The 2 courses are aimed quite differently.
The “How to Digital DJ Fast” course focuses solely on DJing techniques and some fast tracking through song collecting and music organisation. It will give you all the basics you need to DJ and you are ready to spin and do basic mixing, manually beatmatch and get on the road to becoming a DJ.
However it will in no way make you pro over night.
Now while the Masterclass also include those topics it does go a lot more in depth and expands also on other topics on the way to make you a pro level DJ. (Watch the presentation for all the info)
So in the end you get what you pay for. Of course I say the Masterclass is totally worth it, but then I am already a DJ with 20+ years of experience. I know what I went through and I would have literally sold my soul for a course like this when I started out hehe.
Hope that helps you.
