I have just bought a factory refurb JT variax with floyd rose. I like it alot and have started trying the different tunings. I have it run through a helix floor model and like lots of overdrive and distortion. The standard and drop d tunings are right on the money and sound great with all the different guitar models. But as soon as i switch to 1/2 step down, it sounds awful. I play with plenty of volume so i am not hearing the strings in the true e tuning ringing out as per instruction manual. Anyone else have issues? I like the guitar and don't want to send back but this is a deal breaker if it cant be fixed. I have done a firmware reset using the line 6 monkey.
