" Hi Jerzy, thank you so much for the great course and resources. I've already planned out 3 very different basses and I can\'t wait to start building.  With these resources
and the training video its so simple to plan out and line up the separate templates and produce high quality build plans.
Thanks Again, I'd recommend this toolkit to anyone looking to design their own instrument

" I'm a bass luthier located in Brisbane, Australia. So far I'm very happy with the toolkit, I already happened to work with Rhino3D and own a small homemade CNC that I use mainly for building my templates.

Jerzy, your videos have shown me quite a few tips with working with Rhino which will help me produce my designs/templates a lot faster. I especially like the whole system the way you design the instruments. I've started modelling some of the parts missing in the toolkit that I use the most, i.e. my headstock designs and a few other parts. This is going to be a major help, thanks very much for the toolkit!....

" BGDT™ is a great resource for bass designers and builders at any level. With some CAD knowledge, but Without any previous experience in instrument design, I could assemble my first plan in less than an hour. Experienced builders will benefit from BGDT parts library, which is a real time-saver. Overall, I would highly reccomend BGDT to any bass luthier, designer or enthusiast....

Design with CAD software or classic drawing table

drawing-table It doesn´t matter if you love or hate computers. With BGDT™ you can work using CAD software or classic drawing table as well.

monitorAll content is delivered in 3 different formats so you can choose the one that best suits your particular needs.


3 different formats

Bass Guitar Designer´s Toolkit™ is very flexible and allows you to work with


3dm-icon  .3dm format:

dxf-icon  .dxf format:

if you work with any CAD software but it´s not Rhinoceros, then you should use this format.

pdf icon  .pdf format:

this format is for all of you who prefer designing your instrument on paper. Just print it on standard or onion paper and use it on your design directly. Please note that that you will be unable to open it with CAD software.

bass-scale-planBass Scales

You don´t need to calculate manually bass scale for your bass.
You don´t need even to use a scale calculator, as those are available out there on the web. With BGDT™ they are unnecessary and absolutely useless.

You will get  all common scales  already calculated like 30", 32", 33" 34", 35" and 36" scale and all of them are already made for you!. 
You can create any intermediate scales if you want as well.

Would you like to design a bass guitar with 33,5" or 34,25" scale?  Well, that´s easy. You will learn with BGDT™ how to do it (for more info see 6. ...and More Stuff below).

nut-plan48 Nut Shapes

BGDT™ Comes with a bunch of pre-designed nuts so you do not need to make these nut calculations if you don´t want too.
You will find nuts for a variety of widths.
Additionally, I have included front nut shapes that you can use for making your own nuts when you start building your bass guitar.

bass-body-plan100 Body Shapes

I know you are looking for some cool shapes for you bass guitar project.
For this reason I have included not only a variety of different body styles for standard 24-fret layout but also versions for 28 and 36 fret necks. Some bodies ale also available in 22-fret version. 
Please note that all body shapes inside of DXF and 3DM folders are 100% editable, so you can stylise them to achieve unique and outstanding bass guitar designs.

You can also edit these shapes so other fret version different from 24, 28 and 36 are also possible.

headstock52 Headstock Shapes

Inside of BGDT™ you will find also many different headstocks with different shapes and different tuners layouts like 2L+2R, 4L, 3L+2R, 2R+3L and so on.

In this case I also wanted to make your life as easy as possible so I have placed tuners already on each 4, 5, 6 and 7 string headstock version!

All headstock inside of DXF and 3DM folders are 100% editable, so you can adjust them to match your particular needs exactly the same way as with body shapes.

Electronic cavities are designed already for each body shape.

B-calc-logoBass Guitar Designer´s ToolKit™ also include very useful and easy-to-use B-Calc™ software which will speed up your next bass guitar design project.

If you have ever had to design a new nut, I´m sure you know already what I am talking about.
Sincerely it can be a pain in the ***  :-)))) pantalla-b-calc

B-Calc™ help you calculate spacing between strings, depending on the number of strings, string gauges and overall nut width.


Calculate nut spacings on instruments with up to 7 strings

This awesome software calculates nuts from 4 up to 7 strings. To make things even easier for you, reference tables with standard tunings are included in each screen

100% Flexible

All parameters are adjustable like:
    yes-mid  nut total width
    yes-mid  number of strings
    yes-mid  distance from the bottom nut edge to first string
    yes-mid  distance from the upper nut edge to the last string
    yes-mid  gauge of each string ( see more info below)


Choose string gauges for each string independently

b-calc-detalle-2You are not limited to standard string gauges.
Let say you want to use medium gauge strings, but since you prefer lighter bottom you would like to change just one or few strings gauge outside of the norm.

Well that´s easy, just type your desired string gauge inside the string gauge box.

Everything will update accordingly to your chosen dimensions.

Work with Imperial (inches) or Metric (millimeters) units systems!

b-calc-detalle-1It doesn´t matter if you work with millimeters or inches. B-Calc™ is compatible with both systems. Switch from metric to imperial Tab in a moment. 

If you are Professional bass builder and you have clients overseas, you can calculate these dimensions and report them to your client in just in few seconds.

Mac OsX and Windows versions are included!

windowsappleB-Calc™ comes in both native Apple OsX and Microsoft Windows versions. You can use both without any limit on as many computers as you want!

Is B-Calc™ for bass guitar only?

No, no, no. You can use B-Calc™ for any nut calculations. This software was originally designed for bass guitar, however you can calculate following musical instruments nuts as well:

Now, CAD software is what you need to be able to make your bass guitar designs. Unless you prefer working on a classic drawing table you will need very good Pro CAD software to work fast and efficiently. 

I have to share a story with you.  The idea of Bass Guitar Designer´s Toolkit™ came to me mostly two years ago!!!  I had that crazy idea on THE SYSTEM for bass guitar design. I got all components to make it work, but got stuck on CAD software.

You will see, there is a lot of absolutely extraordinary software which is perfect for designing instruments but there is one problem, the price!

Most of them cost  thousands and thousands of dollars. This was the biggest handicap I had.  Think about it!!! How I can offer you such a awesome system as BGDT™ if you have to spend an additional, let´s say, $1000 or $2000 or even $5000?! That´s crazy!

So I spend a lot of time researching, testing researching and testing again, until I did find this little gem!  This CAD software is not only perfect for designing instruments but it also will not cost you even one penny! 

Finally I found the last piece of puzzle, so the BGDT™ could come into reality.

Inside of Bass Guitar Designer´s Toolkit™ you will find instructions how to get this Top Class CAD software absolutely free of charge and of course 100% legally


Important Note for Mac Users:

appleThis CAD software runs on PC (XP, Vista etc...) you can use it on your Mac but you will need to use Bootcamp which you already have in your Mac OsX or any additional virtualization package like MVware Fusion or Parallels.

Additionally you will need to install Windows on it. I’m still searching for perfect CAD software for Mac unfortunately I have not found it yet.
If I find that perfect CAD software for Mac you will receive that news from me!

Until then use Bootcamp or MVware Fusion or Parallels and start enjoying BGDT™ and bass guitar design today!





I want to give you even more value with BGDT™ System so I decided to include some additional material which will be available shortly in your BGDT™ Content Page.

Here is just a short list of upcoming extra material:

       yes-mid Video Tutorial on designing neck pocketing for bolt-on instruments
       yes-mid Video Tutorial on designing a hollow/chambered cavity for bass guitar body
       yes-mid Additional Bass Guitar Parts Library
