    Tuner issues - tuners disagree from each other

    Also, the strobe tuner in the Axe-Fx uses a different algorithm and is limited only by the accuracy of the crystal oscillator. So even if 0.6 cents is somehow not accurate enough you can use the strobe tuner.

    Tuner issues - tuners disagree from each other

    Several posts above yours I stated the tuner isn't designed to be an intonation tool. It's designed to tune a guitar at a gig and it works extremely well for that purpose.

    Tuner issues - tuners disagree from each other

    The tuner isn't designed to tune notes that high. It's designed to tune a guitar. Typically people tune open strings and the tuner is optimized for that. I'm not even sure what the point would be tuning a guitar on the 24th fret.

    Low harmonic content of a real amp

    That's called "intermodulation distortion". It's the difference between the two frequencies. If you play, say an A 440 and and an Ab 415.3 the difference frequency is 440 - 415.3 = 24.7 Hz. If you do a double-stop bend the difference frequency will go down as you bend the note up. It's not...

    That's actually sort of one approach. You put the signal into a comparator which generates a square wave. Filter the square wave and then use an envelope on the filtered square wave with the original input as the input to the envelope detector. I wouldn't be surprised if that's how a lot of...

    Why do some IR's and DynaCab's seem to compress more than others?
