Buying an electric guitar, part 3 – Assessing a guitar’s condition

How do you assess the condition of an instrument?

In my view, the condition of any guitar can be gauged by dividing up any possible issues into three groups:

Group 1 – Things that can be changed/corrected easily:

++ truss rod settings

++ dead strings/”wrong” string gauge

++ intonation

++ string height (action)

++ pickup height

++ pickup model (if no woodwork/modification is required)

++ worn-out tuners (if no woodwork is required)

***

Group 2 – Small and slightly bigger issues that a qualified repairperson can solve:

++ a cracked top nut

++ string slots in nut too deep or not deep enough

++ a faulty vibrato system

++ worn frets or high/low frets

++ crackling controls

++ faulty switches

***

• Group 3 – Issues that are difficult and/or expensive to repair:

++ a badly warped neck (so-called corkscrew)

++ a set neck that is out of alignment

++ a broken truss rod

++ unrepaired (or badly fixed) cracks in the wood (for example a broken-off headstock)

++ a botched DIY ”customisation”

Would you buy a guitar from Pete?

****

Here’s one way of assessing the condition of a guitar systematically:

• Tune the instrument and play it for a minute or two. You’ll get an idea of the current set-up, as well as of the general condition and sound of the instrument.

• Is the neck correctly aligned to the body (especially important in set-neck instruments)?

Look at the distance of the e-strings to the fingerboard edges at the 14th fret. If both e-strings are approximately the same distance from the edge of the fingerboard, you’re good to go.

• The truss rod setting (aka relief):

Press the bottom E-string down simultaneously at the 1st and 14th frets (you can use a capo at the first fret), and use it as a straightedge. Take a look at the string at the 8th fret; there should be a small gap between the top of this fret and the E-string – that’s what we call the relief. If the gap is around 0.5 mm, the truss rod is set as it should be. Check the treble e-string in the same way. If there’s a substantial difference between the relief at the low E and the treble e, you’re most likely looking at a warped neck.

If the truss rod setting is not ideal (too tight = no relief; too loose = relief greater than 0.5 mm) you should ask the seller to adjust the truss rod for you.

• Check the nut slots:

Each string is pressed down in turn at the 3rd fret. The string should now be resting on the second fret. Look for a small gap between the 1st fret and the string you’re pressing down. Using a regular 009- or 010-gauge set, there should be a tiny gap beneath the treble e-string and the first fret (when fretting the string at the third fret), just about large enough to fit a sheet of printer paper in there. Because the bass strings need more clearance to vibrate freely, the gap between the first fret and the bottom of each string increases slightly going from the top e-string to the bass E-string.

If the nut slots aren’t cut deep enough, the guitar will be hard to play, and sound badly out of tune in the lowest (open) positions, regardless of action settings and intonation. A luthier will be able to correct the matter for a small charge using a set of special nut files.

If the string slots are too deep (= the strings rest on the first fret, when pressed down at the third), a nut replacement will be in order (except with locking nuts that can be shimmed). Nut slots that are too deep will result in rattling open strings, even if the action and the truss rod have been adjusted correctly. Note: You should check for string rattling using clean amp settings. Playing the guitar unamplified might make you whack the strings harder than necessary.

In most cases replacing a nut is an easy procedure for a repairperson.

• The condition of the frets:

On a used guitar, slight wear marks on the frets are the result of normal use, and this light wear won’t cause any problems.

If the frets are very worn (like the ones in the picture below), you should take the cost of a fret dress (or even a complete refret) into consideration, and maybe try to get the seller to lower his/her asking price.

Refretting bound fingerboards is more complicated and time-consuming than dealing with unbound ’boards, which is usually reflected in the cost. Ask you luthier.

• Check the bridge:

Are all the screws and bridge saddles in working order? Is there ample scope for intonation adjustment?

If the guitar’s set-up is unsatisfactory – the action may be too high or too low; the intonation may be off – ask the seller to adjust the guitar for you before making a buying decision!

• Check the electronics:

Play around with all controls and switches – is everything working as it should? Do all the pickups work?

Scratchy, crackling pots and faulty switches are quite easy for a luthier to exchange. If we’re talking about a new guitar, the shop should take care of this before you buy. With a pre-owned instrument, you will have to take care of the repairs. Note: Replacing electrical components and pickups in semi-acoustic and archtop guitars is generally much more complicated, which will be reflected in the luthier’s quote.

• Check the vibrato:

Does the vibrato (aka the tremolo or the whammy bar) work as it should? Are all the parts in working condition, or are you faced with rusty screws or even broken parts? Is there ample scope for action and intonation adjustment?

If the vibrato bridge looks very worn, or if there are structural problems, like a broken off (or loose) bridge post, you might be facing a complete replacement or a costly repair.

• And finally: Plug the guitar into an amp, and play it some more. Listen to the sound of the instrument. Check its playing feel, its ergonomics, and make a final assessment of its overall condition.

• Based on this checklist (and any possible issues you might have found) you should ask yourself two questions:

  1. Do I like this instrument?
  2. Do I think this guitar is worth its asking price?

The Fender Telecaster – tone at the expense of intonation?

Why do we need intonation adjustment?

On string instruments, the fret spacing along the fretboard is calculated according to a mathematical formula. This formula is theoretical, though, and doesn’t take into account variables, such as string tension (tuning), string thickness (gauge) and string height (action). These variables make the actual pitch of a string, which is pressed down against a fret, deviate from the theoretically correct pitch. To compensate for this pitch offset, you need some sort of intonation adjustment that sets the correct intonation (or octave compensation) for each string.

Martin_D-42K_2006_brdt_opt

On acoustic guitars correct intonation is achieved by an angled bridge saddle, often carefully shaped to fine-tune the compensation further.

Jazz guitar bridge

Early electric guitars were basically modified archtop acoustics, which carried on using traditional rosewood (or ebony) archtop bridges with carved ”steps” presetting the intonation. Overall intonation adjustment was carried out by moving the whole bridge carefully closer to (or further away from) the neck.

Fender 52 Reissue

The advent of the – much clearer-sounding – solidbody electric guitar necessitated a more precise approach to the problem of intonation adjustment.

52 Tele Bridge

Leo Fender’s novel Esquire/Broadcaster/Telecaster-bridge featured a mounting plate for the bridge pickup, as well as individual action adjustment for each string, and octave compensation in string pairs.

Fender’s Telecaster bridge assembly plays a huge part in this model’s distinctive, twangy tone, laying the foundation for the model’s classic status.

Over the course of the 1950s and 60s, Fender experimented with different saddles – smooth brass, smooth steel, threaded steel, and steel saddles with a single notch per string – but the basic, three-saddle formula stayed firmly in place. You got fantastic tone, but not perfectly spot-on intonation.

****

70s Fender six-saddle

Twenty years after the original launch of Fender’s first solidbody electric, things had evolved.

In 1952 the original three-saddle bridge was less of a compromise, because the regular string sets of that time (012s or 013s) had a wound g-string. With a wound g-string the biggest step in intonation adjustment was between the b- and the g-string, and, as they were catered for by different saddles, a good, working compromise could be found.

By the late Sixties, ”slinky” string sets with plain g-strings had become the norm. This shifted the intonation step between the highest wound string and the lowest plain string onto a single, rigid bridge saddle (for the D- and g-string).

Fender retained the traditional three-saddle bridge on its standard Telecaster, but introduced six-saddle bridges on many of its new models in the Seventies. Pictured above is the six-saddle bridge from a (second version) Custom Telecaster (introduced in 1972).

Although this bridge finally offered perfect intonation, some players criticised this type of bridge for ”sounding” thinner (or brighter) than the original version. This might also have been due to changes in the precise specifications of the bridge pickup at that time, though.

Hipshot 6-saddle

Modern Fender 6-saddle

More recent six-saddle designs by makers like Hipshot, Gotoh or Fender are based on a thicker bridge plate. These are perfectly serviceable, modern designs, which offer precise intonation. Many Tele-anoraks still steer clear of these bridge types, however, because the more rigid bridge plate tends to tame the bridge pickup’s twang noticeably.

****

Another approach to better intonation on a Telecaster is to keep the twang-enhancing three-saddle ashtray bridge in place, but modify the saddles.

Joe Barden angled

Pickup specialist Joe Barden came up with angled brass saddles in his design for the late Tele-master Danny Gatton.

Wilkinson

Graph Tech

Wilkinson’s and Graph Tech’s designs have two different, preset jump-off points per saddle – one for each string.

These three approaches (Barden, Wilkinson, and Graph Tech) work very well in providing good intonation, while keeping the Telecaster-tone intact, as long as you use string sets with a plain g-string.

pivoting brass saddles

Mastery stainless steel

If you want to retain your three-saddle twang, but want to have more freedom in choosing your string gauges, the best way to go are saddles with an angle adjustment. Good examples are Wilkinson’s replacement brass saddles (above), or this stainless steel Tele-bridge by Mastery.

How come that the vintage-type Fender Telecaster, with all its intonation flaws, is still in production and still very successful? The answer is that people have always been creative in working out solutions to design shortcomings.

In the Telecaster’s case this means finding a way to ”sweeten” the guitar’s slightly flawed intonation.

Here are three (of a myriad of) possible approaches:

1.) The fifty percent approach

After you’ve put on a set of new strings, use your digital tuner to set the (12th fret) intonation correctly for both E-strings, as well as the g-string (I call them the most critical strings). Then tune your guitar by tuning the open E-strings and the g-string to pitch. The remaining three strings (A, D, and b) are then tuned, so that the pitch at the seventh fret is correct (giving you E, a, and f#).

The A-, D-, and b-strings will be a little off in their intonation going up (or down) from the seventh fret, but overall the pitch will be much sweeter, than if you had tuned these strings to their correct open string pitches. You can then fine-adjust your sweetening by ear, using first position chords as a reference.

2.) Tuner sweetening

After you’ve put on a set of new strings, use your digital tuner to set the (12th fret) intonation, so that each string pair is slightly off in an approximately even way. With the E- and A-pair this would mean that the E-string’s intonation comes out slightly sharp, while the A-string’s intonation is a tiny bit flat. The next pair would see the D-string a bit flat, while the (plain) g-string is a tad sharp. The last pair would have the b-string a bit sharpish, with the e-string a little flat. Then tune the guitar by tuning all strings, so the pitch is correct at the seventh fret.

Now all strings will be a little off in their intonation going up (or down) from the seventh fret, but overall the pitch will be much sweeter, than if you had tuned them to their correct open string pitches. You can then fine-adjust your sweetening by ear, using first position chords as a reference.

3.) Sweetening to the A

After you’ve put on a set of new strings, use your digital tuner to set the (12th fret) intonation, so that each string pair is slightly off in an approximately even way. With the E- and A-pair this would mean that the E-string’s intonation comes out slightly sharp, while the A-string’s intonation is a tiny bit flat. The next pair would see the D-string a bit flat, while the (plain) g-string is a tad sharp. The last pair would have the b-string a bit sharpish, with the e-string a little flat. Then tune your guitar by first tuning the open A-string to pitch. Next, tune all the other strings by ear, using the A-string as your reference:

• E-string at the fifth fret against open A

• D-string at the seventh fret against open A (or A-string 12th fret harmonic)

• g-string at the second fret against open A (or A-string 12th fret harmonic)

• b-string at the tenth fret against open A (or A-string 12th fret harmonic)

• e-string at the fifth fret against open A (or A-string 12th fret harmonic)

You can then fine-adjust your sweetening by ear, using first position chords as a reference.

****

Remember, none of the above tuning tips is set in granite. Tuning and intonating a three-saddle Telecaster is a dark art, and most players have developed their own way of sweetening their guitar’s intonation. Let your ears be your guide!

Can I play Metal on a Telecaster?

Of late there’ve been repeated questions about the venerable Telecaster’s suitability for Metal-playing, so I thought I should respond:

Starting in the Eighties a myth has grown that Hard Rock and Metal can only be played on guitars specially designed for these types of music. In reality there isn’t a special sub-species of instruments – if you look closely enough most ”Metal guitars” have their roots in classic models, most derived in some way from Gibson’s classics.

A Fender Telecaster is as suited for Metal as most other solidbody electrics – as long as you don’t plan on using a strictly vintage-type Tele.

A vintage Telecaster’s ”problem zones” for hard ’n’ heavy are its singlecoil pickups, its ashtray bridge, its small frets and small radius (= very convex) fingerboard.

Singlecoils suck in way too much extraneous electromagnetic noise (buzz and hum) to be of any practical use in a high-gain environment. Additionally, the metal cover on the front pickup as well as the grounding plate on the back pickup tend to induce howling feedback at extreme volume and gain settings.

A vintage Tele’s bridge is problematic when it comes to spot-on intonation, because it only features three bridge saddles. Furthermore, the relatively thin metal plate the bridge is made of also is a regular culprit when it comes to high-gain howl.

A small fingerboard radius coupled with small frets makes string-bending noticeably more difficult.

****

The easiest way to deal with these problems is to select a Tele-model that’s already equipped with a six-saddle-bridge, humbuckers and a flatter fingerboard with bigger frets. Good examples are:

Sopiiko Telecaster-malli metallimiehelle?

Viime aikoina kysytään yhä useammin Telecaster-kitaran sopivuudesta Metal-musiikkiin, niin ajattelin vastata siihen:

1980-luvulla alkoi syntyä sellainen käsitys, että Hard Rock- tai Metal-soittamiseen voi käyttää vain juuri siihen tarkoitukseen sunniteltu sähkökitaraa. Todellisuudessa ei ole olemassa varsinaista Metal-kitaran alalaji, vaan käytännössä kaikilla Hard Rock -soittimilla on esi-isä jossain klassikkomallissa – usein ne ovat Gibson-klassikkojen johdannaisia.

Fender Telecaster sopii alustana yhtä hyvin Metal-soittimeksi kuin useimmat muut lankkukitarat, jos vain ei ole tarkoitus vetää täyttä moshausta vintage-tyylisellä mallilla.

Vintage Telen ”ongelmakohdat” tässä yhteydessä ovat yksikelaiset mikrofonit, laatikkomainen talla, ohuet nauhat ja hyvin kupera otelauta.

Yksikelaiset mikrofonit ottavat vastaan aivan liikkaa ulkoista huminaa ja hurinaa, minkä takia suurilla gaineilla soitetaan yleensä humbuckereilla. Tämän lisäksi etumikrofonin kuori ja tallamikrofonin alla oleva metallilevy aiheuttavat kovilla volyymillä usein feedback-ulinaa.

Vintage Telen tallassa piilee kaksi ongelmaa: intonaatio ei ole koskaan täysin kohdallaan, koska on vain kolme tallapalaa, ja suhteellisen ohut metallilevy aiheuttaa myös itse jonkin verran feedback-ongelmia.

Pienet nauhat ja otelaudan voimakas kaarevuus taas tekevät kielten venytyksistä vaikeaa.

****

Helpoin tapa ”korjata” näitä ongelmakohtia on hankkia jo valmiiksi nykyaikaistettu Telecaster-malli, jossa on kuudella tallapalalla varustettu talla, humbuckerit ja loivempi otelauta isoimmilla nauhoilla, kuten esimerkiksi:
