Jtv89f Alternate Tuning Issues


Recommended Posts

I recently purchased a JTV89f and I'm experiencing issues with alternate tunings specifically drop tunings.

 

                           Factory Settings            My Settings

Standard            E A D G B E                   E A D G B E

DROP D             D A D G B E                  E G D G B E

½ DOWN            Eb Ab Db Gb Bb Eb      Eb Ab Db Gb Bb Eb           

DROP Db           Db Ab Eb Gb Bb Eb     Eb Gb Db Gb Bb Eb

1 DOWN             D G C F A D                   D G C F A D

DROP C             C G C F A D                   D F C F A D

Min3 DOWN       Db Gb B E Ab Db           Db Gb B E Ab Db

DROP B             Bb Gb B E Ab Db          ? E B E Ab Db

M3 DOWN          C F Bb Eb G C               C F Bb Eb G C

DROP Bb           Bb F Bb Eb G C            ? Eb Bb Eb G C

BARITONE         B E A D F# B                  B E A D F# B

 

Discrepancies are found on the 6th and 5th strings only.

 

I have reflashed the guitar, changed strings, reprogrammed patches via virtual capo.  Virtual capo settings are erratic in pitch and tone.  I have to reflash to stablize the drop tuning.

 

Anyway to fix this or do I need return the instrument?

 

 

Thanks in advanced ...

Have you tried a complete Alternate Tuning reset?  This operation is described near the end of the Variax "Pilots Manual".  I don't think a reflash does this.  Worth a try before you return it.

I'd return it while the option exists.... but i do think a full firmware reflash might help....

i'd flash to an earlier version say 1.7x and then to the latest... it helped clear up an issue i had when mine was new.

I found that turning the volume up on the amp solved the problem with drop tunings. At low volumes it sounds terrible. I don't think this is a problem with the guitar, but how they do the signal processing for alternate tunings.

I was having harmonic issues on all my strings, so I don't think it's a problem with the guitar as much as the software.

 

On another thread the advice from L6 was to turn the amp up.

 

If you send yours back I'm interested to know if they fix the problem.

Hope they solve this in the next SW release, but doubt they will.

Update ...  I took the JTV89f into Sweetwater for repair.  The tech found the wiring reversed on the 6th and 5th string bridge saddles. After the fix, the warbling on the 6th string using detuned acoustics is gone. The boominess of the sixth string using the martin acoustic is gone.  Overall I think the acoustics sound better than when I bought the instrument ...

 

Repaired under warranty.

 

I've been using line6 pods and variaxes for many years.  I enjoy the flexibility they provide.  However the last two items I've purchased through Sweetwater (PODHD500 and JTV89F) have had hardware issues.  Definitely try before you buy.

Clarifying ... The wire intended for the sixth string saddle was attached to the fifth string saddle instead. The fifth string wire was attached to the sixth string saddle. I didn't look inside the guitar. I've been gigging with it this week without issue.

Ouch.  That would certainly cause issues.
