  1. Sounds to me like the pilot guide is recommending exactly what the sweetwater articles suggest. It's not necessary these days because of the higher quality capacitors but use standby for 5 minutes or less when first warming up the amp and not for anything else. That's pretty much what I've done my whole life. I knew that the standby wasn't for beer breaks and I also knew leaving the amp on and on standby for long periods will burn out tubes. The pilot guide says it's not necessary to go to standby when powering down the amp and I never do this because of the pop you get, especially with older fender models. I just turn it off and then reset the amp to standby for the next warm up. Very informative however, thank you for this post. We all need to know the correct, even though not entirely needed, use of the standby switch.
  2. If you are fronting your DT25 with the HD500 then the patch of the HD500 will select/edit the amp models. However what works best is to select/edit preamps in the HD500 (HD500X) connected via Line 6 Link. This will actually change the physical configuration of the preamp stage of the DT25. This is not modeling but preamp configuration. You are changing what type of amp you have. The only other option I am aware of (besides the promise that the Helix will do this for DT's soon) is to physically turn the knobs and switches on the amp :)
  3. I don't know about turning on the amp with the valves out. I personally would not do that. New, correctly biased valves (tubes) is always a good idea in my opinion. I would start with that. Have a professional install a manufacturers recommended matched pair and a new pre-amp valve as well. I wonder if the main problem is the voltage coming out of the wall. I don't know how stable that is. I personally never plug my DT's into the wall. I have a power conditioner that not only mitigates spikes but is also a voltage regulator to guard against sags or fluctuations in voltage. I would strongly recommend a voltage regulator. Best of luck.
  4. No hidden battery. Take it to a certified Line 6 repair shop.
  5. Man this topic come up a LOT. I have the hd500x. I L6link into my DT 25 or DT 50 depending on the size of the venue. I don’t know anything about the hd400 but the key to fronting the DT amps with the HD floor unit is pre-apm settings and No Cab Sim. Full amp models no good. Using a HD 500x pre-amp I can get the same sond as the stand alone amp. Love this setup. There is a learning curve ( I’m still tweaking patches to songs I’ve been playing through that set up for years) Use only pre-amps and NO CAB SIM give yourself time to learn how to dial it in to your perfection
  6. This comes up again and again. I use the POD HD 500X with the L6 link into either my DT25 or my DT50 depending on the size of the venue. I play a large variety of styles/ genres and need the flexibility of this set up. I have used this set up for 4 years with fantastic results. Here is what I do/ do not do. 1. I only use ONLY pre-amp models with no cab simulated and I usually prefer sm57 off axis. 2. I keep the master on the DT at 60% or above to work the tubes. My volume I adjust with either the channel of the individual patch(this keeps all patches at relatively the same volume) or the master on the POD HD 500x.(This regulates overall volume). 3. L6 link out of the POD 500X into the L6 link in on the DT. I get great amp sounds on all 4 voicings although I will admit I'm more of a Fender and Marshall man than Mesa Boogie Rectifier.
  7. I don't think so. If you use the L6 link I do not think the amp will receive additional inputs. I think the best solution for what you are trying to achieve is to run the Roland GR55 into the HD500X FX returns. You can adjust the returns in each individual patch. Hope this helps
  8. Actually it's a great question. I have been using this set up for between 100-120 shows a year for 3 years now and I love it! It's very interesting to me though that nothing sounds as good to me as going from guitar straight into the amp. However, I use the hd500x pre-amps with no cab simulation plus a handful of effects and it sounds awesome. Not as awesome as straight into the amp, but very close. I have to cover 50+ different artists from different eras and this combination is my ticket. The hd500x with a line 6 link can change the voicings on the dt25. That, in my opinion, is the whole point. I have a patch for every song, and I just go through the set list. From marshall jt45 to fender twin reverb to vox ect. All with the tap of my foot. With that being said, you can disable the amp (set to none) feature in the signal chain of the hd500x and just use effects. Probably best to not use the line 6 link but use 1/4" out into the amp, or maybe even effects loop send return. Everybody has their own individual way of making it work. Best of luck
  9. If someone could enlighten me I would truly be grateful. 1. Do the 3rd party IRs for the Powercab plus affect the sound coming out of the speaker or just the cab sim output? 2. Are the 6 speaker models considered IRs or would they be affecting the output of the speaker plus any 3rd party IR? Thank you in advance for your replies
  10. Sound like a pre-amp tube to me, but no guarantee. I would change and bias all power tubes and replace pre-amp tubes. If this does not remedy the situation take it to an authorized line 6 repair shop. Best of luck.
  11. Not to be rude, and I realize spending additional money sucks, but unless you have the proper diagnostic tools and the proper repair training take this amp to an authorized line 6 repair shop. The functionality, versatility and awesome sound of these amps is in part due to their complexity of inter working components. If changing the tubes (make sure they are matched and learn how to bias them) or replacing the fuse does not solve the problem take it to a professional. Just my personal standard operating procedure. They are awesome amps and well worth getting in tip top operating condition.
  12. I would take it in to an authorized Line 6 repair shop immediately. This does not sound like something I would try to fix myself. Best of luck
  13. I'm not sure that's possible with 1 amp. The HD500X controls all of the parameters of the DT50 but the A/B channel is disabled. (if I'm wrong someone please correct me). With 2 amps you could assign seperate output to each amp, amp A and amp B, then assign a footswitch on the HD500X to toogle between the 2. As for replicating sound, get the sound on the amp without the HD500X and then replicate the settings, gain, bass, mids ect, including voicing A or A/B type and transitor type. Then using a pre-amp setting with no cab simulation replicate these settings on the HD500X. That is the best starting place for replicating the "sound/tone" of the amp. Hope this helps
  14. I'm not 100% sure what you're trying to do. Are you 1. Trying to run the hd500x direct so that it sounds like the DT25, or 2. Trying to run the hd500x linked into the DT25 with a patch that sounds like you are not using the hd500x at all but plugged straight into the amp? Although extremely close, I do not think a modeled sound will ever be exactly the same as going directly into a tube amp. If you want the pure sound of the amp, don't use the hd500x, get an a/b switch and the DT25 is a 2 channel tube amp.
