Re: How to create a detuned 12 string acoustic

support@line6.com — Wed, 06 Jun 2012 19:58:00 GMT

Problem solved.

Input 1 on the POD was set to Variax mags and Input 2 was set to Variax. So even though I couldn't hear the strings acoustically I was still hearing them in my headphones from the magnetic pickups.

I just have to decide if I prefer the sound of two variax inputs panned hard left / right or a single variax with the second input on the POD set to something I dont use (like a mic) and panning everything dead centre.

Thanks guys.

Definately running with firmware 1.82. I have even reinstalled it in case there had been any installation problems. I am playing through decent sound isolating headphones so I am definately not hearing the guitar strings acoustically. This had been an issue when playing through studio monitors (even really loudly) but since using the headphones everything has been good.

Referring to my original answer to silverhead. I understand and agree with his answer to me.

it may just not be possible to have an alternate tuning on a 12-string model. I know that this was the case in pre-JTV Variaxes; the 12-string models were themselves an alternate tuning of a 6-string model and you couldn't apply two alternate tunings within the same model. I frankly don't know if the JTV technology now supports that - I haven't tried it,

Can MerlinFL or daferalo explain how they are managing to detune a 12 string model? Do you have a Variax model file you can share?

To close out my original post. I tried connecting an active studio monitor to the FX send of the HD500 and this worked. I have also tried connecting the monitor to the 1/4" unbalanced output on the HD500. This also works.

I am currently trying to decide which method I like the sound of best.

The JTV has the latest firmware 1.82 installed. When I thought about your answer it made sense that it probably won't be possible unless the 12 string model was capable of creating two alternate tunings of the original 6 guitar strings and only making the altered strings audible. Maybe in a future firmware update this will be possible.

How to create a detuned 12 string acoustic

support@line6.com — Sun, 03 Jun 2012 13:47:42 GMT

When I select one of the acoustic 12 string models on my JTV89 it sounds really good played through both studio monitors (from the 1/4" outputs on the HD500) and also through headphones.

I have the guitar tab for a song which says it should be played on a 12 string acoustic tuned down 1/2 a step.

With the 12 string acoustic model selected I turned the tuning knob on the JTV to 1/2 step down but it just sounds all wrong.

I know it is something to do with the 'virtual' strings being added by the JTV to create the 12 string model as I can quite happily detune any of the 6 string guitar models using the tuning knob on the guitar.

I tried using the workbench software but only managed to achieve the same result as using the tuning knob on the JTV.

Any ideas?

I just updated the firmware and I would say things are a little better. I actually found the biggest error I had made was panning everything in the mixer to the left (I only have one studio monitor as a stereo signal is not important to me). The next biggest error I had made was having the variax selected as both input source 1 and 2. I selected input source 2 as MIC as I knew this will never have anything plugged in to it and the sound cleared up even more straight away. This was most notable with the 12 string models and anything using an altered tuning. (less warble)

The cable supplied with the monitor was 1/4" mono jack to XLR which initially seemed ideal for connecting to the FX loop on the HD500 however this was just a workaround I had heard about on the forums. From what I have read the correct way of using the HD500 with the acoustic models of the JTV would be to use the balanced XLR or unbalanced outputs direct to a mixing desk, studio monitors or PA. To see if there was any improvement to the sound I plugged the studio monitor into the left 1/4" unbalanced output of the HD500 but there is no noise at all through the monitor.

What am I doing wrong?

Should there be an improvement in sound of the JTV acoustic models using the balanced / unbalanced outputs of the HD500 direct to a studio monitor compared to using the FX loop?

Thanks Sean.

I went ahead and bought an active studio monitor (Rokit RP5) just for use with the acoustic guitar models on my JTV. This came highly recommended as an affordable FRFR monitor. After some advice on other forums I connected this up to the FX send of the HD500 but starting with just a basic empty patch (amp block dead) and the FX loop after the mixer all the "dry" acoustic models are really boomy sounding. (My monitor volume roughly equates to that of an actual acoustic guitar) If I move the FX loop to before the mixer on the HD500 the signal going out to the monitor is too quiet meaning I need to turn the volume of the monitor up to maximum just to hear anything. Doing this really affects the overall sound badly. The solution I have found to the boominess is tweaking the preset with way too many EQ's and effects. The negative side is the character of the acoustic model is changed so drastically it could be almost any guitar.

I saw your latest video demonstrating layering with both mag and variax pickups sending the mag signal to a DT amp and the acoustic variax signal to Pro Tools. This inspired me to try the same thing with my "dream rig" but send the XLR output of the HD500 to the active monitor instead of a PC. As I don't have a second expression pedal to control the Plexi model volume I created the preset following your instructions but simply turned the amp in path "A" off to silence it. With all other settings exactly the same as your demo I could not replicate your results at all. The split path between the mags and the variax pickups was just not happening. I was getting just a small amount of sound out of the monitor regardless of whether I had the mags or the variax pickups selected on the JTV. If I turned on the Plexi model amp in the preset I would hear that coming out of the monitor and the DT25 at the same time.

It is a shame that I am such an incompetent fool with this aspect of the equipment as I am totally happy with the JTV/HD500/DT25 when used as a "traditional" electric guitar setup.

Would the RP5 studio monitor work from the FX loop? Does the HD500 care what it sends the signal to from its "FX Send"? Does the Studio monitor care what kind of signal it is getting?

Sorry if I sound like a complete bonehead.

Acoustic Amplification

support@line6.com — Sun, 29 Apr 2012 13:52:13 GMT

I have a Line 6 JTV-89 guitar which I normally play through a POD HD500 into a DT25 amp. 99% of the time this works just the way it should. By that I mean I am used to plugging a regular guitar into a regular amp, turning it on and making noise.

I have seen demos online of the acoustic modelled guitars in the JTV-89 and it sounds great. However when I try and create the same using using the JTV/HD500/DT25 it is nowhere even close. All the experts online say it is because acoustic guitars should not be plugged into guitar amps. Acoustics should be DI'd or amplified using a PA or something which is FRFR. I have no idea what any of that means. (I play guitar for fun at home)

I have been advised that I should create a preset on the HD500 with no amp model selected and use the FX loop in the preset to connect to some form of PA / powered speaker at "stomp box level". That way the DT25 is effectively bypassed.

Any suggestions as to what speaker type thing I should get? I am not looking for "Pro" gear. I am not interested in gigging with it. I just want something that can plug into my HD500 at home so I can hear the modelled acoustic's in the JTV-89 as natural as possible.

Acoustic models

support@line6.com — Fri, 27 Apr 2012 19:41:13 GMT

I have just watched the new youtube video with Sean Halley introducing the features of the JTV v1.8 firmware. The acoustic sounds are amazing. I have a JTV-89 / POD HD 500 / DT25 dream rig setup. I plug the guitar into the POD with a VDI cable. The POD connects to the DT25 with an L6 link cable. I turn on the amp and POD, select an acoustic model on the JTV, select an acoustic preset on the POD and start strumming expecting gorgeous tones. Sorry no gorgeous tones. In fact it sounds as if my amp is broken.

I have been through EVERY preset on the POD HD500 that even remotely suggest "acoustic" including all the presets in the BASS/ACO/VOC setlist and I am totally lost. Most have no amp selected and the noise that comes out of the DT25 is just muffled rubbish.

How can I get the acoustic sounds that Sean demonstrates with just the dream rig? I don't have a mixing desk. I don't have a PA. I don't play gigs. I am not an acoustic purist. I am just a normal person who like to play guitar at home just for the fun of it.
