I love the 6-string acoustic models, but the 12-string model sound a little worse than the previous ones to my ears.  I'm just figuring out my new JTV-59, so maybe I don't have something set right. 

Also, the amp models in the new HD500 2.0 firmware seem to have the high fizz again. Hopefully, I just need to tweak it somehow.  Curious to hear what everyone else thinks.

Im not pleased with the new 6 strings. Heres why. They have a much 'Roomier/distant' sound than the 'old' models. Its an early reflection sound that you get when pulling the microphone away from the soundhole of an acoustic guitar by a few feet. Its nice sounding, but I really dont want that built into the model itself. You can easily get that sound using an early reflection delay set to very low values. Having it built into the Model itself means you will ALWAYS have that distant sound built in.

Line 6 please make the 'old' acoustic models available, ie give us the option of storing both in the guitar.

There are times (ie playing live) where you dont want a roomy type acoustic sound and it needs to be tight.

I would suggest you play with the sound a little more.  These models are far less boomy but you can bring in more body by rolling off the tone knob.  I find it's a far more controlled sound all around.  To me the previous models had too much of a piezo boom sound to them and rolling off the tone knob made it worse.  Now you have a lot of useable tone knob control.  I used lots of EQ on my HD500 for my acoustic patches and you couldn't use the same patch for all the models.  Now the models sound better with nothing than they do with tons of EQ, IMO that's a huge improvement and you can probably make a patch that sounds good with all the acoustic models because you don't have to EQ the boomy sound out of them which was far worse on the J200 than it was on the D28 with the previous models.  Now they have body not boom. 

Here's a test for all to guess.

Attached are two recordings I made with Reaper using an HD500 as the audio interface. Both tracks use the latest HD500 firmware v2.02. Both were recorded using the preset 5B Piezo Acoustic in the Bass/Aco/Vocal factory setlist (I turned the Delay off).

One recording uses my 1972 Martin D-28 acoustic guitar (Indian rosewood), with after market Fishman under-saddle pickups installed in 1993. It is connected to the HD500 using the Guitar input.

The other track uses my JTV59 with the latest v1.8 firmware. It is connected to the HD500 via VDI. The selected Input is Variax. I am using the comparable Martin D-28 6 string (Acoustic Model 1, Brazilian rosewood).

Which is which? Which do you prefer?

I can hear both, but the volume is a bit low.

I say Track4 is your real guitar.

Track 3 sounds like the Variax models to me.

Track 4 sounds like the model, but I like it better.  As the promo material points out, the models incorporate miking the guitar in addition to the piezo, which is all you're getting from your real D-28.  Plus I think I heard a little digital sizzle artifact at one point, which gives away the model. 

Thanks for posting these.

There is no possible way that Track 4 is not the real guitar.

If Track 4 is the JTV, I will eat my hat and place an order immediately. But I know that it isn't.
