Stratocaster Nut Slot Height Average ratng: 9,4/10 3856 votes

This nut is a bit taller than the stock Strat (MiM) nut. Because of this, the strings are raised higher than they should be on frets near the neck, making open chords cumbersome to play. This small discrepancy will throw your neck action out of whack, for me it required adjusting the bridge saddle, and readjusting string intonation. Ideally, the nut slot height is identical to any other fret. But remember that strings can 'saw' themselves through a nut just through normal use. I ordinarily leave a nut slot a little higher than necessary at first, to allow for the string to cut itself a little lower. Staggered-Height Tuners One way of addressing the retainer problem is by getting rid of them. Staggered height tuners have string posts that get progressively lower — those at the far end of the headstock are lower than those nearer the nut. This means the string's angle increases to compensate for the increased distance from the nut.

This is a “top-down checklist” for the assembly of a solid-body electric guitar.
It can help you to build a guitar with specific sound and playability characteristics. Please read licence and the contribution guidelines before contributing.

Sound and Playability Influencing Factors

Component	Sound*	Playability*
Guitar Neck	+	++++
Guitar Body	+	++++
Guitar Electronics	+++	-
Strings	++	++
Scale Length	+	+
Woods (Body, Neck and Fretboard)	+	+

*influence ( “-” stands for little, “++++” stands for very strong)

For example, for building a solid-body ‘jazz-sounding’ guitar you have to choose (top down by importance):

vintage or jazz pickup with convenient potentiometer and capacitor values
flatwound strings
massive neck, hollow body with wood such as mahagony
shorter scale length

Guitar Necks

Neck thickness, neck width, neck contour and fret wire size affect playability and are a matter of personal taste. Important for good playability is balanced interaction of these components. Thicker neck often creates warmer tone.

usacustomguitars.com/necks - many neck shape and thickness combinations
musikraft.com - additional information for understanding of neck features.

Neck Profile

Neck Profile is the combination of contour (C, U, V , asymmetrc) and thickness (.0750' - 1')

Contour	Thickness	Warmoth*	Fender*	Gibson*
D	thin	Wizard	D Shape
C	thin/medium	Standard Thin	C Shape (AM Std)	Traditional C
C	medium	59 Roundback	Deep C	Round C (1959 LP)
U	thick	Fatback	U Shape (Vintage Tele)
V	thick	Boatneck	V Shape (Vintage 52 Tele)
asymmetrisch	medium	Wolfgang	Modern C

Neck Nut Width and Nut Slot Spacing

Category	Neck Nut Width	e1/E6
Many Fenders from Japan	41 mm (1-5/8')	approx. 34 mm
Standard	42,9 mm (1-11/16')	approx. 35 mm
Acoustic analog	44,5 mm (1-3/4')	35 mm till 37,5 mm
Superwide (Warmoth)	48 mm (1-7/8')	approx. 40 mm

The real e1 to E6 string spread can be controlled not only through nut width, but also by slot spread in the nut. For example, 44.5 mm wide nut can have e1 to E6 distance between 35 and 37.5 mm.

Category	String spacing	e1/E6	e1 to edge	Neck nut width
Narrow string spread	7 mm	35 mm	4.75 mm	44,5 mm (1-3/4')
Medium string spread	7.3 mm	36.5 mm	4 mm	44,5 mm (1-3/4')
Wide string spread	7.5 mm	37.5 mm	3.5 mm	44,5 mm (1-3/4')

Neck Heel Width and Mounting

Most guitar parts manufacturer adopted Fender’s® neck heel and neck pocket dimensions:

56 mm (2-3/16') - Width
76 mm (3') - Length
16 mm (5/8') - Pocket Depth

These dimensions are not a standard. Only careful measurement ensures that your parts will be compatible.

Strat necks have a rounded base to their heel and Tele necks have a squared-off base to their heel, which makes it difficult to interchange the two types of necks across various bodies.

Standard Fender heel mounting is done with 4-Bolt Holes - 1/8' (3mm) diameter (spread of 2' x 1-1/2').

Fretboard’s Radius

Smaller radius means a more rounded shape.

7-1/4' - “Vintage” Fender®
9-1/2' - “Modern” Fender®
10' - Gibson®/PRS®
12' - Ibanez®
16' - Jackson®
compound (10' - 16') - Warmoth® and others

youtube.com - understring radius gauges - video demonstration of three different gauges used for guitar setup and fretwork: standard, notched and understring.

Fret Sizes

Title	Width	Height	Example
Small	narrow	low	vintage Fender
Medium	narrow	high	many Martins
Medium Jumbo	wide	low	many Gibsons
Jumbo	wide	high	moderne Fender
High Jumbo	wide	very high	many Ibanez

Common Neck Head Shapes

6L - Fender Style - left in line
6R - for left-handed
3L/3R - “Gobson Stype”
4L/2R - “Musicman Style”

Tuner Holes

approx. 8,7mm (11/32') - “Vintage Fender Style”
approx. 10mm (25/64' = 9,9mm) - “Sperzel Style”,
approx. 10mm (13/32' = 10,3mm) - “Planet Waves Style”
approx. 10mm on top and 8,7mm bottom - “Schaller/Grover/Gotoh Slyle”

Small holes can be enlarged with a sunk. Big holes can be retrofited by adapter bushings.

Guitar Bodies

The sound of electric guitar depends mainly on the vibration behavior of the string itself and the reproduction characteristics of the pickup. The vibration behavior of the string depends (very little) on wood. The body itself is very thick compared to the neck, that is why the body wood type and form have very limited influence on the sound of electric guitar.

Body Shapes

The shape of an electric guitar can historically be divided into the following categories:

ST (Strat)
T (Tele)
Single Cut (LP)
Double Cut (SG)
Hollowbody
Other Forms

*Wide Humbucker (same as Seymourduncans “Trembucker” or Dimarzios “F-spaced Hambucker”) can be used for guitars with larger sting distance with standard “Humbucker Routing”. Measure from the middle of the high string to the middle of the low string, directly over the pickup. If the distance is greater than two inches or 50mm, go for a Wide Humbucker.

Exact specifications can be found on the manufacturer’s website like:

bareknucklepickups.co.uk - dimensions

In addition to classic HH routing (2X hambuckers), there are the following variants: - SSS (Strat, Nashville Tele)

HSS (Strat Humbucker im Steg, Modern Player Tele)
HSH (Strat),
HS (Strat, 72 Tele)
SS (Tele),
HP90 (Yamaha Pacifica),
S (Tele Esquire),
and some other exotic combinations

Tuning Machines

Tuning Machines Options:

Configuration: 3L+3R (Gibson style), 6-in-Line (Fender style), 4L/2R (Musicman style)
Diameters of bore holes for axis (see chapter Tuner Holes)
Ratio - for 1x winding around the shaft head - 1x rotation necessary.
Larger ratio (1:18 > 1:14) allows finer adjustments.
Standard vs Locking - with locking tuners strings are inserted through the axle bore and fixed by a screw from the outside

Bridges

Guitar bridge has large influence on playability (mainly through string spacing). Wider string spacing is better for finger-picking style, narrow spacing gives easier control when playing leads with distorted tone. Bridge Routing chapter above describes common bridge categories with string spacing specification.

Bridge form and material have also some influence on sound.
Good manufacturers provide detailed product information on their pages:

ABM - indicates that Bell Brass and Steel shape the guitar sound with character, while Aluminum acts largely neutral in the transfer of tone.

Hardware Parts Checklist

Jacks & jackplates
Neck plate (neck-to-body)
Pickguard or pickup mounting rings
Screws for all parts above
Control plate (only for for standard tele)
String ferrules (String-thru Top or Bottom - if you use “string through body” instead of bridge)
String retainers. Happy Little String Trees
Strap holders

For each screw, the hole must be pre-drilled to the core diameter (not outer diameter)

Electronics

Electronics exerts greatest influence on the overall sound of a solid-body electric guitar.

buildyourguitar.com - The Secrets of Electric Guitar Pickups by Lemme - “If you know the resonant frequency and height of the resonant peak, you know about 90 percent of a pickup’s transfer characteristics. Some other effects cannot be described using this model, but their influence is less important”.

Frequency response of a magnetic pickup may look like this

Sound group	Resonant frequency	Resonant peak	Example Pickup
bright	3 - 6kHz	high peak	Fender single coils
powerful	2 - 3kHz	medium high peak	Gibson PAF
mellow	1.5 - 2kHz	low peak	Rolling back tone pot

Following topics change resonant frequency and resonant peak:

Pickup Properties - position and height of frequency peak vary from type to type.
Electronics Wiring Options - Hambucker coils are switched in series by default, switching them in parallel or using only one of the coils will increase resonant frequency and the sound will have more treble.
Potentiometer and Capacitor Values changing provides also simple way to change resonant frequency and peak.
Cable capacitance - longer cable will lead to lower resonant frequency.
Amp input impedance

Pickup Properties

Dimension and product group - see chapter Puckup Routing
Wiring: 1, 2, 3 or 4-Conductor (4-Conductor allowing most flexible wiring)*
Position: Bridge, Neck, Middle
Symmetrical vs asymmetrical connection type
Output: low(vintage), medium, high (vintage used often for jazz and blues)
Passive vs. Active (Active often used for distortion sound)

Classic humbuckers are asymmetrical. They are internally wired in series (i.e. serial - brings more power) in opposite phase (less noise). The current multi-Conductor PUs offer the option of switching the coils differently using push / pull pots, mini switches, toggles, mega switches and rotary switches, and allow broad control over the sound directly on the guitar.

Conductors	Connection Type	Coil Split	Seriell/Parallel	Phase Switch	Example
1x	Asymmetrical	Humbucker Mode	Seriell	No	Shadow AZ48
2x	Symmetrical	Humbucker Mode	Seriell	Yes	Fender Wide Range (Mexico)
2x	Asymmetrical	Humbucker & Single Coil Mode	Seriell	No	Benedetto B6
3x	Symmetrical	Humbucker & Single Coil Mode	Seriell	Yes	viele aktive PUs

Active Pickups Electronics

Active Electronics tries to reduce dependancy from the shielded cable and amp input impedance. However, that needs power to operate, and that’s its biggest drawback.

Custom Buffers (german) - used to decouple the guitar electronics from the sound influencing effects on the shielded cable.

Strings

Depending on following options your sound will be more bright or more mellow:

Construction (Flat Wound/Round Wound)
Material (Steel/Nickel) and
Tension

Most manufacturers use following naming convention to describe tension of string set:

Name	‘e’ site approx.	‘E’ site approx.
Extra-Light	.008	.039
Light	.009	.042
Regular	.010	.046
Medium	.011	.052
Jazz	.012	.054
Baritone	.013	.056

There are also other hybrid sets available - like “Light Top/Heavy Bottom” and “Balanced Tension” combinations.

Guitar Nut Slot Height

Scale Length

A guitar’s scale length is length of string between the nut and the bridge.

Scale has a relatively low impact on sound and playability of the guitar. (Compared with other parameters such as strings or pickups).

Longer scale length sound and playability characteristics:

quick response, crisp attack
transparent sound with well-defined basses and heights
larger finger spread
higher string tension at constant gauge

Shorter scale length sound characteristics:

warmer
more sustain and longer decay

Common Scale Length:
