This is just a simple post in case anyone still needs to use an amp for their acoustic amp patches.

I strongly suggest using the PhD Motorway amp in full mode with the default 212 speaker cab.  If you do choose this option within one of the Line 6 pre-made Acoustic patches with several EQs being used.  Please delete the first two EQs in the signal chain and then put the PhD amp & cab in front of all other EQs.  SOme of the FX may be better moved in front of the amp, but all EQs will work best after the amp & cab.  You might even find you could delete more than two depending on your personal taste or need for those blocks for other FX that will work under the DSP limit. 

Here a copy of a post from a question I believe is relevant to this discussion regarding acoustic guitar models and how (in my opinion and personal trials) to get the most from the new 1.80 JTV update as well as using it with any of the POD HD products..............

I understand you point of view perfectly as an Ovation acoustic guitar user.  But since I started in with the original Variax guitars with the electric model 700 I never brought my Ovations to another gig as I could get any acoustic sound I wanted with those guitars, and now the much improved JTV acoustic models.  Before update 1.80., I never had much problem dialing in a gorgeous tone with nothing more than one EQ used as a High pass filter and another for tweaking the mids thru highs of the guitar models.  I've read hundreds of posts talking about what players don't like about the various Variax modeled guitars.  I guess I've been a very lucky (or more experienced working with tone and all the controls Line 6 has always offered starting with my Vetta combo) person that I've not had most of the problems that I could not control or adjust as others seem to have had.

 

I also agree with the previous post that the sound many are reporting as "ambience" is not ambience, but what this previous poster wrote...the acoustic "box" or body of the guitar modeled.  I can only presume that line 6 was trying their best to capture the full tonal spectrum that an acoustic guitar made as the ones Line 6 chose to model are made and how they reproduce the string vibrations internally as well as what the combination of initial string sound, plus the subsequent harmonics and overtones, plus the size of the wooden body equal out to be.  It might sound like playing an acoustic guitar recorded in a bathroom, but I'm not certain that is what was done or intended.  So enough of the audio physics lesson.

 

I play in a rock band, and I've been using Line 6 guitars and their acoustic models since I got my original Line 6 guitar back in 2006.  I've never had any problem cutting through the rest of the band with keys and/or other electric guitars and acoustic drums playing from day one.  I've not made "crazy" EQ settings to compensate or played at twice the volume, I've just gotten excellent acoustic sounds and let them "speak" for themselves in the band environment.  I wish I could go to each Line 6 owners home and set up guitar patches that will work perfectly in their specific live performances, but this is not possible.  I will suggest the following...

 

1. If you have a POD HD unit, try using a FULL amp model and use the CABINET controls AFTER EQing to your taste.
2. I highly recommend using the PhD Motorway amp with it's default 212 cabinet.
3. Then using the Cabinet controls dial the RESONANCE up to 100, the THUMP to 100 and the decay down to about 30 to start.
4. If this seems to get the response, or much closer to the response you are looking for, then go back and tweak the EQ settings to adjust back to your tonal preferences.
5. I would suggest as just a guideline the following basic EQ settings.  Using the Parametric EQ on the POD HD unit, dial the frequencies or "Q" to the following four frequencies before boosting or cutting.  85hz, 150hz, 1.5Khz, 3Khz.
6. Then boost 3db or 4db + for 85hz, cut 3db or 4db 150hz, boost 5db or 6db 1.5Khz, and boost 2db or 3db 3Khz.
7. This "should" bring you in to a good range before final tweaking completely to your taste by putting a fair amount of attack to your acoustic models, dialing out the extra lower harmonics produced by both the guitar model and the cranked up cabinet settings, and the last to give you model enough brightness that you can adjust as needed while performing using the tone knob as the mic position control it is designed to be.

 

I've never previously written out any of my basic formulas, but I think it time to share some of my findings with the Line 6 community.  Hopefully my settings will help in two main ways...1) to let you hear what you can get from the gear you have and the updates Line 6 has made to produce the tone at reasonable volume levels to be very usable.  2) To get people pointed to the right directions with this new gear and the new capabilities.  And if JTV owners do not have any POD HD gear, all this can be done with an EQ of good sonic quality and proper EQ settings on an amp or mixing console.

 

All the best,

Neal

 

PS - if you have any results to share after trying my suggestions good or bad, please post them.  I can't get better at helping others if I don't know what I suggest is being tried and what the results for others turn out to be.
