20 minutes for my steel string ovation Acoustic guitar and 20 minutes on my ovation classical nylon string guitar

For example, it went wild on an acoustic guitar and broke a string by over-tightening so quickly I couldn't stop it in time.

Honestly ive had it for 15 min and broke a string i was following the instructions just like it

If Roadie hiccups occasionally on a harmonic and doesn't get a string right on, I just tune the string again briefly, and it always cleans it up.

When I first got it, the auto-detect feature was extremely faulty, picking up the wrong strings over and over and nearly breaking my strings due to this, however they have patched the app, and the last 2 times I used that feature, it worked very well

I thought I'd try the auto-recognize feature to speed up the process, but the tuner would continually pick the wrong string and completely detune say, the "D" string thinking it was the "A" string.

Holding the device to your pegs while plucking your string is a little awkward, but unlike a regular tuner you just hold and pluck the roadie does the rest

I am one of those that sometimes just can't seem to tune properly and break strings.

Each time i attempt to tune it will come close to getting it, and then loosen the string to unplayability and the app stops and tells me to make sure i'm plucking the right string

I find the Roadie has cost me more money by breaking the low e strings

I did not have a full charge when I tried to tune the 4th "D" string on my Martin custom D, and I think it was having trouble communicating with my cell phone, so it wound the string so tight it broke the string.

The more strings you have, the more you'll love it.

Actually it worked quite well on acoustic guitars, never broke a string

n’t think I would waste my money to try it out
