Evolvedmb Posted November 25, 2015 Share Posted November 25, 2015 I have watched almost every video of the Helix on youtube, and have not heard any controllable feedback come from the unit. Users do not let the notes decay long enough with a distorted tone to create the tube amp effect. For early adopters, can you demonstrate with a video or just post a response confirming or denying this topic and feature? I will be using my Helix in a live setting directly going through the board, and my band plays a few songs that require feedback in certain spots. My practice amp (Peavey Vypyr 10 & 30 watt) can emulate feedback, so I'm hoping that a $1,500 unit can also reproduce it as well. Thanks for responding!

thestratmanblues Posted November 25, 2015 Share Posted November 25, 2015 You can emulate the feedback by using:the Twin Harmony block, set the V1 Shift to 8th (octave),assign the Mix to a controler (Exp Pedal or Variax Tone Knob)and make sure the V2 Level is set to 0, just to hear the V1 note only.

duncann Posted November 25, 2015 Share Posted November 25, 2015 For feedback emulation, thestratmanblues outlined about the best way to do this. It's certainly not perfect. In fact, it really has quite a different feel than actual feedback. Instead of the Twin Harmony, you could also use the pitch wham set to an octave higher. And when using the mix control, don't go all the way to 100%, but rather around 60% - 70%. I use this technique on some of my songs (with an HD500X) and it gives a nice blooming effect to a sustained note. You can also add a phaser to the tone to give it a slightly less sterile feel.

phil_m Posted November 25, 2015 Share Posted November 25, 2015 If you're using actual stage monitors that you're close to, you don't really need to emulate feedback. You can produce it just like you can with a guitar amp. Point your pickups at the monitor and squeal away. Of course, it depends on you having adequate volume to do it, but in a typical band scenario, it should still work. Quote Link to comment Share on other sites More sharing options...
gunpointmetal Posted November 25, 2015 Share Posted November 25, 2015 Never had an issue with musical feedback out of a modeler, don't expect this one will be any different. Same principles of amp feedback apply: volume + proximity + no noise gates = musical feedback Quote Link to comment Share on other sites More sharing options...
JonnyPM Posted November 25, 2015 Share Posted November 25, 2015 A simple thing I do is use the Ubersonic (or other high output amp) and a distortion block with the expression pedal controlling the gain of the distortion. Toe down and gain at 10, it will feedback all day long. Toe up it brings the gain level down to normal distortion level, 2.2 in my case. I use that method for the Possum Kingdom solo (if you can call it a solo) and can keep the feedback coming for as long as the bassist wants to keep going with the bass riff. I can control how much it feeds back with the Expression pedal. Quote Link to comment Share on other sites More sharing options...
Evolvedmb Posted November 25, 2015 Author Share Posted November 25, 2015 Thanks for replying!!! I'm really looking forward to finally getting my hands on the unit and creating some killer tones. Quote Link to comment Share on other sites More sharing options...
