I found this vid whilst browsing the net. I found it interesting - maybe you will (or not ha ha)?

I was playing my 2019 t386 last-night and decided to go a little lower with the action . It has some high frets to 12th and needs the drop-off from 12 up addressed . I have a 146 and a 59 that both needed the frets lightly dressed . These 3 guitar's were purchased new . My two acoustic Eastman's are fine . My er3 was purchased used and needed alot of work , electrical, finish , I think I just polished the frets but can't remember .
I don't mind doing the work and enjoy the quirks of trully handmade guitars. But it seems Eastman is missing a important part of the final set up , at least on my 3 new one's . I did see someone comment the same on another site . Wondering if anyone here has experience this?

This wonderful AC-630 recently came home with me. It sounds as great as it looks. Volume, projection, bottom end without getting muddy, yet clean across the register.
This is not the first Eastman I have had the pleasure of ownership, but it is the first super jumbo. Fit and finish are at their high standards, and did I mention tone?
Since I take weekly lesson from John (Chapbogie), I got to play this AC-630 when it first arrived. Like a sirens call, it would becon me to "come play, come play" every time I was in The Acoustic Shoppe. I hoped that one of you would save me and purchase this beauty. Thankfully that was not to be.
Last week on an unusual day off, I stopped in to really put the guitar through the paces (as I know them). John and I chatted for a bit about the guitar, it's build, etc. Then he said "play it and let me know what you think". Man, I ran through everything my cranium could think of; Stones, Robert Earl Keen, Little Feat, Robert Johnson, Guy Clarke, John Prine, The Beatles, on and on. This guitar delivered!
So John and I chatted some more about the tone, the quality, the beauty of this guitar, just comparing our impressions.
And now she rests comfortably in my arms.
If you get a chance to play an AC-630, DO IT.
I can also tell you that John and the folks at The Acoustic Shoppe are every bit as nice, warm, and honest as they are on the forums. Wonderful folks to work with.
Gotta run. Less keyboard and more fretboard time.

Had a buzz on the G string Ping tuner on my E10SS/V last week.
Pulled it out & re-seated, buzz gone.
Playing today the buzz is back.
Just ordered a set of Schaller Grandtunes. 
Saw a guy that did a drop in replacement with the Grandtunes on his E10SS on the Eastman owners Facebook page. They look pretty solid.
Guess Eastman had to shave a nickel off the tuners with the cost of the French Polish.
My other two Eastman's have Gotohs that are silky smooth.

Interesting video, https://www.youtube.com/watch?v=qOeb82oXF_Y 

The main differences although there are a few others Adi top, short scale for the Eastman vs. Sitka top and long scale for the Martin, And of course the price difference! 
You be the judge on difference of tone, to my ears the Martin barely sounds better, but it should for the price difference and a few other options.

I just joined last-night . Already have a question , my new t386 is beautiful . Acoustically it sounds fine , plugged in it's kinda lifeless. I played with the amp , tried my other amp . Not saying it's bad but not loving it . I'm thinking of changing to Seymour Duncan 59 bridge and phat cat neck . I already have the 59 here , what do you think ? Appreciate any input

I guess I should say I'm relatively new to eastman but have 5 already. Pretty new to learning guitar about 4years. I've been working on guitars for years to help rehab from a injury , finally sat down to learn to play . Have owned many guitars brands as a admirer, Gibsons, Godins , carvins and many more lol. Found a Eastman El Ray 3 that needed work , that did it . Love watching online how there built . The old-world construction hooked me . I started selling guitars to buy Eastman's .

Darn, I hate when that happens!

I bought a new E20-OM about a month ago from a local retailer. I just got around to changing strings the other day. When I removed all the strings, the nut fell off! I cleaned up the original & non-functional glue, applied a dab of tite-bond and am back playing. The good thing is that it was quite easy to polish the nut slots.

I like to take all the strings off at once when doing a string change, it's just the way I like to do things...plus, with a new acoustic I like to peek inside the body with a flashlight & mirror to see how it's built and if there are any spiders and such living in there

Never heard of Delbert McCLinton before Bert mentioned him. I checked him out and found this - which I REALLY like. Good honest, unpretentious rock and roll! https://www.bing.com/videos/search?q=+De...&FORM=VIRE

I am confused about which Eastman guitars have a center block and are fully vs. semi hollow. From the Eastman website: "Every one of our laminated thinlines has a center block that runs the length of the body right down the center." Both the T64/v and the T486 are listed under "Thinline > Laminate" on the Eastman website. They should both have center blocks. But every review of these guitars the internet contains describes the T64/v as fully hollow. Guitarist writes that "the T64/v is built without a center block" (https://www.premierguitar.com/articles/2...64v-review). And every review of the T486 describes it as a semi-hollow with a center block. Clearly, either the Eastman website is incorrect, or many internet reviews are incorrect (Premier Guitar ain't the only one to say something like this).

I hypothesize that part of what is going on is that Eastman laminated thinlines fall somewhere between traditional fully hollow and a fully divided two completely separate chambered semi-hollow. And the terms "semi-hollow" and "center block" aren't clearly defined and different companies use them differently. But that does not fully explain things. What I really want to know is what the differences are, center-block / fully vs. semi hollow wise, between the various models in the Eastman laminated thinlines. Particularly the T64/v vs. the T486. Does the T64/v have a center block? A smaller/thinner center block than the T486?

More information: I love semi-hollows, but I'm more of a heavy blues rock guy than a jazz player. I need to be able play with a fuzz pedal at stage volume without feedback problems. I played a T64/v in the shop the other day. Loved it. I love P90s, I like bigsbys. The other option would be the T486B. But that does not come in the violin varnish (which I love!), and I like the Lollar P90s in the T64/v more than the humbucker-sized Phat Cats in the T486.

Any information on the center block situation in any of these guitars, or experiences with gain at stage volume with them, would be greatly appreciated. I play in lousy bars and in basement practice spaces with a loud drummer, and while I *prefer* lower stage volume and realize that it is better for your ears and your tone, the reality is that things usually get loud, and I need earplugs.
