Very accurate tuner. Charges on computer USB didn't think I would like that but I haven't had to buy a battery yet and the thing stays charged for ever. Very good for setting intonation. May seem pricy for a tuner but it's well worth it. I highly recommend this product. Thanks to Ben Robinson for all you do. Love Sweetwater

Sweet tuning in toxic environment?

Pedal steel players who are trying to sweet tune your instrument in a noisy environment - this is the answer. Just dial in the setting for E9 tuning and jack your instrument into the tuner and you've got it. Also, if you play other instruments with altered tunings, just dial in the appropriate setting for whatever you're playing. It's a very nice tool.
Music background: Mystified by many stringed instruments for decades


This gadget is a necessary expense for the pedal steel guitarist as well as the non-pedal steel player. It has all the "sweeteners" for existing pedal steel tunings in addition to a few non-pedal ones. Emmons and Newman are no longer with us, but they have left us a legacy with the sweeteners in the Strobe Tuner.

Money Well Spent

OK. Its just an accurate tuner, right? I've been using tuners for decades, right? Well, then why do all my instruments sound better now? I'm not even kidding. Besides its inherent accuracy, credit has to be given to how easy it is to tell with this thing that you are actually in tune ( no bouncing needle), and how much 1-3 cents on each string matter. I should have purchased this a million years ago, but I just didn't know how much it mattered. Oh, and I can also do my own intonations now, so that saves me money. This has already paid itself off in cost savings on set-ups. I did not expect that.

Your guitar is out of tune...

Firstly, it is fun to watch two sorry saps debate about the quality of different tone woods when their guitars are both out of tune. A cheap guitar that is perfectly in tune sounds better than an expensive guitar that is not in tune. This is a simple fact. Secondly, there is no such thing as "kind of" in tune. Your guitar is either in tune or is out of tune. Thirdly, your tuner might be accurate to 1/10th of 1 cent, but it has no way to convey this information to you. An oscillating arm that bounces around aimlessly or dual colored LCD can't communicate this degree of accuracy to you. Thus, even though your tuner knows how out of tune you are, it doesn't do a bit of good if it can't tell you how far out you are. That is where the strobe comes in handy. Stop kidding yourself, and get in tune. If you aren't using a strobe tuner then your guitar is out of tune. Plain and simple.
