JTV89f modelling sounds very hot

Recommended Posts

Hi guys, im a long time variax user and this one has stumped me. I have a JTV89 from 2011, works perfectly (although the volume/tone/pickup selector unit will be needing replaced soon). anyway, i also have a JTV89f and the past 2 or 3 weeks the modelling sounds are really hot, like the gain is too high. Clean sounds sound horrible and the acoustic tones are utterly unusable. I have both guitars on firmware v1.9 (as i prefer that to the HD modelling). The 89 sounds fab on the same patch though my Helix but as soon as a swap over to the 89f it is just horrible. What could be the problem???

89 and 89F are slightly different.

Flash versions are slightly different.

One being a tremolo bridge, the other not, firmware is programmed for that aspect of it,

so there will be a difference in sound.

i dont think its a firmware issue. i always run v1.9 on both my 89 and 89f but this distorted sound comes from the mags as well as the modelling and has only appeared recently. Would it be a jack input hardware problem?

That definitely is weird. If you're comfortable doing this, it may behoove you to reseat all of the connectors you have easy access to. Just to do something that might correct the issue. This is the first time I've heard of this. Have you fired up Workbench just to see if somehow the Golbal level got tweaked without you're knowing it. I don't know how that would happen but I guess it would be worth a shot.

Don't know about the distorted output issue, but it would be worth a try to re-flash the firmware... sometimes that corrects various different kinds of Variax weirdness. 

 

As for the scratchy volume pot...eventually that happens to every guitar in the universe, and is easily remedied. A quick blast of contact cleaner should suffice.

Hi, ive tried to re-flash the firmware to no avail. I think there may be a deeper issue with the pot as its cutting the signal as well as been scratchy. i think the whole volume/tone/modelling assembly may be failing..

UPDATE : I knew it wasn't a firmware/software issue so the guitar was sent to a Line6 repair centre where the main PCB was replaced. Everything is back to normal... for now.
