Fret Buzz Question

Recently got used 2019 L3 HSS that I brought to my normal tech for a solid setup, string change and to make the bridge dive only. I had him lower the action very low how I like it. After my first gig with the newly setup guitar, I started getting some fret buzz on the high E and B strings around the 19th fret. First thing I did was change strings because maybe they had some dents on them. That helped a bit, but after a gig this weekend, the buzz has gotten a bit worse at the 19th fret. I’ve also noticed the strings for bending feel a bit tight or “chokey“ if that makes sense; to clarify, I can still do nice, wide vibrato, but it feels the strings or neck fight me a bit on it. I use 9 gauges and I like them to feel easily bendable because I vibrato a lot. I’m thinking he might have leveled a fret incorrectly or maybe put too much tension on the neck and it needs a hair of relief? Does this seem fixable with a little truss rod turn? I’d rather not bring it back and get charged again. I would also like to learn how to get better at all this setup stuff!

String action (measured by eye with Stew Mac string action ruler) =
High E is about .050 (close to .060),
Low E is .070
A string = .070
D string =.070,
G string = .060,
B string = .050

Neck Relief = I dont have a neck feeler gauge tool, but a .50mm Dunlop tortex pick moved the string when I tried to put it over the fret. So it is lower than that I guess
 
For lowest action possible, I set my EBMM's relief by fretting the 1st fret and holding the string against the last fret, then I want just the slightest "tink tink tink" when I press the e strings against a middle fret.

If that's there, the action gets set to where string buzz just begins. I too had a high e "damping out" ever so slightly, so the saddle gets raised. Really nothing else to do. But only a tiny bit at a time, until the string rings clear. Then I have to adjust any other strings to keep them at the same radius as the neck, which I do by sight, by slowly rotating the neck as I sight across the strings. Each pair should come into plane, while the others are just a bit lower.

This is assuming your frets are all correct, of course. But I'd assume you can use this same method with your Luke.

So making a truss rod adjustment won’t solve this?

19th fret? It may, but my understanding of setting up these type guitars, the relief is set to be very slight, then it's pretty much down to saddle height. Up that high on the neck, the truss rod isn't going to have hardly any effect.

.5mm is really low. I think that's the problem.
 
From EBMM site: (Go to their FAQ page if you want to see the steps for Vintage Tremolo, since your's is blocked, that might be more pertinent to your guitar.) Note the action heights they recommend are 2 to 3x's higher than yours. I think your action is simply too low.


Luke Tremolo Setup

NOTES:
The Luke tremolo is set floating at an angle off the body. This angle is set to bend the open G string exactly 1.5 steps to an A# note when the bridge is pulled back.
This tremolo does not necessarily have to be set floating. If you do not require the bridge to float, follow instructions for the Music Man vintage style tremolo.
If setting the bridge flat on the body per the vintage style instructions, the shim in the neck pocket of your Luke may need to be removed or changed to a different thickness.
This setup only works with 9-42 gauge strings. Using a different string gauge can cause the bridge to sit too high or too low to perform well at this specification.
If a floating bridge is desired using a different string gauge, you can still follow the instructions for setting a rough angle and floating the bridge (through step 6-e), but it will not be set up to bend to a specific interval. It will also require more than the two springs described below.

1. String the guitar
2. Install 2 springs in the back cavity, arranged in a “V” shape.
a. On the springs, the bridge side hooks will use the outer two mounting holes on the bridge block, and the claw side loops will use tabs 2 and 4 on the spring claw.
3. Set the bridge plate
a. Tune up the inner 4 strings (A,D,G,B) until some amount of tension is placed on the trem system.
i. Having both spring and string tension will help keep the bridge from “jumping” on the pivot screws and closer to its natural resting place while performing the setup.
ii. Full string tension is not necessary.
iii. Tension is only placed on the inner 4 strings as to not permanently nick the outer strings while adjusting the pivot screws.
b. Raise or lower the bass side of the bridge plate using the bass pivot screw (4mm hex drive) until there is a small gap between the bridge plate and body at the front of the plate (front is nearest the pivot screw).
i. You should be able to slide a Post-It note between the plate (near the pivot screw) and body without it pinching.
c. Repeat step b on the treble side.
d. Adjust the pivot screws to allow both back corners (nearest the intonation screws) of the bridge plate to rest on the body.
i. Continue adjusting the treble side pivot screw and observe the corners of the plate.
ii. When the treble side screw is tightened into the body, it will reach a point where it levers the bass side corner upward. When the screw is raised out of the body, it will begin to lift the treble side corner.
iii. Adjust the treble screw to where both corners of the plate rest firmly on the body.
iv. Re-check the bass side screw to ensure there is still a gap between the plate and body, and re-adjust if necessary.
e. Move the trem through its full range of motion. If the front edge of the plate contacts the face of the body near the pivot screws, raise the bridge slightly until it moves unimpeded.
4. Block the bridge.
a. Dive the tremolo forward and wedge an object under the back of the bridge plate so the bridge is angled upward.
i. The bridge will be resting on this object throughout the setup, held in place by the spring tension.
b. Use something that won't damage the finish (a folded piece of cardboard wrapped in masking tape works well).
c. The bottom of the bridge plate should sit ~4/32” (3.18mm) off the body, measured at the 90 degree bend near the intonation screws.
d. This measurement is not an exact specification, just a starting point. The final angle will vary based on the results of the setup on your particular guitar.
e. When tuned to pitch, the bridge should be resting on the block. If the block falls out or is easily removed, tighten the spring claw to provide sufficient tension to keep the block in place.
5. Follow the instructions for a hardtail guitar setup
6. Float the bridge
a. With the tremolo still blocked, tune to pitch.
b. Stretch the strings and retune.
c. Loosen the trem claw screws until the bridge block pulls out easily.
d. Pluck the G string, and observe its pitch on a tuner. It will likely be out of tune.
e. Adjust the trem claw to bring the G note back to the correct pitch. When the G is back in tune, the bridge should be back to where it was originally set when blocked.
f. Again, pluck the open G string and pull the trem all the way back until it meets the body.
g. Observe the pitch of the G string with the trem pulled back. It should be near an A#.
h. Adjust the spring/string tension until the open G yields a perfect A# with the bridge pulled back.
i. Make sure all the strings are at the correct pitch before observing the G-to-A# bend.
ii. If the A# note is flat, the bridge plate needs to be higher/more angled off the body. Loosen the spring claw slightly and re-tune.
iii. If the A# note is sharp, the bridge plate needs to be lower/less angled off the body. Tighten the spring claw slightly and re-tune.
iv. It will likely take several attempts to get the bridge at the correct angle to achieve a perfect 1.5 step bend. It is a fine balance between the string and spring tension, and adjusting either one will cause the other to go out of adjustment. Moving the bridge in small, methodical, observable increments is easier in the long run than attempting to make large adjustments.
v. If the adjustment seems to be getting too far off one way or another, tighten the spring claw, re-block the bridge, and reset the angle from the initial base measurement of 4/32” off the body.Factory string setting for standard tuning starts at the bass side 2/32" (1.59 mm) to 5/64" (1.98 mm) and the treble side is 3/64" (1.19 mm) to 2/32" (1.59 mm) measured from the 12th fret to the bottom of the strings. The top of the strings should have the radius of the fretboard when you are looking at the strings in the playing position and by rotating the instrument while at the same time bringing strings into view one at a time. String height is determined by your preference and playing style.

If a string buzzes on the open note to the 5th fret and no higher, more relief is needed in the neck. If there is more buzz from the 5th fret to the 12th fret, the neck needs to be straighter (less relief). Check the string height at every adjustment. If buzzing is present throughout the neck, the string height needs to increase. After every adjustment it is necessary to re-tune the guitar.

The standard float height is measured at 1 1/2 steps on the G-string. If you set this first at 440 tuning, it may make it easier to keep the bridge close to the same angle while making all of the other adjustments. You may want a different amount of float - many players prefer 1/2 or only 1 step of float.

After each adjustment, return to step one, and start again.
 
but, the buzzing is only in that one specific spot for the High E and B strings
With action that low, it could be buzzing because there's a tiny, tiny amount of height difference in a fret, just near those 2 strings. I think they'd have to be perfect to achieve no buzz throughout.
 
Sounds like a truss rod adjustmet is needed. Id bet the neck was set to .005 or something and once it left your tech's area, the neck shrunk and went flat. Happens to me all the time. The above comment of "tink tink" of eyeballing a truss rod adjustment is correct. First fret, last fret and use your thumb and see how much "bounce" you get on or around the 7th fret/middle of the fretboard.

Some people enjoy it to be flat, slightly bouncey, high enough to fly a plane under. Guitar players in general can sense a 1/32nd difference, so you just gotta find your spot.

That’s what I’m thinking. The neck relief is is very low. There is not much space between fret and string I just don’t have the tool to measure it. Would this be a truss rod turn to the left or right? It has a truss rod wheel. I know it’s either clockwise or counterclockwise but is that from the bridge or the fret but
 
Youd want to loosen the truss rod which if the guitar headstock is to the left of you and body to the right, youd turn it counter clockwise or "away" from you. 1/4 turn each time. Retune, measure again. But being a luke, im not 100% on the spoke wheel direction. You wont break something by going the wrong way a 1/4 turn. Itll just get even flatter or youll feel the resistance.
 
It needs to be almost dead flat anyway.
Ive posted this before but if you haven't seen it:

Think I’ve seen this before but will watch again to refresh my memory. Should I try seeing first if the truss rod will fix this or does this need a whole new setup?
 
I've seen quite a few guitars that have the nut slot's way too high. If the nut is too high, you'll often end up needing to lower the saddles too much to try and keep the action over the neck lower. You'll always need more relief over the high frets (12th and up) than the lower frets because of the way the string moves when vibrating. It's motion is the widest at it's midpoint. That can never be lower than the 12th fret for an open string. If your nut height and neck angle are not correct, no amount of bridge adjustment will fully compensate. Excess neck relief can have a similar effect as a neck angle that is pitched too far forward.
