I've tried this with the clip on one....just totally inaccurate until I do 1 string at a time.The one advantage I see with a polytune feature is using it live. It provides the ability to strum the strings and see which one(s) are out of tune between songs then knowing which, if any, need to be tuned instead of checking each one. Fine tuning in this scenario with a floating bridge won't knock the rest out of tune. If you're going from standard to drop tuning, that's another matter.
Sorry to hear, I have the clip on as well and have used it the way I described with good success. Seems to be the nature of gear though; some things work for some people, not so much for others.I've tried this with the clip on one....just totally inaccurate until I do 1 string at a time.
I figured the one I got was defective. Good as a regular tuner, but useless when I strum all strings at the same time. I get incorrect readings.
I must be the only one who uses them and has no issue with them. Then again I never do the strumming thing and use it like a regular tuner. I never use the tuner in the Axe, other then as a mute.
