Line6Perry,

Would you please verify the 4 DT50 amp models.

When I select the Treadplate amp in a new patch with my HD500 my DT50 112 automatically configures to:

CLASS A/B

Pentode

Topolgy III

The reference plate that come with the DT50 lists the IV Modern High-Gain as:

Class A/B

Pentode

Topology IV

The only amp model that automatically configures to Topology IV is the Angel F-Ball.

The other 3 amp models you listed:

I: Fender Blackface Deluxe

II: Park 75

III: Vox AC30

appear to match.

Thanks

Hi,

I: Fender Blackface Deluxe

II: Marshall Plexi JTM 45 MKII

III: Vox AC30

IV: MESA Dual Rectifier

Regards,

L6Perry

Edit: NFL II is actually based on the Park 75.

Since I posted my patches for soundalike dt50 thought I'd better post

more accurate patches now that I have it in my head....

Hell you probably did and I didn't follow or something...but i did read it on a post and nope

my big dumb head didn't figure it out on its own...

which L6Perry had sorted us right to begin with ... or even had it in the manual to begin with

I been working on this off and on for 2 months

Isn't that sort of what I said a few posts back? The treadplate is the recto model and it is a park 75 not a Marshall jtm 75. But that aside I am glad u got it sorted :)

Well I had better luck with the patches going one preamp + cab using

I: Fender Blackface Deluxe
II: Marshall Plexi JTM 75
III: Vox AC30
IV: Treadplate + voicing IV on amp

cheers

I assume you have a DT50 combo then, as it does default in the new FW 1.20 to the correct amp as the L6Link can see the DT50. but that's the output cab and mic compensation for being into a combo power amp, the amp/line is simply the output level and doesn't affect the tone. but with a tube power amp you need it to line, as all prewamps output at line level (or should).. L6 just gives you the flexibility 'just in case' you need amp level.

load of rubbish. i was wrong there. seems like it has no effect on the L6Link on the HD500 (I asked someone with an HD500 to check for me). I've not had time to check on my HD400 but I will, but I'm assuming it'll be the same.

ah I see where you're coming from with the channels/voicings thing... Chan A and B, 'CAN' be the same voicing if you want.. that's the added extra feature that most other amps wont give you. but it lets you choose which of the 4 voicings, topology and pentode/triode you want for channel A, and then totally seperate from that you have the same settigns available on channel B to do what you like. no presets and all the rotary knobs are not stored (they are at the setting hte same as the knob position... BUT if you change voicing, class and pent/triode those 3 settings will remember for chan A and sepsrately for chan B, until you manually change them, when you're on the specific channel... to me that's the best of all worlds, and also very simple for people who want a 'proper' tube amp and not a spider valve with its LCD screen, and lots of presets and FX... not knocking that though, just I know some people that just want a straight forward tube amp, and I think L6 have a good idea to then be able to expand on it when using the POD HD if you want..

Hey guys

On my hd500 the line/amp switch is states only for 1/4" are you saying that if connected through the L6 link that the line/amp will be effective or is this an internal setup that I am not aware of, when plugged into the dt50 the hd defaults to combo pweramp?

Also yes I have to agree as stated in my earlier posts (and posting of patches) that the preamps are the same (with tweeking) as the amp, however like said above without proper documentation and perhaps because I am not enough of a gear head I needed a push in the right direction. Thanks to all those pushing...

It would seem to this nongear head that L6 could do a much better (which seems weird to say considering I printed out a considerable amount of manuals) of demo/guide have someone dedicated to do nothing but demos of how to do stuff on the new and old gear. I know there is some but the ones for the podhd are very simple basic and limited.

On another note and I do not know if I showed my arse in here or other threads but somehow I got it in my head that the dt50 does not switch voicings and that channel A and B were of the same voicing always. When my amp spazzed out on me yesterday (voicing 3 lost its balls somehow and I had to reinstall firmware) I did find it (after reinstall) was remembering different voicings per channel A and B. So most of my complaints went out of the window with that seeminly obvious revelation. But I think its important to not only to acknowledge my findings but also my mistakes.

cheers

I've actually suggest to L6 that there's an FAQ document created for it. maybe it should go into the advanced manual too. you make some good points.

sorry for my misunderstanding. sometimes on forums it's hard to understand who's talking to who :-)

from my own personal point of view, the only confusing bit was the dual recto model in the HD vs the dual recto voicing in the DT50 not sharing by default the same NFL, but the rest was obvious to me when I thought about it. maybe I've just been using L6 gear for so long, as I guess have the people making these things at Line 6... so to say the models are the same, seems like how to set the rest up would seem obvious.... but I guess you're telling L6 (and me) that it's not. and your opinion as a user is just as valid as mine or line 6's.

Cheers

Hi Rowbi, thanks for your efforts. I am pretty shure that actual and new DT50/HDXXX-user will benefit from an offical LINE6 paper (FAQ or chapter in the link manual) how to run the original DT50 voicings via pre amp models an the POD/HD AND how to run the rig for LOW VOLUME level.

The possibilty to switch amp models ON and OFF via a FS-assign is not a working solution to me if I want to use a specific pre defined channel-B DT50-voicing. Because as a live oriented musician I can not see how to level huge volume differences (for example the Treadplate model on channel A if the amp model is ON and VOX AC-30 as the default B-channel if I switch the amp model OFF) with ONE mixer in the same patch. This is a knock out criteria to me. Any midi solution other than the L6 link when using the POD/HD with the DT50 seems to me the wrong road too. But again: I think all these different ways/discussions how to control the DT50 other then the L6 link while using a POD/HD are an outcome of a lack of really needed information to the user.

Regards.
