I'm a new owner of Variax JTV-89F
(by the way, I also had the 6th string loud resonance sound problem right from the start, just saying...)
Sadly, tuning down the string physically, which I always do make the string tension just the way I like, is made impossible to use with modeling. I've been experiementin and seems like tuning the guitar to Eb standard works fine with all the modeling. At D standard some glitching occurs. C# standard is where the problem really starts and unfortunately that's the exact physical tuning I want.
For some reason, at C# standard the 4th string gives that ring modulated sound with a wrong pitch. Other strings start glitching also if you tune down even lower. Also, the thickness of the strings doesn't make a difference here.
It has to be something with the programming right? Cause again, string thickness doesn't change the problem at all.
Modeling still works great with this tuning IF you don't use the alternate tuning knob or 12 strings where the Variax needs to detect the pitch.
But that kinda takes away the whole point of the guitar.
Before you ask "why don't you use thinner strings and tune to Eb then?",
I think a .010 string is way too stiff even at Eb because I like bending notes a lot, It's perfect for me at C# and I don't want to use .009's or .008's because even .010's snap sometimes.
Anything I could do to make C# work?
