    Using the VDI, u get only one A/D convertion, taking place at the JTV piezo section.


    I should point out I use the mag PU's 85% of the time  - since I still consider all DSP Guitar modelers to deliver lower performance for my playing technique  


    I like the GFS Rectotron Liverpools - as these deliver similar tone as my 6120 Gretsch with  TV Jones Filtertrons.


    - lots of Palm Muting here - so using a 1/4" connection avoids the Internal JTV Variax A/D>AES/EBU encoding > VDI> AES/EBU decoding.




    I believe there's another differentiating factor besides the A/D and D/A conversions. In the POD HD, as I understand it, the Input-Z parameter applies only to the Guitar (analog) input; it does not apply to the VDI input.



    By using the 1/4" Input on the HD500, in this manner i can actually use the HD500's programmable 1/4" input Impedance choices - for old school Tube Amp performance characteristics simply working my normal passive PU Vol/Tone pots when the JTV-59 in in Mag PU Output mode.  



    I could maybe agree about loudness, but frankly, I don't want to play with a drummer that cant control his dynamics.


    Agreed - and in most of my bands i play in today playing too loud will get you fired.


    But there are times when the band must breath fire, and its important to have the right tools for the gig. 

    If you play in a 70's Tribute Rock Band at festivals, look elsewhere.

  3. I think its best that all party's actually go to a Guitar Center and demo the Amplifi 75 and 150.


    I have demoed the Amplifi 150 at 2014 Winter NAMM and for verification last weekend at Guitar Center Hollywood.


    Its fine for its intended function - a nice home practice amp -


    But due to Amplifi's moderate SPL level it does not move enough air for live Rock Band use , its going to get drowned out by a drummer.


    Also no D/I Out kills all enthusiasm for live use. Id rather bring a '65 Deluxe Reverb and some FX pedals - as that would have more SPL for live use compared to Amplifi. 


    I also own a Line6 Vetta Combo and a Line6 DT50  - both these work well live and leave the Amplifi where it belongs, at home in the living room.

    All the discussion I've read about the Workbench level settings suggests that the gain adjustment occurs between the piezo pickups and the AD converter.  While that certainly would be a logical place to put it, does anyone know for sure if that's actually the case?  I'd certainly hope so, but it would be nice to hear confirmation from the Line 6 technical folks.  Hard to believe this would be considered proprietary information.



    Above is a JTV-69

    Actually each Piezo saddle signal feeds a fixed gain op amp that feeds an AKM5386 Stereo A/D There are three U2,U3,U5 - to cover all 6 strings.


    There is no "adjustable Gain" block in the AKM5386


    The Variax String Gain is accomplished post A/D inside the Freescale DSPB56725F DSP


    (trivia : The Mag PUs use a separate AK4556 Stereo CODEC (U6) - (for A/D for the VDI interface) and D/A for the 1/4" out  


  5. I played a Amplifi 150 at NAMM at the Line6 booth. It may be Ok as a home practice amp, but neither version (Amplifi 75 or Amplifi 150) is loud with enough SPL to keep up with a Rock drummer. So buy from a retailer with a return policy, and IMHO look elsewhere if you need an Amp to play gigs with . Just for reference, my 2005 Vox Pathfinder 15R (15 transistor watts) is louder than either of these Line6 Amplifi amps   

  6. I'm staying with FW1.9 - because these translate closer to the original Variax Models I know. HD 2.0 models all sound flat and lifeless to me




    There are still too many "gotcha's and hurdles" if you own a HD500X (cant use old Workbench) and if you have HD2.0 on your JTV ( must use the plastic Workbench USB to VDI adapter box to

    edit using "Workbench HD" app)  So I have to carry the equivalent of an HO Trainset  worth of gear and cables to Edit a JTV with HD 2.0 if Im the road 



    Meanwhile with only an HD500 and my laptop, I can still Edit Everything on my Tyler Variax with FW1.9 using the original Line6 Workbench app to Edit my JTV-59.(no plastic VDI box required) 


    Also I use the Mag pickups on my JTV-59  85% of the time. 


    I upgraded most of my JTV-59   - i own over 40 guitars and my JTV-59 with bisgby is my #1

     all details here:






    It has replaced my former #1 (seen below)





  7. i hope for all of us they hold true to this statement


    "Under the terms of the agreement, Yamaha will operate Line 6 as a wholly owned subsidiary to fully realize the compelling opportunities for the two brands with Line 6’s operations continuing as before and its management team remaining in place."



    I have the utmost respect for Line6 employees and Line6 Customer service - and hope this means an influx of operating capital

  8.  I own both a JTV-59 ( for the Les Paul Neck feel / ergonomoics) 


    AND a 


    JTV-69  - for my Strat  / Jeff Beck excursions.


    And despite the hype - I use the Mag Pickups 80% of the time on both.


     In 2013 despite all the breakthroughs I remain in the camp that still considers playing through a DSP guitar  / pickup modeler remains in the same realm as thinking an iPAd pinball game 100% replaces a real 1961 arcade pinball game  if you close your eyes and imagine really hard, you "almost" get in the same ballpark as the sound  ./ tone of playing the guitar being modeled, but with DSP modeling (Roland, Line6, Antares) there always remains a 2 dimensional quality on these systems, that an experienced player who knows and uses the tools provided with "real deal" vintage electric guitars will be able to pick out (or put down ) the Variax in seconds. 


    But I remain an advocate of DSP modeling, as it solves many logistic hurdles for the gigging musician who can only bring one guitar to the gig.
