Spider V Classic 15 Tuning Problem in Spider V Posted February 21, 2018 Well it sounds like you found the tuner. So, if I understand you right, your having a problem getting the strings to show centered on the tuner? meaning in tune? I use my tuner in my Spider IV as you described, but I dont have any issues, when you use your other tuner stand alone tuner, do you get the guitar in tune? I own a sabine chromatic tuner I use at home, and whether I use that or the line 6 I am able to tune each string to perfect tune. It sounds more like the guitar than the tuner to me, but I dont know what your guitar is, how it is set up, what gauge strings you use, what condition the guitar is in, whether your intonation is set up etc.. Start with this, can you tune your guitar with any tuner and get all 6 strings in tune?
