Can't change alt tuning after firmware upgrade in James Tyler Variax Guitars / Workbench HD Posted September 11, 2021 I bought the 89f because it had a floyd on it but hated the tunings on it. I like the standard one on the strat and other guitars. I seen there was a firmwire update and did that. Now I can't change any tunings, and after the firmware upgrade two of my tuning were messed up. I am hoping there is a fix for this.
