Last time I rehearsed with the band, my guitar was not in tune with the other guitar. I tuned with my Kemper and the other guy with his tuner device and then we still wasnt in tune so I followed his tuning. Thought it might have been something temporary... now... I just got a new Gibson SG with the Gforce and lo and behold, when the SG is autotuned in standard the Kemper says it tuned close to a halft step too high. Did I manage to change some setting in the Kempers tuner or what the heck is going on? Any suggestions?
