How to Pick the Right Strings for your Cigar Box Guitar

One of the most frequent questions we hear from new cigar box guitar builders is what strings they should use on their cigar box guitar, and how they should tune it. This can be very mysterious for a builder, especially folks without a background in music. While it is often said that there are no rules when it comes to building CBGS (and that is often true, which is one of the great things about this hobby), it can be frustrating to hear when you just want a simple answer to a question. In this article, we’ll try to demystify some of the theory behind strings and tunings, and also give some straightforward, clear answers for those who just want to know what to do.

Southbound Strings Open G 3-string SetFirst, we’ll give a clear answer for those of you who just want to know what to do: at C. B. Gitty Crafter Supply we consider a “standard” cigar box guitar to be a 3-stringer with medium-gauge acoustic strings tuned to either Open G (for slide playing), or G-B-E for fretted playing. The strings used are equivalent to the three highest-pitched strings on a standard six-string guitar, and the scale length of the instrument (the distance from the nut to the bridge) is around 25 inches.

This happens to be the most popular set of CBG strings we sell in our shop – our C. B. Gitty 3-String Acoustic Medium Open G/Standard Set. If you are building your first cigar box guitar and have no idea what to do or what you need, start with these strings. These strings are based on a “medium” weight set sold for a standard 6-string but include only the 3 highest-pitch strings (the smallest/lightest ones) from the pack, so you don’t have any leftovers. It can be tuned either in “Open G” for slide playing (G-B-D) or if you have a fretted neck it can be tuned like the 3 highest-pitch strings of a standard guitar (G-B-E).

This “standard” tuning will allow you to utilize partial chords that you might know from a standard guitar. We’ll be posting a separate article on the basics of playing soon, but for now, we’ll just say that these three strings correspond to the 3 rightmost strings on a standard chord diagram, so you can play most guitar chords by just fingering those strings. A “G” chord becomes a one-finger chord, with the E string fretted on the third fret; A “C” chord becomes a 1-finger chord with the B string fretted on the first fret, etc.

Now the Choices Begin

Once you are ready to move beyond the 3-string Open G/Standard Guitar set listed above, the choices start. These choices range from string weight (from heavy to extra light) to the number of strings (anywhere from 2 to 6), to string type acoustic vs. electric (bronze wound vs. nickel wound). There are even more advanced choices that can be made, such as stainless steel instead of plain steel, but we’re going to keep it simple here in this article and deal with each of these choices in turn.

1. String Weight

This refers to how “heavy” the strings you decide to use on your build are. If you look at standard 6-string guitar sets, you will quickly see that they are offered in a range of weights from heavy to extra light, with the middle-of-the-road choice being (usually) referred to as “medium”. The weight of the string really refers to the gauge, or thickness, of the strings in the set. A heavier set will use thicker, fatter strings, and a lighter set will use thinner, lighter strings. The idea here is that larger strings have to be pulled tighter to get them to pitch; this extra tightness creates more tension and downward pressure on the soundboard, which results (up to a point) in more volume from the instrument. Of course, this can be taken too far, and if the string tension gets to be more than the construction of the instrument can handle, horrible things accompanied by the sound of cracking wood occur.

For cigar box guitars, our recommendation is to stay somewhere in the medium to the extra light range for acoustics and in the “light” range for electrics. The main thing to consider when deciding between medium and extra light is the strength of your neck and how many strings you are going to have. String tension is what causes necks to bow. So if you have a pine 1×2″ neck with no bracing, truss rod or laminated fretboard, and you want to put a set of 6 standard guitar strings on it, you are going to end up with something that looks like a hunting bow, if not two pieces of broken neck.

For softwood necks (which is really not recommended to begin with), you will want the lightest strings you can get. For hardwood necks on 3 or 4-string instruments, medium should be fine (though tending towards the lighter side is usually recommended). If you have glued on a laminated fretboard, then your neck will be even stronger. If you have put in a truss rod, then you should be good to go with anything.

As with most things CBG-related, the general rule of thumb is: try it and see. If you put on medium strings and your neck bows too much, take them back off and use extra-light strings. A good tip here is to never trim your strings off at the tuners until you are absolutely sure they are the right strings. Leaving that extra length means you can take them back off and use them on another build.

We carry all of our acoustic string sets in both medium and extra light.

2. Number of Strings

The vast majority of Cigar Box Guitars are made with 3 or 4 strings – you really need 3 strings or more to get the harmonic depth and range of pitches that makes a sound people associate with the concept of a guitar. One-string instruments are really more technically known as diddley bows, two-string instruments can be very interesting but are still pretty harmonically limited. Five string instruments are definitely possible but aren’t done that often, and six-string instruments generally are more advanced due to the higher string tensions and bracing requirements, so our focus here will be on 3 vs. 4 strings.

A lot of new CBG builders and players ask: what’s the difference? Why choose 4 strings over 3, or vice versa? Which one is better? The answer is: it’s up to you. Really it comes down to personal preference, but we will do our best to present some of the plusses and minuses of one versus the other.

Three-string CBGs have the benefit of being cheaper parts-wise, easier to build and less complicated to play. Less strings means less tension on the neck and risk of bowing; it means easier chords, with many requiring just one or two fingers; it means more harmonic simplicity to help a newer player keep from getting overwhelmed. And, it is seen by many (but not all!) CBG afficionados as being the more traditional and historically accurate setup. Whether or not you buy into that is up to you.

Four-string instruments present more possibilities when playing, whether you are playing slide style or fretted style. That extra string allows more advanced chords, richer and more complex harmonies, and more interesting tuning options (such as adding a 7th to the tuning so you have an open seventh chord for blues playing). The trade-off is that not everyone WANTS more complex playing options. Also, that extra string adds to the overall tension on the neck. Four strings is in the gray zone when it comes to unbraced necks – in other words, a neck without a truss rod. Generally you will be OK with an unbraced neck with four strings so long as you use a good strong hardwood like oak or maple. Gluing on a fret board made from another hardwood definitely helps strengthen up the neck as well. Usually we would recommend light or extra-light strings on an unbraced 4-string neck.

So in summary, the only real difference between 3 and 4 strings comes down to playing style. If you are a beginning builder or player, our recommendation would be to start with a 3 string and then think about a 4 (or more) string later.

We carry a nice selection of both 3 and 4-string sets in our online store!

3. String Winding Type: Acoustic vs. Electric

First, a bit of theory: let’s start by defining what we mean when we say acoustic and electric. By acoustic we mean builds that either have no electronic pickup in them at all (true acoustic) or those that have a PIEZO pickup only. Piezos react to (and pick up) acoustic vibrations in the instrument, so technically they are still an acoustic pickup.

By electric pickups, on the other hand, we mean a magnetic would pickup like the single and double-coil ones you find in a standard electric guitar. These pickups are comprised of magnets wrapped with copper wire, and instead of picking up acoustic vibrations they are excited electromagnetically by the steel in the strings.

Standard acoustic strings will work fine for both true acoustic CBGs as well as those that have a piezo pickup. The standard plain steel and bronze-wound strings do a great job of producing the soundboard vibrations that create the acoustic guitar sound we all recognize. We sell a variety of acoustic string sets for various tunings, in both medium and extra-light gauges, for both three and four-string CBGs. Nickel-wound electric strings will work fine with piezo pickups.

For magnetic electric pickups, however, a special type of wound string is needed. These strings consist of nickel windings over a steel core, which allows the magnetic pickup to “hear” them. Standard bronze-wound strings also have a steel core, and will generally also produce sound on a magnetic pickup, but many professional players prefer nickel-wound strings on electrics. In our experience it really comes down to a matter of taste and aesthetics.

The decision of whether to go true acoustic, piezo acoustic or true electric is one of taste and playing style, and could be the subject of an entirely separate article. For now, this summary should give you a basic starting point for understanding the differences.

We carry both three and four-string electric sets in our shop for those of you interested in exploring this option.

That completes our summary overview of choosing strings for your CBG. There are of course almost endless choices and variations you can make when it comes to strings and tunings. The best way to approach it, in our opinion, is to just start trying things. Try some different sets on your build, get an idea of what extra-light strings sound like as compared to medium strings. Try out an open D and see how it is different from the Open G. Or take a look at a standard set of guitar strings and try some different combinations to see what you can come up with. We will be adding more articles soon that cover some more advanced concepts related to different tuning, fretting and scale length concepts.

  1. Converting a 3 String CBG into a 4 String is just a simple matter of adding one more hole for the 4th String, & an additional tuner etc: cause it might be great for people who wanna move onto a 4 String but don’t wanna make a new instrument. Converting a 3 (or 4) String CBG into a 5, 6 (or more) String CBG would require making a new neck. I’m going to be doing that one w/ my father when his arm is fully healed since he’s back from his surgery.

  2. I’d convert my 4 Stringer into a 6 Stringer by modifying the neck, & what I do rather cleverly is tune the instrument a Half Step lower to Eb Standard to prevent it from collapsing. Say has anyone ever played a Cigar Box Guitar tuned down a Half Step from Standard Tuning?

  3. One of our pre-wired harnesses would be great. We have a 6-string with volume and tone that starts at $11.99

  4. I am building my first single string Diddley Bow. What magnetic pickup would you recommend for a starter?

  5. Hello there, I just came up with plans on the 4 to 6 String CBG conversion cause instead of making a new Guitar I’d just have my original one upgraded.

  6. Int6 String Cigar Box Guitars are missing a really interesting part, a Built in tuner because once you start going to 5 (or more) strings a built in tuner will keep it all in tune. Converting a 3 or 4 String CBG into a 6 String might require a special conversion neck. One instrument that we’re missing is a Nashville Tuned Cigar Box Guitar. It’s a 6 String Cigar Box Guitar (6 single Strings) strung with the High Strings from a 12 String set (EJ38H by Daddario) & it produces an interesting sound. Interestingly if you take Nashville tuning & replace the B String with an Octave4Plus .006 High B string, you’ll be in “New Nashville Tuning” which is an upgraded version of Nashville Tuning. It kinda reminds me of this song: I wanna wash my hands, which is an updated version of a Beatles classic from JoJo Rabbit I wanna hold your hand.

  7. Wait a second, that idea of turning a 4 String Cigar Box Guitar into a 6 Stringer actually reminds me of a person who turned his 4 String Bass into a 6 String Bass aka Bass VI: & when he did it, he had to go down to really light gauge Bass VI strings so that way the tension wouldn’t be too much. It also reminds me of a person who turned his 4 String Bass into a 5 String: & he had to switch out the Jazz neck with a much thicker P-Bass neck cause a thicker neck can handle more tension. It even reminds me of a person who recycled a Smashed up Guitar & turned it into a Mandocello:

  8. Unfortunately we don’t know of any plans for the conversion you want to make Oscar. In general I wouldn’t recommend trying to make a cigar box guitar that was designed for 4 strings into a six-stringer. It would be better to start (or commission) a new build specifically designed for six strings.

  9. After playing on 4 Strings for a long time, I thought of converting it into a 6 String so I can play it like a normal Guitar. I’d like you to make me 4 to 6 String Cigar Box Guitar conversion plans. It’s getting a truss rod, & more bracing so it can support more tension. I’m going to have to use the lightest gauge of Strings (8’s, or even so 7’s which are really thin) so that way the tension wouldn’t be too much. The 3 (or 4) string to 5 (6 or more) String conversion for a Cigar Box Guitar reminds me of this song: Nutbush Sitar Limits which is Nutbush City limits on Sitar. It’s a tribute to Naya Rivera who sadly died of Drowning. RIP Naya Rivera.

  10. Hi
    Been playing for about 6 months now on the Hinkler fretless CBG! Using your parts, I would like to build a fretted , 25″ scale CBG. Based on this info and what i already have, what set of strings do you think would work for this build?
    By the way, love this website! The free music , advice , etc is very helpful for us beginners!

  11. I have a McNally D-Chromatic strum stick and would like to change it to the same tuning as my cigar box I made from your kit.
    Can you recommend string sizes as low as possible that won’t hurt the instrument. I would like to play it in open g tuning, their seems to be more music out there for g tuning than d tuning. I realize I could capo up 5 frets but I want to stay away from that. A beginner.

  12. I recommend checking out one of the many sites devoted to dulcimers to learn more about the many different ways that they can be strung, tuned and played. A cigar box dulcimer really only differs from a traditional dulcimer in that it uses cigar boxes for the body.

  13. I am a rhythm guitar who has been interested in building a guitar for quite awhile. I recently ran across you cigar box Web site, and thought it would be fun to start out with a cigar box dulcimer. I’m not sue as to whether I should try 3 strings or four. I do prefer the chromatic scale because I enjoy playing chords. Are there chord charts for three and four string dulcimers?
    Thank you kindly,
    Terry Roszatycki,
