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???
