    Boss GP-10 is a synthesizer, using COSM technology, meanings that has no TRUE HARDWARE EMULATION, but synthesizes all the sounds it produces from "existing" samples. so the user IS FORCED 2 CHOOSE FROM PREDEFINED SOUNDS N' HAS NO ABILITY 2 DEEP-EDIT-MANIPULATE THOSE SOUNDS (eg change pots, alter mag position+angle+wiring plus plus plus, etc, etc).  u cannot do these "magics" on the boss/rolland synths, can u?



    The GP-10 is a stripped down VG-99 - both have Roland Hexaphonic COSM processing - no sampling is employed on  1995 Roland VG-8, 2000 VG-88, 2007 VG-99, 2014 GP-10.

    COSM Revisited A Fresh Look at the Amazing Modeling Technology Inside BOSS and Roland Guitar Products

    By Jim Bybee




    Here is the GUI for the 2001 Roland VG-88 - which shows the Guitar Modeling and movable pickups - this inspired Line-6 to create the Variax. 






    To me the biggest difference is Variax A/D and DSP is located in the Guitar,  - Roland COSM VGuitar 13 pin systems place the A/D and DSP blocks in an external unit.   







    Suggest read the S.O.S Review of VG-99 for an overview of Roland Hexaphonic COSM processing







    Although guitar modelling is no longer a novelty, we should remember that Roland pioneered this important area of guitar processing some 12 years ago with their VG8 system, which modelled not only amplifiers, effects and speakers but also guitar pickups and pickup position.

  2. Rick,


    Thanks for the feedback ( we are neighbors - I'm in San Luis Obispo and play in a local surf band " The Dentures" 


    I'm on the fence  regarding M20d vs Touchmix 16. Going to buy one this week 



    As a long time Line 6 user ( and follower) -  Frankly I'll probably buy the TouchMix16 as it provides a better fit for my current gear and way I work. - for the following reasons:


    * 3 year warranty from a company that provides excellent global service support network. QSC sells Service Manuals and parts to end users ( I prefer to maintain my own gear when it falls out of warranty)   (Good Luck obtaining a M20D service manual - or parts) 

    * 20 channels of recording 32 bit Broadcast Wave Files at either 44.1kHz or 48kHz + 2 Track mix to attached USB 3.0 drive  ( goal is sell live show CDs  - I'll use a Samsung 840 EVO SSD) 

    * More XLR  I/O that works with the 6 powered PA cabs I already own - ( no need for L6 Link ) 

    * Independent 48V Phantom for all 16 XLR inputs 

    *  input Gain Trim controls in the analog domain -  these important gain set elements must occur " pre A/D to  yield optimal SNR and Dynamic range for each channel -  I can label these where they need to stay) 

    * I have 3 iPads myself that I can allocate as virtual control panels  =  each screen running different views of the array of controls I need instant access to during sound check. 

    * I feel the Touchmix16 will be more traditional to operate and far easier for me and my band to understand (less cartoons ) and support for 10 iPads to members to adjust monitor mix with less training.

    * Lower Latency ( under 1.6ms Input to Output) 

    * After the Yamaha  acquisition of Line 6  - I'm NOT expecting any further Line 6 firmware updates on M20D - (2 year old products are legacy in this world  

    * After weeks of research,  its annoying that a true Block Diagram Signal Flow chart is no where to be found for M20D

    (Touchmix 16 Block Diagram is here on page 63 :







    in my post i was talkin'abt guitars, not pedals...

    Last I checked the title of the thread was "Variax Vs. Axe Fx Pitch Shift?""  - a discussion of best Pitch shift - so just mentioning the available alternatives  available today  - for those who want to know. 



    Axe FX is not a guitar either.


     "pls correct if i'm wrong but i believe the only true hardware simulation guitar is the jtv, all others are based on sound sampling..."



    Again - not true,  find a Roland dealer and play a Boss GP-10 ( the latest Roland "VGuitar " system) and judge for yourself.

    Why was the Roland VG-99 so misunderstood by the public?

    Was it too open ended and not pre EQed enough for the average guitar player to understand?

    Was it just too deep for the average guitar player?

    Did Roland them self never realize the potential of the VG-99??


    I sit here staring at the VG-99 and wonder how in the world it is not at the top of the guitar players wish list.

    In all my many, many years in the business I have never seen anything so misunderstood.





    Have you done any side by side comparisons between the GK+GP acoustic models vs the JTV acoustics?


    Of course - but the results are not a popular topic on a Line-6 Forum ;)

    (See my earlier post on this same thread on page 1) - I'm not paid to post my opinions which in 2014 are not too popular around here .


    and I'm not an "Armchair theorist"  - I have receipts (and the hole in my bank account) for all gear I discuss. 




    It boils down to who has the fastest hexaphonic Guitar Modeling DSP  system in 2014  - and IMHO the Boss GP-10 is the current king

    When comparing real guitars, I've found most Strats to be brighter and thinner than Telecasters. The single coil bridge pickup on a Tele can actually sound pretty meaty, whereas with Strats, it can be a struggle to fatten that up


    +1 !!


    a Stock Tele is "meatier" sounding than a Strat - mostly due to more coil windings on Tele Bridge PU and and the solid metal plate mounted under the bottom of the Tele Bridge PU - (which is missing on stock Strat Bridge PU's) - both contribute the the Teles fatter tone when the Guitar Volume is on "10" 


    Remember the 1st Led Zep album was cut with Page playing a Tele on most tracks.



    Classic "Twangy Tele" sound - is owed more to the 1 meg ohm Vol pot with .001uF "Treble Bleed" capacitor  - which was stock and used on all post "1967 style Fender Teles. Play a 1968 Fender Tele on "7" and you have a very bright tone (that gets brighter) as the guitar volume gets turned down 


  8. IMHO - Mechanically coupled adjacent string piezo saddle crosstalk is the "limiting factor" for accurate DSP created Alt Tunings on All Variax's 


    The Graphtech Saddles have a wider surface area that reacts to any vibrations - (including adjacent strings)which means Variax Alt tunings will suffer odd sounding anomalies compared to a Variax with stock factory LR Baggs piezo saddles - 


    The ultimate expression of focused vibration piezo PU saddles technology is sold by RMC pickups in Berkley,CA  - this is what the high end Godins with 13 pin Synth Access employ    


    Is it as simple as taking it to a local guitar shop to fix? Can't be bothered with trying to deal with returning it the online shop I bought it from if at all possible?



    Most Guitar shops I know need to guarantee their work, as a result if they are not already a pre-approved Line 6 Service Center, most Guitar shops are very hesitant to work on the Variax.

  10. My 2 cents - DSP created Alt Tunings require effort and this adds latency.

    And as DocSmith43 noted above, the  Banjo or Reso models also yield a delayed output that depending on your experience and ears  - is either acceptable or not.


    It boils down to who has the fastest hexaphonic Guitar Modeling DSP  system in 2014  - and IMHO the Boss GP-10 is the current king






  11. Also check for G string binding in the  Nut slot ( see my Avatar - for pic of my JTV-59 with Bigsby that always stays in tune)


    After I slightly opened up the Nut slots (with Warmoth Nut Files)  I then use Big Bends Nut Sauce to lube the Nut.




    Upgraded the Tuners to GFS Locking Tuners $32 - these are actually from the same Asian supplier that Line 6 uses and bolt right on - 
    The "G" string is always the most problematic for me with most 3+3 "Gibson style headstock guitars
