gathrasher Posted July 8, 2013 Share Posted July 8, 2013 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 ?

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 ... Greg Quote Link to comment Share on other sites More sharing options...
snhirsch Posted July 8, 2013 Share Posted July 8, 2013 Anyway to fix this or do I need return the instrument? Thanks in advanced ... Greg 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.

gathrasher Posted July 8, 2013 Author Share Posted July 8, 2013 Yes, I've tried the factory reset. Same results. Similar tunings after reset. Can't redefine through virtual capo. Quote Link to comment Share on other sites More sharing options...
TheRealZap Posted July 8, 2013 Share Posted July 8, 2013 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.

Kcharriq Posted July 9, 2013 Share Posted July 9, 2013 You may also want to try a different amp and cable. I was having problems and when I raised the volume on my DT-25 or switched amps the problem went away. Quote Link to comment Share on other sites More sharing options...
gathrasher Posted July 9, 2013 Author Share Posted July 9, 2013 Reflash and cable exchange didn't work. Line6 support recommends repair @ service center. Thanks for your suggestions. Quote Link to comment Share on other sites More sharing options...
Kcharriq Posted July 13, 2013 Share Posted July 13, 2013 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.

gathrasher Posted July 31, 2013 Author Share Posted July 31, 2013 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.

snhirsch Posted August 1, 2013 Share Posted August 1, 2013 Very interesting! When you say reversed, do you mean the two strings were swapped with each other - or - that they were individually out of phase? Quote Link to comment Share on other sites More sharing options...
fr0sty Posted August 1, 2013 Share Posted August 1, 2013 I am interested in this also. If anyone has gut shots of how the piezos should be wired, I would appreciate seeing them. Quote Link to comment Share on other sites More sharing options...
gathrasher Posted August 4, 2013 Author Share Posted August 4, 2013 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.
