So we've got a new singer and he wants us to tune down to Eb. Bassist was complaining that he'll have to relearn all the songs (he has a 5 string bass) since tuning down will cause him to re setup his bass, adjust the truss rod etc... Is it really that big a deal? I tuned my PRS CE24 guitar today and no issues at all, intonation is great, it's a bit slinkier but that's it. Slight buzzing now but doesn't come through the amp. Thanks!
