18 months between changes... wow. I've had to change my dt25 tubes 3 or 4 times over the past 3 years. I love these amps but they seem delicate.

Just got a second DT25 and noticed a couple of things. First, it sounds great and works great with the HD500x. My questions: 1. The labels on my new DT25 or more yellow than white (like my other DT25). Is this normal or a problem? Has anyone else had this issue? 2. When I turn on the DT25 and the standby is still on, there is a soft hum. The hum goes away when I turn the standby off and it sounds great. My other DT25 does not have this hum. I have tried this connected to my HD500x and not connected. Just wondering if anyone else had this issue. Thanks.

Thanks for the responses. Jake, I had turned the knobs many times on both the pod and the dt. The tubes must have been very worn because (knock on wood) it is still working.

Just to update... I put new EH EL84s and a new EH 12ax7 in the amp and so far, the problem with the presence (or any knob) jumping went away.

thanks for the response. are you talking about the labeling issue or the presence issue?

Got a hd500x back in 2015. after many hours... i love it. I then got a dt25. I've had some problems with the amp ... from fuses blowing, to tubes going bad... probably put in 4 sets over the last few years. When it works it is great. My latest problem with the amp is the presence (or sometimes the mid) would shoot to about 75% without me doing anything. This happens when I use the AES cable or the XLR cable. I just bought another dt25, partly to see if they would change on a new amp, and to have a backup... (or to look cool on stage by having two amps :)). The first thing I noticed is the presence (or the mid) behaves as it should. It doesn't change by itself. The second thing I noticed is it sounds much better than my old amp with the same settings. I think I may have a tube going bad again in my old amp. Ok, hope you are still reading because here are my questions: 1. The new amp labels that light up (volume, bass, treble, etc.) are yellow, not white like my old amp. Is that the way it is supposed to be or do those lights eventually get dimmer and go out? The amp sounds great and seems to work fine so it really isn't a big deal. 2, I wanted to play through both amps so I hooked them together using the l6 link. On the HD500x I set the l6:Control to Amp1:=AmpA; Amp2=AmpA. It looks like I have to set this for each patch. Is there a way to globally set this, so I don't have to go do this to all my patches? I'd also love to hear if anyone else is using this setup and what variations you guys use. Thanks.

Not to highjack the thread, but are you glad you went the helix route?

If all you want is a boost for your lead, you can add the Studio EQ ... leave the lo and hi gain at 0 (so it doesn't change the sound) and bump the gain up some... I usually set it 6. This works great for me.

Thanks for the response... The mid knob has done this as well.... This has happened with both mic and AES/EBU cable.

Has anyone else had any problem with the presence on the HD "jumping" by itself. I noticed sometimes when using the HD500x hooked to the DT25 with the link cable (can't remember what it's called) that the HD display would change to the amp screen by itself. I finally realize the presence control shoots up to a different setting. This is without me changing anything or stomping on any buttons. This only happens when connected to th eDT25.... When this happens, I will twist the presense knob on the amp and the HD... this normally settles things down for awhile. Anybody else had this happen? Thanks

I used to use the 4 pedal mode (I think that's what it is called... top four button for effects, bottom four for patch change)... however I have changed to the 8 button mode (again the name? sorry... all eight buttons are assigned to an effect)... For the lead boost, i use the EQ pedal and just give it a db boost... nothing else. I also like to use a tube screamer and then tube drive in the same line. I can go from clean (screamer off, drive off) to light crunch (screamer on, drive off) crunchier crunch (screamer off, drive on) and smooth driving lead (screamer on, drive on) ... I can then hit the EQ boost if I need extra volume. I really like this setup. I also like to have two delays, short and long in the same line.. My train is this Vetta Comp -> Throaty Wah -> Tube Screamer -> Tube Drive -> Analog Chorus -> Lux Nrm Pre Amp -> Mixer -> Short delay -> Long Delay I have the pedal set to control the volume of the amp which saves me from adding a volume pedal to the chain.

Seems I remember a post where someone was doing what you want. They assigned the amp to one of the footswitches ... so when the amp is off, you are getting channel b on the amp. They used that to A/B the tones...

I would like to have a quick reference to see all the settings for the patches... print screen could work, but I would have to have 4 screens for each patch... Thanks for the replys!

Yes... this is really needed. they could add it to the edit program. I thought I saw a thread with this along time ago but I can't find it anywhere.

Does anybody know of a way to printout the patches (including the settings) for the HD500x?

Thanks everyone for the responses.... I also noted that when this happens, the display for guitar tuning is weird. About an eight of an inch in the middle of the display is slightly lower than the rest of the display.

This happened with the old firmware version and the new one I just uploaded. I don't think it's patch related, but I really haven't checked that. The funny thing is it never happens at home... (no matter what patch)... it only happens at gigs or for the first time last night at practice. One gig when this happened, the only way I could get the buttons to work was to disconnect the l6 link and use a guitar cable into the DT25 effects return. I will try the knob twisting the next time and see what happens.... I know about power, but could it be power fluctuations? Thanks for the reply's!

I have a HD500x and a DT25 and I absolutely love the sound, flexibility and control of the two of them. However, I sometimes have a problem with the HD500x display switching back and forth between the signal chain and the amp knob controls. Sometimes when this happens, all the foot switches stop working.... sometimes I have to press them several times and then they will work. I don't think the knobs on the DT25 are moving (which would cause the display to change) because they stay the same. I thought it might be the tubes going bad, but I just put new tubes in and got the same behavior. This only happens when using the l6 link to the DT25. I use the HD500x when I play acoustic hooked straight to the PA and have no problems. I was wondering if this has happened to anyone else.... Thanks in advance for any help!
