Headstock tuner that isn't a clip on.

That looks a good idea. Shame no Les Paul ones yet

If they had one that worked on both they could sell a lot if marketed well

It looks like a really good idea.

I have a Peterson Stroboclip and for sure they are accurate- but you don't you find them difficult to use on stage?

I never tried Steinberger tuners, but that makes sense with the gear ratios. 

I find with my guitars I'm just messing around too much with the Peterson and the less accurate Snarks get me into rough tuning quickly. I'm usually tuning the guitar between songs while I am talking to the audience so I am only half paying attention when I am tuning

Yes. used to have one and it was a pain when gigging.  Took way too long.  Gave it to my son and just use the TC clip on which is plenty accurate for me.

For me playing mainly lead, it doesn't really matter too much about being perfectly in tune.  I can always bend stuff up

Now that's quite a unit!

When I started assembling guitars I began to want better electronic tuners for setting intonation. When I bought my Peterson StroboFlip, I was shocked at the differences it picked out that standard tuners just ignored. Occasionally, just out of laziness, I've used the built-in electronic tuner in my Strat. It'll certainly get close, but the guitar never sounds quite right. If I then hook up the Peterson tuner, it'll find things, particularly on the G and B strings that aren't apparent on the Strat tuner. And, in the end, the Strat sounds sweeter when it's tuned with the better tuner.

Yeah, the StroboFlip's a bit bigger. I thought it was particularly appropriate for me, building guitars, because it's well suited to use on a counter or bench, and the hinged lid will adjust to any angle, so it's easy to see when you're working on an instrument.

I really like the fact that it came with a bracket that made it easy to clip onto a mike stand at whatever height is comfortable. When I used it at home, just for playing, I'd clip it onto the pole lamp that sat next to my Twin Reverb

The StroboFlip has a lot of extra features that aren't absolutely essential but are nice to have. There are a selection of sweetened tuning that are tweaked to compensate for the untempered nature of a guitar and that lend themselves to particular styles of music and the tendency to play certain genres on different positions on the neck. There are other things too... the ability to tweak the tuning so if you're someone who likes the idea of A432 tuning rather than standard A440, it'll do that. Also a specific twelve-string tuning mode, a bass tuning mode, the Buzz Feiten tuning system and tunings for other instruments. They don't make that model anymore which is really a pity. Now, you need to get into the professional models that cost multi-thousand dollars to get some of those features.

Well that's why you probably wouldn't see it right on the stage.
They work great--if I found a decently priced one for sale I wouldn't hesitate to buy it.

The ones I've seen seem to sturdy.

But I wouldn't really put it to the test--just in case.

I do believe some of Peterson's products have been at least partially based on it.
And with good reason, if they were.

Last time I checked $300-700 Canadian-and normally s I see them only online--also shipping.
Depending on year. model, condition & seller's greed (at least int he higher ranges)
You do sometimes see them for less.
If I gigged or did guitar repairs or construction, etc, the lower end of that range would be worth it.
but for a home guitarist who sometimes plays with friends and at church-- when there isn't a pandemic--that just feels a bit steep.

Still if I ever find one in person I would consider $300 or so.

if I saw one closer to $200--then No-brainer territory 

So within the range I've seen.
Too pricey for me.

I am okay with the thought I'll probably never own one.
