I'm considering purchasing a JTV 89. My hangup is that I don't know if I can do open tunings on this guitar, which is a deal breaker/deal maker for me. I know there are other models which will do this by default, but I don't like the look or the strat and LP style necks associated with these models. I also know that the 89 won't do open tunings as an out of the box feature like other L6 models. So to elaborate, I would like to know if I can program the guitar for the open tunings I want. I play a lot of drop tuning, shredder type stuff as well as open tuning, fingerstyle acoustic stuff. So the guitar must be able to do both with equal facility. Searched this on the forums, but no luck finding an answer. Any help is greatly appreciated. Thank you!
