I’m going to talk about a common problem that I hear quite often when I’m out listening to bands. It’s a problem I’ve encountered working with various musicians in my studio as well. The problem that I’m talking about is the use of several different electronic tuners while tuning the various instruments in a band. You would think that a tuner is a tuner and that they’re all properly calibrated but the truth is that any individual tuner can be slightly out of calibration. If you have two different tuners and they’re both a little bit out of calibration, let’s say one is slightly sharp and the other is slightly flat, you’ll hear a big difference in tuning between the different instruments that have been tuned on them. The audience will simply hear an out of tune band which isn’t good for any performance by a live musician.
