Here are tuning frequency in Hz which to me helped to know which-octave. :  Shown; Zentapper Tuning, (but likely works for Megatar also[smile]
bass-bottom-fourths, player's point of view (thinnest bass string to your left.)  
 
Chart:
 
  On Fret 2, Chromatic note, Frequency in Hz.

  D3   A2    E2   B1   F#1    C#1     E4   B   F#3    C#3   G#2   D#2

  147  110   83   62   46     35      330  247  185   139   104   78

            BASS STRINGS               MELODY STRINGS
  THIN STRINGS          THICKEST      THIN STRINGS      THICKER
 

I use a (local saved copy) of the excellent "listening" tuner on seventhstring (link here)   (shhh, it's a secret - use FireFox won't work in chrome) which also shows frequency in Hz (not simply a letter note.)  

This helps me, a beginner, to know if my "G" is in the right octave and is not accidentally one whole octave too low, which is important for us-beginners that can't rely on any memory of what the tension should feel like, as we're that new.    Or, risks of accidentally one whole octave too High and... [ SNAP ] string breaks!!

Thus... I hope this helps someone! 

Tuners that merely show "letter" not as useful, especially when octave could be WAY off such as: 
  1. During string changes
  2. Arrivals of new guitars

If you're using some other string order, then help adjust listed
 string order as needed and reply here the use case, as it may help that next new person.

Here is a complete pitch-vs-frequency table, covering the range of essentially all instruments:

That's kind of amazing, that instruments go from about 40hz through about 1100 hz only, when humans can hear 20 hz to 20,000 hz.

It's interesting that our music isn't pleasing to humans in the higher ranges.


I'm sitting now windows open listening to spring birdsong and their notes, too, are mostly below 5000 Hz, with a typical range 3k-5k

Here are some instruments to compare, darker colors. Ignore the lighter color here (harmonics.)  from dak.com.   The chart is classic, so my Zentapper is probably the "violin" plus "bassoon" ranges on it.

On the chart, note range are dark colors (light color are harmonics.)   Classic, thus my Zentapper is probably "bassoon' plus "violin" ranges on here.

The contrabass site is a little out of date with bass guitar strings.
Manufactured strings are available for G#00 13Hz, Kalium Strings sell a .266 for up to a 40" scale.
Here's Kaliums' Skip with the 40" scale Quake bass he makes tuned G#00 C# F# B

He has a 60" scale instrument coming tuned down to D#00 10Hz.
Octave 4 Plus made a custom .412 string for use at B000 8Hz.

I think my chart was a little off.  I hate being wrong, but it seems like this is the correct tuning for Zentapper:

High notes (‘guitar’) 
 3   3    3   3    2   2       ZentapperFret
E2 A2 D3 G3 B3 E4      Note+octave
82 110 147 196 246 329       Freq in Hz
 
Low notes (‘bass’)  
 5   0   0    0    0   0       ZentapperFret
E1 E1 A1 D2 G2 C3     Note+octave
41  41 55  73  98  131      Freq in Hz


(the reason for that lowest string tuning on fret5 is that my tuner isn’t stable enough under 38hz, while e1 is a nice comfy 41.2hz)


Zentapper owners, please feel free to TELL ME HOW WRONG I am, I'd rather know now than have to unlearn chord patterns later, for sure. [smile]

I hope it's right this time, I even made little videos of tuning it for reference.
