Unfortunately, analogue equalisers introduce phase shift, a frequency-specific delay, and this can make matters worse. It also means, for me at least, that the new Fractal foot-controller, whose main distinguishing feature from other available foot-controllers is its access to the tuner data, is no longer on my 'to-buy' list.Ever since monitor speakers were first placed in a room for audio-production purposes, people have employed equalisers to compensate for what they perceived as impediments to a clear sonic picture. So, the bottom line is that the Axe's tuner is *useless* and nobody who cares about accurate tuning should ever use it. If you don't use the offsets but use the calibration method that I detailed at the start of this thread then you can only get a few strings accurately in tune. So, if you decide to correct the tuner's problems by using the offsets you can never use it to do your intonation and you have to always remember to tune to the open string, never a harmonic or a fretted note. If you play the E at the 1st string 12th fret, an octave higher, that offset will not be operative. The Axe tuner's offset for 'E1' only affect this exact pitch. Your open high E string is tuned to E329.628hz. The offsets only affect the exact pitch of the open strings. This is because of the nature of the Axe tuner's offset feature. Now, if you have the Axe's tuner set to use the offsets then you're limited to tuning only the open string, never a 12th fret harmonic or any other harmonic or any fretted note on that string. Everybody's Axe is likely to be different in this regard. Those are some pretty wild offset numbers! But they work. If I set the Axe tuner's calibration to A440 and adjust the individual offsets so that when tuning my open strings the Axe tuner matches my other tuners, I have to use the following offsets: I did that for all 6 strings and now my Ultra's tuner is accurate!Ī little bit of tinkering with the offsets and I realize now that it's even worse than I thought or imagined it could be. Example) from step 2 my Low E needs a 12.2 cent increase. Go to the Offset adjustment portion of the Ultra's tuner and enter the value for each string. So I entered 443.1 into Frequency 2 in the calculator. For Frequency 2, I entered each of my six string Values from step 1 above.Įxample) For low E string to be in tune on the Ultra I had to set the Calibration feature to 443.1. For Frequency 1, I entered 440hz since A = 440hz on my Ultra. I went to the second calculator down called 'Cent value of an interval'. Next go to a website with a frequency->cents conversion calculator like here: Using the Calibration feature adjust for each individual open string note and write those values down (see my post 3 posts up from this one).Ģ. Just wanted to advise that I tried this and it works. All you really have to do is play a test tone that represents each string's note, then adjust each string's Offset in the Ultra until it shows in tune. I still have a hard time believing that this can not be fixed.Įdit: I probably made this too complicated. In general, I don't trust the Axe's tuner for anything important and still have the Korg in my rack. I suppose it's possible that the Axe's tuner is even more accurate than the others, but I doubt that. It's the Axe's tuner that is the odd man out. Still, my other tuners all agree with one another. I've only checked it recently with one guitar and that guitar is ready for some new strings. That particular problem might be intermittent though. The discrepancy is small and it's probably not audible to the human ear. The Axe (calibrated to A441) will agree with the Korg and my other tuners (calibrated to A440) on my high E string, but the low A string will show up flat on the Axe when it shows as being in-tune on the Korg and my other tuners. It does seem accurate enough once its calibrated, most of the time.īut from time to time I'll notice a discrepancy on the lower strings (compared to my Korg rack tuner and my other tuners) while the upper strings are more synced up.Įg. Calibration to A440 will still vary from unit to unit.

He's made mention that the tuner's accuracy has been improved over a few firmware updates ago, but that's just its accuracy within itself. So my understanding is that this is not something that can be fixed via firmware. I'm still at 441 to match my other tuners.Ĭliff said that that the Axe's tuning calibration, as far as calibrating it to A440 is concerned, will vary from unit to unit.
