Is JTV sensitive to different string guages?
by Nipp on 2013-02-03 04:58:19

Hi

Reading about how Variax system seem to work with taking part signal from piezos and emulations, and some people also get different sympathetic resonance issues with different tunings - I wonder about this.

Saw the video from NAMM and 89F demonstration, he said it was delivered with 010-set, but he was about to put 011 set on it.

011's and 25.5" scale length, that's heavy duty.

Any notes from Line6 in manual on string guages or brands at all?

Thinking that different strings have different properties and produce harmonics that Variax is not tested with.

And locking nut and bridge saddles, can you do anything to these to fit other guages of strings?

The FR bridge saddles, how about them - any limitations?

And finally - are the nut and bridges shipped with 89F standard that can be bought elsewhere for replacement?

Thanks.

Best regards

I experimented with this a bit. What I discovered is that 9's didn't work as well due to the piezos. Essentially you can equalize magnetic pickup sensitivity by adjusting proximity, but since the piezo are not adjustable, string mass matters. I found that 10's or 11's had little variance from each other but were far superior to the 9's and made the accoustic models sound better. Another thing I found different is that slight string buzz that magnetic pickups ignore is present in piezos so I had to set the action to absolutly no buzz. I found that higher guage strings allowed for a lower action without buzz. Hope this helps.

It really helped - thank you.

I use Ernie Ball hybrid set 009-046 on Gibson guitars and find that really nice playability and sound.

I use the same on a Fender, but find these a little bit heavier since 25.5" scale length.

So I almost would like to go lower guage.

I play 011-052 hybrid on acoustic, but that is such a different playing style that it does not matter that much. Not so much bends and vibrato stuff.

I'm glad I asked - makes me re-evaluate going 59-model perhaps.

I came to think about the configuration tool.

Are there maybe settings to adjust amount of level, or even eq from piezos that you can compensate for a thinner string having less energy?

I mean, the different guitars 69, 59 and 89  must have different response from body. Some have bolted necks and 59 have set neck etc. And 69 and 89F have different bridges.

Piezos would have different frequency content for each of these guitars, and then think about different brands of strings on top of that.

One guess is that all this must be taken into account to make Variax system work flawless.

Just a thought - curious what anybody might have to say - LIne6 in particular?

I tried compensating with the workbench. Sustain did improve but the general noise floor was higher. I also found with anything less than 10 gauge the the truss rod was almost at a slack tension and the tuning became more temperature sensitive. I guess it makes sense to me, as it really is accoustic pickup system that has been co-opted as a reference singnal to filter to create a desired model, that it would function better with higher guage strings.

Sounds perfectly logical what you are saying, thank you.

I noticed a loss in tone going from 012 to 011 hybrid in acoustic as well.

Thinner string, less string tension obivously does that and string simply cannot move the top as much.

May I ask - did you have a 59 model or any of the others with 25.5 scale length?

That also makes a difference in string tension, and 59 model would be more vulnerable for loss of tone going down i guage.

Does Line6 say anything in the warranty terms about that you need to run a certain guage of strings?

I mean, you would be more likely to get problems with everything working with to light guage.

I have the 59.

No official statement I'm aware of other than that they come stock with 10 gauge. I'm assuming that 10 gauge is the referance used for the models.

Material does matter. I used pure nickel DR strings and they  did not have the same as they have on magnetic pickups. They made the low end muddy through the piezos. I ended up using regular slinky's. I was able to get a 2 32nd inch action at the 12th fret on the high side and 3 32nd on the bass side (factory spec from Gibson for a 1959 Les Paul) with no buzz.

I changed my 69 to a set of 9's from the stock 10's it came with.  Absolutely no difference in sound output what soever.

Excellent, thank you.

My little theory then is that 25.5" scale helps since string tension is higher.

Thanks again.

I would also expect that the 69 physical construction differences from the 59 to effect sustain more than the string gauge. Bolt on necks and floating bridges are typically less energy efficient. Heavy tone blocks help this a bit. I would say in my experiments the tonal differences between electric models is really subtle but the accoustic models sounded less punchy.

I use 11s on all my JTVs. All my JTVs are 25.5 inch scale or will be once all transplants are done. To me they sound better than the 10s but I just prefer 11s on any guitar, not variax specific. No negative effects that I can detect.
