    Hello! Just wanted to verify your DAW and system for QA. I have looked at the Doom plugin and cannot reproduce what you have described. Testing the parameters I noticed with a sine wave that a higher octave is present when adjusting the octave parameter- similar to that of a proctavia, and with pink/white noise the filter seems to to be functioning as a low pass. These parameters may seem more subtle than expected but are functioning on Window 10 [AAX]Pro Tools/[VST]Cubase.
    Hope this helps!

     I thought I read that the octave control was producing an octave below rather than an octave above. Looks like its working as it should. Thanks for clearing this up.

  2. When I was gigging, I would boost the level slider on the output block. Usually, I would boost 3-5 dBs. Using the Master slider on the amp block will add distortion and may not add much to the overall level. 


    If I'm playing high gain stuff, I also turn the gain down when I am boosting the overall output.



  3. Amp was dropped off at an authorized repair center last week. Repair tech called me to tell me it is finished. The new power tubes have been biased correctly. He told me the amp was biased very high at around 43mv when he got it. After replacing the power tubes, the bias is now at 32.2 mv. Also, one of the preamp tubes was not working right so that was also replaced. I will pick up the amp on Thursday and am confident it will sound great.

    So here it is Nov of 2021 and my DT50 112 suffered the same transformer loss.  I figured I would find one and replace it myself.  Line 6 quit making them. Full compass quit making them. The service center advised that they found a transformer, but not the original and it would have to be converted. Estimate $800 to fix. So basically, I have a 63 Lb. anchor or doorstop. This amp is only approx. 11 years old. Thanks Line 6. I asked if they could give me a discount on  a demo Helix all would be forgiven. They blew me off. Although I will continue to use my POD HD500, I'm going to buy a fender amp in the next couple weeks. I have owned tons of Line 6 amps starting with the AX2.  Unfortunately thats it for me. They lost a loyal customer.

    If you still have your amp, you can get a tranny here.

  5. Thanks. I think I will order a matched quad set of powertubes so I only have to get it biased once. 


    Again, though, I am not talking about noise. It's treble freqs in the guitar sound.

    You are using a 50-Ohm mic cable for the Line 6 Link?

    When was the last time the tubes were changed out?

    Are they the specified tubes and bias (go to a Line 6 authorized service for that)?

    Topology II and IV are the noisier louder ones for that extra crunch people like. Along with

    Class, Triode vs Pentode,... they will all play a part in the noise floor level and distortion level

    of the settings.


    To clarify... I am not talking about noise. I am taking about excessive high end (fizz) in the guitar signal. My original post gives details. This amp is not particularly noisy.


    To answer your questions:


    I am using a Line 6 Link cable.


    I just bought the amp. The previous owner says he never changed the tubes. The preamp tubes are EH with "made in russia" stamped on them. I cannot see the power tubes through the cage well enough to see a brand, but there appears to be a green stamp of some sort on them. 


    As far as topology, the TIGHT (1) setting seems to be an improvement over the other three, which all have excessive treble. Class a and ab,  and pentode/triode all have the issue.

  7. I just bought a DT50 112. I am noticing some serious fizz when using the amp with Helix (I am using L6 Link).


    Right now, I have the PV Panama preamp running into the DT.... fizz city. I would have thought a guitar speaker would remove most of the unwanted high end, but it doesn't. If I place a Hi/Low cut EQ block and set the Hi cut to even as high as 15k, it still makes a big difference in eliminating the fizz. That's a pretty high setting, so there is a lot of very high frequency information coming from the amp. Similar issue with most of the preamps and even full amp models I have tried. 


    At first, I thought the stock L6/Celestion speaker was the issue, but if I use the built-in DT preamps, there is no fizz... the amp sounds as expected.


    I don't mind including a high cut in my Helix chain, but this doesn't seem like normal operation for a combo amp with a guitar speaker. Anyone else notice this? I tried a Google search, but I am not coming up with much.

    Hey guys, thanks so much for the replies so far.  Super helpful.  Attached is the preset I'm using.  Pretty run of the mill except for a lot of reverb as it seems to help me get a nice ambiance/soundstage in my headphones which I'm normally using.  It's trickier to do careful A/B comparisons using my HS7's as my room is a lollipop show with echo and other problems (not to mention I can barely even pick a path to my guitar area through all the kid toys and debris).


    Headphones are Sony MDR7506, very standard, with 1/8" jack and 63ohm impedance.  I have to use a 1/4" adapter, and because of the high impedance, the volume knob on the phones output is very low (like 8:30 o'clock).  I wonder if all of that sets up a situation that is susceptible to noise and audio degradation.  If you guys think that's possible, then I will order/borrow some 1/4" low impedance "studio" phones and try those.


    I did some more A/B comparisons, and I can maybe better describe the change in sound.  Before adding the "Send3" block, I hear a warmer, silkier, more natural sounding tone that has a lot of reverb and a nice soundstage (at least to my ears).  When I add the Send3, I hear a slight digital harshness, a reduction in reverb, and a collapse in the soundstage.  The tone sounds digital, less natural, and the ambiance sort of disappears.


    That ping pong delay is the only one I've found that lessens the sound degradation compared with other delays, although it still causes the problems above.  Maybe the reason I find it most tolerable is that it at least doesn't collapse the soundstage (by design).  But it does sound less natural and more digital for sure.  And the other delays are unusable.


    Please keep the ideas coming - I really want to figure this out and will try any and all troubleshooting steps!!


    Also Helix is 2.92, Floor model, sorry I mis-spoke before.

    Your preset sounds good to me. Everything always sounds harsher to me in headphones. I leaned early on with the Helix to NOT create or edit presets with headphones, because they never sound right when I go back to using speakers. For me, anyway.


    For headphone use, on your amp model, turn down the treble and presence, and turn up the bass. A little goes a long way. This will sound better in your phones, but will sound too dark when you go back to speakers. IME anyway. Good luck.

  9. I just like when they add new models. It's fun to hear what these amps (that I will probably never be able to play with in real life) sound like. Then, after a couple days, the shininess usually wears off and I go back to the Freidman or the Litigator or the Epic.


    I will say, however,  that the second Rev model they released in v2.9 (can't remember if Red or Purple) has pretty much replaced my Badonk when I want that type of distortion.

  10. I was initially bemused when I realized my new Helix didn't have an aux input. The reality is, however,  the Helix is configured perfectly for my workflow.


    I realize not everyone would want my particular practice setup, but I run my Helix directly to my PC via USB, where I can sit in front of stereo monitors (decent computer speakers work just fine, too) and learn new material on guitar.


    I can jamb along to backing tracks on YouTube, learn songs and solos with slow-down software (Transcribe), or just noodle. 


    I have a tiny amp and the Boss Waza headphones I got for Christmas last year if I want to play while watching TV.


    I wouldn't trade my Helix setup for anything, despite no aux input.

  11. This video highlights five great presets from Line 6's preset sharing website -- CustomTone. These are my favorite presets for the week of May 10th. Each preset is demonstrated on its own, as well as in a full band mix. Backing tracks have had the guitars removed. Some slight EQ changes may be necessary to help the guitar sit in the mix of a full band.
