Geek99 Posted October 14, 2021 Author Share Posted October 14, 2021 (edited) Think I’m going to set relief to 0.4, set action I want and then put relief back on bit by bit Edited October 14, 2021 by Geek99 Quote Link to comment Share on other sites More sharing options...
ubit Posted October 14, 2021 Share Posted October 14, 2021 I must be the only one who doesn't give a hoot about measurements. I do it by feel. Take it down until I get fret buzz then take it back up. Play hard and hear if I get clicking and if so back it off a bit more. I don't have a clue what height in mm or thou or gnats ball hairs it is! 3 Quote Link to comment Share on other sites More sharing options...
Geek99 Posted October 14, 2021 Author Share Posted October 14, 2021 Too much relief means forward bow so (barring tall fret issues) I should get no buzz, I think so what I’m doing is actually the opposite of hell zero’s method Quote Link to comment Share on other sites More sharing options...

lonestar Posted October 14, 2021 Share Posted October 14, 2021 I only have imperial feeler gauges so I set 10-12 thou relief at 7th fret and 2/32in on the G,fretted at the first fret, and 3/32in on the E or B on my five string. Pretty much fender or Sadowsky specs I think. Nut height is 3 thou at first fret with string fretted on the third. 1 Quote Link to comment Share on other sites More sharing options...
Stub Mandrel Posted October 14, 2021 Share Posted October 14, 2021 It's interesting to think about what relief (concave) does. For a given amount of action at the twelfth fret, relief makes minimal impact on the frets near the 12th fret. As you move along the neck towards the nut, the action reduces more slowly than with a flat neck. This reduces buzzing on the lower notes and compensates for the longer the causing greater excursion (the amount the string moves back and forth). As you move beyond the twelfth fret, the action reduces more rapidly than with a flat fretboard. However, the extra stiffness around the neck joint makes this a less significant amount and the rapidly reducing excursion of the strings means this shouldn't be a big issue. Buzzing occurs when either the next fret (or rarely the next but one) is high, or a fret is low. The differences are often on the scale of a thousandth of an inch or even less. Assuming that the frets are decently levelled, buzzing on the higher notes usually means that there is too much neck relief (or there's a 'ski jump' as mentioned earlier). This is particularly likely if buzzing happens in multiple places. Similarly, buzzing on low notes (not open strings, which is a poorly cut nut) means too little or convex neck relief. One way of getting very low action is to set up the bass, then add a little more truss rod tension which will reduce the action by a 'smidgin' but barely affect the string angles on the highest frets. If this does cause a buzz on low notes, put the relief back on. In most cases it will be OK or a little buzz close higher than the 12th fret. In this case you may need to slightly raise one or two saddles, but should still end up with lower action than before. 1 2 Quote Link to comment Share on other sites More sharing options...

Being an engineer i tend to measure things but i have adjusted basses to a point i'm happy with and then i just have to measure it. (its sad but i have no choice 😂) With regards the neck relief my quick way of setting it is when changing the strings i look down the neck without strings and adjust neck to be perfectly straight. When strings are added it draws the neck slightly concave. That would be my approx guide and from there i would then tweak it till i'm happy.................and then measure it cause i'm a sad auld git On hindsight i seem to have different methods of going about it probably dependant on how much time i have available to fine tweak things.

That's a measurement i never check or adjust as i've never known what is correct. My Sandberg has a zero fret so i'm guessing a nut could be adjusted down to approx a fret height.

No fancy tools for neck just hold the guitar and look down the neck to see if it needs a tweak. Ive never had a fear of turning truss rods, Maybe it's because of my mechanical background but I know to turn in increments and that it needs time to settle. Some folks keep turning because they don't see instant results. 1 Quote Link to comment Share on other sites More sharing options...

Dave I think with zero frets, an idea I wish was used more often, the nut height is set for you. My Sadowsky has an “adjust a nut”, ie two little screws to adjust the height. Otherwise it’s nut files and a feeler gauge. Quote Link to comment Share on other sites More sharing options...

I think this is because with a normal fret you have a finger pushing down behind it, which angles the string up a touch. The zero fret doesn't have this. You'll have noticed that fret buzz can sometimes be mitigated by pressing harder or closer to the fret - the same effect, particularly noticeable with heavier gauge strings. 1 Quote Link to comment Share on other sites More sharing options...

I try not to press too hard as i have a nerve end problem on my index finger that feels like someone pushing a needle into my finger if i press overly hard too often. I'm trying to balance playing light with my left hand while digging in. Its an odd thing but when i used to dig in with my right hand i automatically press the strings harder with my left hand.

Geek99 Posted October 16, 2021 Author Share Posted October 16, 2021 (edited) I’ve set the relief to 0.3mm at the 8th and the upper frets are still buzzing unfretted distance at the 12th is approx 2.5mm wondering if the nut is badly cut ?

dmccombe7 Posted October 17, 2021 Share Posted October 17, 2021 (edited) Are you hearing the buzz thru the amp as i have buzzing when i play unplugged but when plugged in nothing seems to come thru the amp. 3rd fret is my lower frets.
