I have not started the online course yet. Just picked up my bass from the store. Had it set up by them. I’m sure I will learn how to do this down the road eventually.
My question for the members that have taken the course.
Do you recommend using a computer\laptop\chromebook, tablet or smartphone?
TIA for any input. 
Large tablet, laptop or even a full monitor. It’s SO much easier to read along on a large screen than trying to squint at a cell phone while simultaneously trying to play.
To be honest, I haven’t taken the course, but several others (both paid and free), and eventually a legit teacher will really help you further.
Pro’s of a teacher (my POV):
New insights in music (pop, rock, blues, metal, jazz, fusion, reggae, classic etc)
Live correction of mistakes, bad positioning/posture/grip, etc.
Social factor! You actually learn better from another human next to you.
Cons:
I do believe that Josh made an awesome online bass course, but nothing beats the real deal.
YMMV.
Plenty of people posting here about bad experiences with in person lessons from instructors.
No one ever posted here saying the course was anything but great.
The cost of the course would get you maybe five lessons from a teacher if you were lucky.
Respectfully, if you haven’t experienced how great and effective a learning experience the Beginner to Badass course actually is, you aren’t qualified to definitively compare it to any other learning method. Not slamming you. Just stating a fact.
Josh’s YouTube videos are fun and contain useful information, but they are not anywhere near the same as the pedagogically refined, thoughtful and thoroughly enjoyable curriculum he presents in B2B. These factors set B2B in a class by itself as a platform for beginners to learn technique, theory and proper application of bass playing.
Learning from a paid teacher in real time can be valuable for many. But having access to a world-class, methodical set of lessons and individual modules one can take at one’s own pace and reference forever — at a tiny fraction of the cost of an in-person teacher — is the best bass investment a beginner could ever make.
Again, no dis intended. I just say all this from the perspective of having experienced in-person teachers and also having gone through B2B as well as many other online courses.
I used a tablet and it was great in my experience. I play often with a headphone amp, headphones, and my tablet is connected to the headphone amp through Bluetooth, so I can watch and hear videos, and hear myself playing at the same time. And I keep the tablet in front of me at a good distance. I never felt the need to use my computer, because the tablet is so practical.
A smartphone would be too small. Anything else would be OK, except for a smartphone, mainly because of the screen size.
I used an iPad Pro to play the B2B course materials and experienced no issues. Anything with a large enough screen should work - as has been said previously, I suspect a phone screen would be too small to be able to properly read tabs and other on-screen notation.
I either played my bass through an amp, and played the lessons independently on the iPad Pro, or I connected everything through a headphone amp if I was being kind to my wife

I sit or stand in front of my computer that has 32” monitors up high. Nice and easy to see the notes at a glance vs trying to focus on a small screen. Especially on some of the more complicated songs with lots of string crossing and differing note patterns.
I use a Mac Studio and 27” monitor with a Focusrite 2i2 audio interface. I run the bass directly into the audio interface and wear headphones that are plugged into the headphone output on the audio interface.
I have an Xbox on my living room big screen with sound system. I used the built in web browser on the Xbox to do the course on my big screen.
Welcome to the low end! 
Congrats on getting your bass set up and ready to go.
To answer your question: I would definitely recommend using a computer or laptop.
While a tablet or phone can work in a pinch, a PC setup pays off big time – especially if you get yourself an audio interface (like a Focusrite Scarlett or similar). This allows you to plug your bass directly into the computer, so you can play along with the backing tracks in high quality and – most importantly – record your own playing. Hearing yourself back is the fastest way to improve.
And since you haven’t started the lessons yet, let me just add this to keep your motivation up:
There is no doubt that there are many ways to learn, and I’ve tried most of them – but nothing beats B2B.
Even if you are a fairly experienced bassist, I am 100% sure you will get something out of this course. But for anyone in their first three years of playing? It is simply the best, hands down.
The B2B course is so well-structured and thought-out that even a personal teacher would struggle to give you the same return on investment. Honestly, I would say the same even if the course cost 10 times more.
So, whether you are on week one or on your way to becoming a pro: Go through the course, use the forum, post covers in the 50 Song Challenge, get feedback, and become a Badass!
Good luck!
I have a handheld Windows PC (like a laptop but with a controller instead of a keyboard, like a Nintendo Switch or Steam deck, but Windows) . I started out using my tablet but I’ve switched to a setup where I can take my PC with me to my bass space.
At that space I have set up a portable monitor and a dock on a small end table. Bass goes to multi-effects unit, everything else goes into the dock. It’s nice because I can watch the lessons, but also hear my bass, record and dump into editing software if I want. I use Ultimate Remote to control the PC with my phone when I’m using it this way.
When I’m not using it at my bass I have it plugged in at a different dock at my desk where I play games.
However, my previous setup just used my tablet and it was fine I just wanted better editing software than what was available on Android, without having to carry files between the two.
I’ve used a teacher in the past and my experience is they are expensive and teach you very different things.
If you want to learn bass and gain a certain proficiency than Bass Buzz is the way to go. Cheap, easy, and you will learn so much. I cast to my big TV and get Josh on my home theater in all his glory.
The stuff I find invaluable from a teacher is some theory, and playing along with another musician, and asking questions. Also little tips and nuances. Thing is with teachers I get the most when I go into the lesson with a plan of what I want to go over that day. Otherwise you may get random stuff out of the teacher
I primarily did the course on my 17” laptop as that’s where my audio interface is setup and I’m usually playing with headphones so it was convenient. I have done some of the course on my older 10” iPad and it was still reasonably good. Since the website was redesigned, the screen size isn’t quite as important (it used to have a giant banner up the top and even on my laptop, the controls to navigate lessons didn’t fit).
Thank you everyone who took the time to share their setups!
I ended up using a large tablet. It fits on the music stand perfectly. I also ordered a USB-C to aux cable on Amazon to play it through the amp. (Had no idea this was possible) I can play with headphones or disturb the whole house now.
That’S what I do as well. It’s awesome.
