I used v1.07 of the updater, and I upgraded to the v1.77 drivers before starting the update process. cheers.

yes, the sustainor's bypass, rhythm, and treble boost functions will work with a typical on-off footswitch, so the ext amp will work. cheers,

I backed up my presets using 1.03, performed the update, and then restored using 1.04 with no issues. I did perform a global reset before I restored my setlists so that I could capture any factory preset changes associated with the "US Double" sag parameter bug fix (if there were any). I know it's probably just a placebo effect, but my patches sound and feel better after this (and every other) update. â˜ºï¸ cheers.

you can select the output block and then adjust the "pan" control to the left to increase the volume to your powered speaker and reduce the volume going to the PA. cheers.

I believe you can configure a pedal to send MIDI via the "Command Center" in the global menu. Cheers.

On both the DT25 and DT50 amps, the class A operational mode is lower wattage than the class AB mode. Here is an excerpt from the Sweetwater Tech Tip blog (http://www.sweetwater.com/insync/class-vs-class-ab-guitar-amps/) that summarizes the differences between class A and AB amplifiers. Cheers!

Yes, the feature was added for the HD500(X) and HD Pro(X) in the Variax / Workbench HD v2.10 update back in April of 2014. This suggestion is already on Ideascale at http://line6.ideascale.com/a/dtd/JTV-Variax-Workbench-HD-using-Helix-VDI-as-interface/789597-23508. Cheers.

from the specifications listed on the Dynacord website, it lists the speaker as ... "DCX 12300, 12-inch/1.75-inch 2-way coaxial transducer with lightweight neodymium compression driver" with a 1.6k crossover frequency. It doesn't have a horn, but it does have a coaxial high frequency driver. This would be similar to the XiTone cabs.

2 x Atomic Amps "Neo" Wedges (XLR) 1 x DT25 112 combo (AES/EBU) 1 x DT50 112 combo (AES/EBU) Mesa-Boogie Triaxis/2:90 (4cm) I'm still experimenting with making them all work together, but individually they sound fantastic. The wedges are getting the most attention because they sound great and are basically plug-n-play. I'm still waiting on better DT / Link6 firmware support before spending too much time integrating the combos into my "dream rig". ☺

He cruised by my place today, but no Helix. :( Not to worry because he did leave something for me .... :D

Thanks for the heads up! I just did the same as you and it is shipping tomorrow. :)

On 10/6 when it was "supposed" to ship the date changed to 10/16. Then (yesterday) on 10/7 the date moved to 10/17. Now today (10/8) the date has changed to 10/18. Do you see any pattern here? :( still waiting ....

But you can still install it and access the "Helix Application Pilot's Guide" from the help menu. :)

After my Sweetwater rep said I'd have to wait until Thanksgiving, I ordered mine from MF on 9/24 and was told that I made it into their first group. They also gave me a $120 discount ($1379.99). ☺

My Sweetwater rep said they expect their second shipment "around Thanksgiving". :(

woohoo! thanks for the update.

I had the same issue about 10 weeks moderate playing. I replaced the power tubes and my amp has been rock solid ever since. Cheers.

I started to experience screeching and poping with my DT25 after 10 weeks of moderate use (approx. 50 - 60 hours total). I didn't have time to wait for new tubes via mail order, so I went to my local GC and picked up a matched pair of Groove Tubes (model = GT-EL84-S "medium", part # = 555-0113-580, performance rating = 5). The bias readings for both tubes were 23.5mV and 23.7mV respectively. Both of those readings were within the recommended range (25mV +/-3mV), but I adjusted the bias so that both tubes read exactly 25.0mv. Here is a link to a thread in the old Line6 forums with details on how to check and adjust the bias on a DT25 head. http://line6.com/supportarchivenew/thread/75238 Great suggestion!

Yes, a single footswitch with a standard mono tip-sleeve 1/4" cable will toggle the DT between channel A and channel B. With a dual footswitch using a stereo 1/4" cable, tip-sleeve controls the channel while ring-sleeve controls reverb. I tested the DT25 channel switching feature using a Morley RFS-1 "on/off" footswitch. When the switch is closed (i.e. tip connected to sleeve ground), the amp will use channel A. When open (no connection between tip and sleeve) the amp will switch to channel B. The two external switch outputs on the Octa-Swtich are programmable per patch to be either open (channel A) or closed (channel B ). Thus, selecting the first bank on the Octa-Swtich repeatedly will stay on the channel configured for that bank. The second external switch output could then be used to control the DT25 reverb. Sounds like a pretty cool setup. Hope to hear back on how it works out for you when you decide to pull the trigger. :) Cheers.

You are correct. There is no need to bias pre-amp tubes. Cheers.

I think you also need to remove the screws in the handle.

google is your friend. took less than 10 seconds to locate the following... http://line6.com/supportarchivenew/thread/71626 I replaced the tubes in my DT25 a few months back and found the biasing procedure to be fairly straightforward, completing the process in about 30 minutes. the hardest part was removing the amp from the cabinet so I could reach the bias pots and measurement contacts. cheers.

I believe the green tubing has a 1/4" diameter and the black tubing has a 1/2" diameter. The tubing is fairly inexpensive, so I recommend you get an assortment of sizes and experiment with what works best for your method of assembly. I use the hot-air "wand" from my SMD rework station set to 215 degrees C to shrink the tubing, but any hot-air gun should work. Cheers.

Just a follow-up to my previous post with the reason I believe this additional strain relief is beneficial. Underneath that very cool braided sheath lies a stranded, PVC insulated cat-5E Ethernet cable. It's good that the individual conductors are stranded, since stranded cables usually offer better flexibility than solid conductors. Additionally, the RJ45 terminators have a more flexible and complete connection to stranded wires than solid wire. However, the cable's PVC outer insulator is susceptible to permanent deformation (stretching) every time the cable is forced to bend sharply near either connector. The additional strain relief afforded by the heat shrink tubing helps to distribute any applied force over a larger area, effectively reducing the potential for damage. The Neutric etherCON RJ45 connectors do include a small strain relief "boot", but IMHO it is not sufficient for a guitar cable application. For context, most Ethernet patch cables are used to connect devices that do not move around that much, if at all. Thus, the use of PVC is justified for network cabling as it helps keep costs low. On the other hand, a guitar cable is plugged, unplugged, wrapped, and unwrapped over and over during its lifetime. Additionally, most guitarists are not what I would consider "stationary" objects. Most standard guitar cables use some type of rubber-like insulator that resists permanent deformation, but still utilize heat shrink tubing near each 1/4" jack for added durability. Again, this is just my opinion and not intended as any type of criticism. Hopefully the community will find my suggestion and explanation useful. Cheers.

I have made a few of these VDI cables and recommend that you add some structual strain relief using some inexpensive heat shrink tubing. This substantially improves the durability of the cable without adding significant cost or effort. Just my $0.02. Cheers.
