I wanna make some fredrik thordendal / aphex twin ambience landscape type of music, but there are only basic scales added to the Twin Harmony. Sure i can start studying music theory and do it manually, but things would be easier if you could just do harmonies on the spot

So i have made the most mindblowing VH4 preset of all time with my helix stadium, and the tone shaping with this overdrive adds a huge part. I'm trying to replicate the same tone with a physical rig, and i need this exact kind of overdrive pedal. Anyone knows? According to google it's this Klon® Centaur pedal. But instead of tone knob it says treble. Is the Helix Minotaur overdrive tone knob really just treble?

Yes the sound is slightly louder when it's not connected to the guitar. Anyway i have tested with different power cable and it's the same issue. No matter where i face the guitar it's still making the noise. It's so weird i have never had this issue before until now. Same house, nothing changed. Maybe after owning it for over a decade now it has had enough

I think you misunderstood the amp thing. If i use a physical cab and a real amp i'm not getting that sound (no helix connected). I have also tested connecting Helix to a physical cab and i still get that high pitch noise as well. So it is the Helix unit itself that is making the noise. I will order a new power cable and test if that's the issue though

Helix Floor

No. Just one jack cable, headphones and power is plugged into the Helix

I have tried with muliple guitars, but i still get that high pitch sound that sounds like it goes in waves. I have tried with a physical cab and an amp and i don't get that sound when i do that. So it's something to do with the Helix. It's honestly not playable for me. I have tried resetting the Helix, but that didn't work. I have tried different cables. The ground loop button on the helix doesn't remove the sound either rapidsave.com_why_do_i_get_this_high_pitched_background_noise-t38ukoeumu2g1.mp4
