Hey Folks, I've been a 4 string player forever and need a backup axe in case I break a string. So, I went into Guitar Center to look for another 4 string. While I was in there I fell in love with an Ibanez 5 string. Do you think I should go for it..a 5 instead of another 4? I mean, how easy is it to play both 4 and 5 and always switching off? Thanks in advance.
