for crap USB port shielding makes it buzz like a bee.
What @Highgain described sounds like a ground loop. Plugging the Helix and/or the amp into something like an Ebtech Hum X might help - I know it has solved ground loop problems for me before. There are also USB ground isolators but they seem to get mixed reviews.
No, the USB is disconnected!
And it‘s more like a jet than a bee
Are the Helix and your amp in the same outlet and not isolated in any way?
Maybe this would work, although I was hoping Not to have to buy more stuff (especially with the risk that it doesn‘t work, and having to Send back all that Equipment)
Then, if this is the only way to go...allright
FWIW I consider these puppies to be pure magic - every time I reconfigure stuff I have one or two handy. (Well, at least the single-box, passive Hum Eliminators.) Takes some moving around to find out where to place them - but they've never failed me.
Not isolated, but tried it in different sockets.
