Hello, sorry for my English, I am French. I want to buy a 7 strings guitar and need advice for these 2 models. ESP Ltd ec407 ec Ibanez rgixl7 I play mostly at home on a vetta 2 line 6. I want a 7 strings for more low power chords, and also more versatility. But I also shredd a lot. So which one to chose? I use to play on 6 strings Jackson with Seymour duncan JB and jazz. Thanks.
