Top Five ways to improve your tone

In honor of the movie (and book) High Fidelity here are the top five ways to make your electric guitar or bass sound better.

5.  electronics- 

this Stratocaster pickguard has copper shielding tape, 250k CTS pots, .022 uf orange drop capacitor, 5-way switch, cloth-covered wire, and Schuyler Dean pickups

This includes pots, capacitors, switches, jacks and shielding.  If you're building a guitar it is a good idea to not skimp on this part and if your doing something like installing new pickups it's nice to use quality electronics to carry the current.

• Shielding- it is important to have shielding grounded properly and surrounding the entire control cavity so that outside electrical interference can't get in.  typically luthiers use shielding paint on the wooden cavity grounded by a lead wire, and shielding tape on the back of the pickguard.  Everything is grounded in this circuit; the pots touching the pickguard shielding, the metal covers on humbuckers, and even the braiding on 2-conductor wire.  A wire is then run from the back of the pots to the bridge grounding the strings.  Ever notice how when you touch the strings the amp stops humming?
• Potentiometers (pots)- 250K pots are warmer and typically used for single coils and 500K pots are brighter and typically used for humbuckers.  No-load pots are louder and make the guitar sound brighter.  There are endless possibilities.
• Capacitors (caps)- The higher the number, the more bass at the zero setting on your tone control.  A .100 uf cap will sound warmer than a .001 uf cap.  Again the possibilities are endless.

4.  The Nut-

This piece of shaped plastic or bone holds the strings in place at the zero fret for the correct string spacing.  Most are made of inexpensive plastic but you can get a nicer tone from bone or even brass for killer sustain!  You can only hear the difference when the strings are being played open of course.


3.  The Bridge-

the Stratocaster tremolo pivots on six body screws and is tensioned by three 

to five springs mounted on the bottom of the body.

There are many different types from the tremolo to the string-thru-body and they all add a bit of character to your guitar.  Brass saddles will typically sound a little nicer than cheaper steel ones.

2.  Pickups- 

Jazzmaster pickups get their fat tone from short "pancake" style 

bobbins and plenty of winds of copper wire.

All pickups really do is change string vibration into an electrical current, but they have everything to do with your guitar tone and how it behaves through the amp.  Good quality pickups like the ones I make will sound clearer and have more voice and character than cheap ones.  High-output pickups will be louder and produce more lows than brighter low-output pickups.

1.  Strings-

And the number one best way to improve your tone (aside from practicing) is to use new, high-quality strings.  Strings with more nickel will sound warmer, and strings with more steel will sound brighter.  You can also opt for flatwounds for an even warmer tone.  Larger diameter strings like .011's (on six string guitar) will be louder and warmer because there is more mass moving for the magnetic pickup to detect.  Old, dirty strings will not perform as well and sound dead so it is important to keep your strings clean and change them regularly.

Giving metal parts that "antique" look

How to age metal guitar parts quick!

I don't know about you, but when I go into a guitar shop I'm always instantly drawn to the rack with all the used gear.  Maybe it's because the beat-up instruments carry a certain mystique, they all have a story to tell.  I want to ask them, "where have you been?" "Who played you?" "Have you been all over the country, or all over the world?" "How long have you been around?" "Have you been in any fights over the years?"  Only the people who owned them know the answers to these questions, and they may be long gone.  When I look at these guitars I get the same feeling I did when I was a kid and I would dig around in the dump full of antiques that was behind my parents house in Maine.  I would find some old farm equipment, or a piece of an engine, or even an old Coke bottle and just stare at it for hours and make up all kinds of stories in my head.  So I think a guitar with some character is a little more interesting than all the shiny turds that were spit out of a factory somewhere overseas.

The first step to giving a guitar some character is rust.  Some people might cringe at the idea of intentionally rusting their precious guitar, but it is fairly easy to do and doesn't effect the playability of a guitar.  You DO NOT, however want to intentionally rust parts that effect the adjustments like action and intonation, for example, tuners and bridge adjustment screws!  So how do you make rust?  Salt!  If there is one thing I learned in Maine it's that salt will rust your car faster than anything.  In the winter they salt the roads to melt the ice, it's good for the traction, but bad for the cars.  You would be lucky to find any cars over 10 years old still on the roads in Maine.

So to rust my metal guitar parts I first remove them from the guitar and put them on a piece of plastic or in some sort of container.  I mix a couple teaspoons of salt with some warm water and mix it up with a paintbrush and then brush it on the parts as if it was paint.  Then I simply leave them outside and let Mother Nature do the rest.  I let them sit there for a couple of days and really let the elements beat on them, reapplying the salt water mixture as needed. 

In a couple of days I rinse off the parts with water and dry them with a paper towel.  Now my guitar has the look of one that's been played, sweat on, and beaten up for years!

What is 'scatter-winding' anyway??

Many high-end pickup manufacturers like to boast (myself included) that their pickups are "scatter-wound," but many people don't really understand what this term means.  In fact the whole art of winding pickups is quite foreign to a lot of people, even if they play guitar.  Quite simply, scatter winding is a method of making pickups that results in a unique and beautiful sound.  In this post I'll take a stab at trying to explain the principles of this method.

All electric guitar pickups use the same basic design, they are simply magnetic polepieces wrapped in very thin copper wire.  The polepieces generate a magnetic field that the string vibrates in, and the copper coils turn that vibration into an electric signal. 

In the '50s, electric guitars started getting extremely popular.  Humbuckers, used primarily in Gibson guitars, used a uniform wind made on a machine; and single-coils, used primarily in Fender guitars, used a scatter-wound coil made by hand.  Technically you could use either method for either type of pickup, but it is widely believed that single-coils sound better scatter-wound.  Tension also matters when winding a pickup, looser winds typically sound clearer and better.

When I first started winding pickups I didn't understand that the way in which you wind the pickups actually has an effect on the tone.  It made sense to me that the quality of wire you use, the number of turns, the quality of the magnets, and the strength of the magnets all played a part in the overall tone.  But I figured you would need some sort of ultra sensitive computer to hear if they were scatter-wound or not.  I made a couple of pickups by just guiding the wire back and fourth in a very even manner.  I made a couple variations of these and tested them, then I made a set of pickups using a scatter-winding technique.  The first thing I noticed was that the resistance (electrical output measured in ohms) of the pickup had dropped significantly.  When I installed them and tried them out I was amazed!  I was hearing details that I had never heard before, there was more treble and harmonics than I had heard from my earlier pickups.  The video below shows me scatter winding a pickup.  The wire is as thin as a human hair so you can't really see it, but you can see how my hand is moving to get an idea of how it's done.  It also helps to be blasting Pink Floyd while you're doing this for 15-20 minutes per coil.

When coils are wound on a machine, each consecutive wind is very close to the last wind.  when you scatter-wind a pickup the idea is to put lots of space between each consecutive wind, this lowers the distributed capacitance of a pickup so that more treble and detail get through.  Your tone control on your guitar has a capacitor on it, as you turn that control counter-cockwise it uses more and more of that capacitor to bleed off highs to the ground, and the result is you hear a darker guitar tone.  Scatter-winding does just the opposite, it gives the pickup more treble.  This sounds really good on single coils because they have a very open sound to begin with, extreme highs and extreme lows, a lot of the guitar's natural tone and character comes through.

When I'm scatter-winding a pickup, I try not to follow any sort of pattern and I move the wire randomly across the bobbin.  Machines are not good at this because they are programmed to do things very neatly.  I suppose you could program a robot to mimic the motion of the human hand, but that wouldn't exactly be cost-effective.  The human hand is a really good tool for this because it's hard for us to do things in a consecutive pattern.

Update 08/04/2010

You can also scatter-wind by simply guiding the wire back and fourth faster across the bobbin, thus putting more distance between each wind.

Scatter-wound pickups are more expensive because they have to be made by hand.  It also makes the pickup more unique because you can never exactly replicate what you did before, so each pickup has its own tonal character.  When Fender first started out as a company, all of their pickups were wound by hand, they are considered by many to be some of the best sounding pickups in the world.  Today they make thousands of guitars a year so naturally it doesn't make sense for them to hand-wind each pickup, but there are a few other winders out there like myself who still hand-wind every single pickup.
