Hello, I'm looking to get a seven string that can keep my guitar sounding tight and djenty ( we are not a djent band but love the tightness ) in tunings Drop G-F ( and possibly drop E, not sure yet ) I've been looking for something we can use that would fit our sound perfectly in the studio, as we use a lot of feedback and harmonics but also want to keep our chugs low and skull crushing. I'll just also use it live until I can afford to maybe get another guitar if it's not so astounding live. I've been looking for a long time, and as my band is now prepping to record our debut EP, we're getting some more professional equipment before heading to the studio. I've been extremely interested in the Ibanez Iron Label RGIR27, but I'm wondering two things. 1. Is this even a good choice? I'd like to go with the best choice within a similar price range. 2. Which of these would be better for the tunings??? This one Ibanez RGIR27 Iron Label Electric Guitar, 7-String, Walnut Flat Or this one? Ibanez Iron Label RG Series RGIR27BFE Fixed Bridge 7-String Electric Guitar Flat Walnut | Musician's Friend Also what's with the weird nut on the first one? Like what's it's purpose?
