    I can say that Yes, it is worth investigating. Cut a thin strip of fabric, (i used an old tshirt) and simply lay it in front of the saddles and then GENTLY tuck it underneath so its resting against the wires that come down from the peizos. Cleared up 80% of the noise from the tremolo arm and improved the articulation and tuning stability of the models. I also put foam up at the nut, but didn't really do much for the sound. I will devise a more permanent solution, but for now am really happy with results. JTV 69 tremolo bridge.

    Here’s a video detailing replacing and biasing tubes in the DT-25 combo amp.

    I totally overcame my fear and changed and biased my DT-25 amp. Piece of cake! I made a video and posted it. Replacing and biasing tubes in the DT-25 combo amp.

    Can you comment on the modification of having a bias trim pot and probes mounted on the chassis back? I am seriously wanting to do this. I would pay a tech to do the mod, after which point I would start swapping and biasing tubes myself. I have the DT25 COMBO and the bias pot and test probe location necessitates a chassis removal anyway... Really appreciate any and all info on this.

    I'm assuming the procedure is the same for the dt-50 and the dt25 combo (like mine) Are the parts the same? I will be anxiously awaiting your post. Thanks for your time.

    BTW this is from tech support 1) Keep it correctly bias anyway. The power tubes still have to be correctly referenced. 1a) When swapping tubes, they still have to be correctly biased, so that the reference points are correct. Non-linearity can/will occur, and that leads to a host of distortion related problems. 2) Class-A can "... burns out the tubes faster",... yes, if you drive it harder. In general tube wear is about 12-18 months if you're a continually gigging musician (Class-A or A/B). Class-A runs a little hotter,... has to do the thermal dynamic physics (I won't get into that here) of running signal 360-degrees, as opposed to 180-degrees at a time. 3)"Do the pent/tri settings have any factor in the biasing/tube life? either in A or A/B?"--- No, the switches just engage a different gain loop into the signal path for whatever is called for by those switches. So bias must be maintained for optimum performance. These are hybrid amps, DSP with vacuum tubes amp stage,... they are not designed to be modified. These aren't our grandfather's tube amps like the old days (1950's, 60's and 70's). Use the specified matched set tube types (no JJ's, Mesa's or Groove Tubes, they don't bias the same, they go non-linear too soon). Bias will have to be checked and adjusted whenever you change out the tubes (even if you get a matched octets and change two at a time).

    After gathering u as much info as I could, I'm resigned to go ahead and bias my tubes after very change. but there's no tech guy in my town and so I guess I'll do it myself. Is there a thread on the forums that covers this mod in more detail? I searched but couldn't find anything. Thanks for your time

    I run JTV>VDI>HD500>L6>DT25combo I can control DT amp volume with both the DT master and POD master. I keep the DT master @3 oclock all the time and use the POD master to tweak up and down on a per-room basis.

    In lieu of any modifications to the guitar, I find that rolling up shirt sleeves on your picking arm and wearing a sweatband on your picking wrist cleans up the sound greatly. I'm absolutely amazed at how much noise a shirt cuff can make on those piezos. And lord help you if you wear bracelets or a watch... A pinky ring is like an anvil hammer.

    Hey Sammy, after much tinkering, I admit that your recommendations are for the best. So here's the full rundown on getting a "dry" signal out of one side of the POD Place all FX and Amp block in path A, mixer at the end of the path and pan hard LR Input settings In1=guitar+variax In2=same L6 link settings amp 1 Left place a dummy plug in the left 1/4" POD output, the right 1/4"out gets the dry signal, and the DT gets all your FX and Amp.

    I had been running all patches AB/pent, then I think in a post of yours I read that if you have the DT running Class A all the time that the bias is irrelevant. You say it burns out the tubes faster, but if it saves the hassle of biasing everytime it'd kinda be worth it for a lazy sod like me, doncha think? Tubes are a constant money soak, but so is paying a tech, or buying measurement gear and the time you spend and.... as a guru/expert, could you give an estimate as to the wear ratio between A and A/B? like: A wears twice as fast, or 20 times as fast? or, hopefully, 1.1 times as fast. I'm gonna switch a batch of patches to all class A and see if I like the sound, if so, would this be a harmless workaround of having to bias my power tubes at every swap? Would it put undue heat stress on the amp? Do the pent/tri settings have any factor in the biasing/tube life? I want to settle into a "routine" setup that ensures long life for my amp, with minimal screwdrivin on my part so I'm willing to try whatever. Ideally I could set all patches to class A, never touch the bias pot, buy an octet of matched el84's every year and just plunk 'em in a pair at a time. Please tell me that's an awesome idea. Thank you for your time, everyone. JTV69>VDI>PODHD500>L6>DT25combo

    With new HD500 firmware, it does. All the manuals on Line6 site are for v2 I think v2.1 added mv feature.
  15. jegler
    The link to list of stereo/mono effects is broken. rrrrrrr.

    PS below is an excellent thread on mixer routing on the POD along with a schematic. http://line6.com/support/topic/2033-pod-hd-500-500x-new-routing-schematics/

    Yeah the DT is loud as f*&k when cranked to glory. Hate to recommend spending more money, but get a POD HD500 w/latest firmware and Use the POD's master volume to turn down. You can keep the DT cranked up. It still sounds cooked but at comfy levels. For real. Way better than LVM.

    I'm waiting on this question too
  19. jegler
    This, of course, begs the question as to why Line6 doesn't do that anyway. The DT25's bias pot is mounted so that it is absolutely impossible to get to without entirely removing the chassis which, as I understand it, is screwed and glued in. Fk. At any rate, does anyone have any experience with careless bias settings? I guess I already do - when my DT was shipped, it was suuuuuuper loud. I could barely use it for gigging. The tubes burnt out after about 25 hours of use. sent it back to the factory, when I received it: same deal. I sent it back again with an angry note demanding they triple check the bias of these tubes. Got it back and the amp sounded perfect and the tubes have lasted about 100 hours (they are just now giving hints of wear) Anyway I second mtreehugers "I hope someone who has actual knowledge of what effects there would be throughout the tolerance range of EH matched pairs in the DT can weigh in here and explain it to us definitively. "

    Not yet - still not clear when you say "In the DT settings page I choose only path A" I'm trying to duplicate your settings but am not getting a clean/noFX signal out of either of my 1/4" outputs. In mixer I'm set Vol A = 0 pan 100% Vol B = 0 pan 100% In the POD's utility settings page 3 Input1 = guitar+variax Input2 = same (I normally set to "aux") There's no DT settings page. In POD's utility settings there's L6 settings on page 9&10. Are you messing with those? (they don't seem to do anything for me) Anyway thanks so much for the reply and info
  21. jegler
    I so totally don't want to have to bias my tubes every time they wear out. (I don't have any qualified tech's close by, and the DT25 looks like a major pain to dissemble not to mention the money involved in either case.) Surely it's not that bad to go forth with tubes that are a bit out of whack, yeah? What's the worst that can happen? Seriously, what is the worst that can happen? I understand that even buying matched tubes (as I do) is still a crap shoot as to their tolerances. But big deal, right? Right? I'm kinda freakin out here... There has to be many many users who've plopped in mail-order tubes their whole lives. Or am I the only one? HaaHa, I've done it for years with my old 80's Fender Bassman and never had an issue, but the DT scares the lollipop outta me. Thanks for all the great info everyone.

    DT25 Voicing&Class settings for LongTubeLife Can anyone tell me if the voicing and/or class settings on the DT25 are any harder or easier on the tube life of the amp? That is: if I had every patch play Class A/B Pentode, would that shorten tube life compared to Class A Triode? or viseversa? Does switching back and forth voice/class settings stress the amp or tubes? After getting my amp back from service, my tubes were factory replaced and re-biased, sounded glorious, but tubes are wearing out after <100 hours. I set all patches to Class A/B Pentode and tubes are EH I bought a stash of EH replacement pre's and power tubes. I can just plunk those in and expect to be up and running. Right?
  23. jegler
    Hey, would you mind getting really specific on how you set this up? I want to do the exact same thing. I assume you're connecting to the TC via the 1/4" outs on the POD. I had been connecting to my TC with the FX send, but don't want to eat up an FX block.

    any posts on how to achieve something similar with the JTV tremolo bridge? looks like you may be able to thread a thin, narrow strip of fabric underneath the saddles between the string and the vertical bridge screws. wondered if it was worth investigating...

    Been using oeman's JTV banks for quite a while now and they work great. I'm posting a set of HD500 Patches for use with the DT - Dream Rig. These make use of the 4 voices on the DT and are arranged sequentially (I, II, III, IV) so you step through clean, crunch, dirty, dirtiest. These are leveled for live use and include a volume boost with a 2nd expression pedal. Each patch has noise gate, wah, 2 compressors, 2 distortion boxes, a mod and a delay. Set up for 5-8 viewing. 2 banks of LVM and 2 banks of Pre's are included for a total of 16 patches. If someone would have posted something similar when i first got my dream rig, I could have saved myself like 27 weeks of tinkering... jegler LVM.zip jegler PreAmp.zip
