*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

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.

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

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.

graphtech - sizing guide and pre-slotted nuts

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").

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

lutherie.net - provides an excellent manufacturer/sizes overview.

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

• 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.

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.

music.stackexchange.com - how much does electric guitar's body physics affect the tone and playability.

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

• Flat Mount Hardtail (Strat/Tele/Schaller)
• Tremolo (Strat)
• Tune-O-Matic (Gison)
• Other (Jazzmaster®, Jaguar®, Bigsby®, Kahler®, Line 6, etc)

*Wide Humbucker (same as Seymourduncans "Trembucker" or Dimarzios "F-spaced Hambucker") can be used for guitars with larger string 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 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

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

The following list summarizes the accessories that are required to complete your own guitar building project

• 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. see premierguitar.com article about design and construction
• Strap holders

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

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

Following topics change resonant frequency and resonant peak:

• Pickup Properties - position and height of frequency peak vary from type to type.
• Sound Control With Switches - 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

• 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)
• D.C. Resistance: indication how much output a pickup will have
• E.Q. chat: A general idea as to the Bass, Mids and Treble.

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.

• Coil Split - "Single Coil Sound"
• Seriell/Parallel Schaltung - "double Single Coil Sound"
• Phase-Switch - "Out of Phase Sound"

SP = Single Pole, DP = Double Pole, DT = Double Throw

Active Electronics tries to reduce dependency 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.

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:

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

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:

• 572 mm (22.5") or shorter - 3/4 & some travel guitars
• 596,9 mm (23.50") - Fender Jazzmaster/Jaguar guitars
• 629 mm (24.75") - many Gibson guitars
• 635 mm (25") - many PRS guitars
• 648 mm (25.5") - many Fender guitars
• 650 mm (25.5) - typical classical guitars
• 686 mm (27") or longer - Baritone guitars
