The Switch isn’t that expensive to make, the chip, memory, and storage are all budget af.

Justin guitar will give you the technique and knowledge, Rocksmith will give you the repetition and muscle memory. The Katana is dope, though blackstar makes a fun little practice amp too. For a practice one just try to find something used on FB marketplace or Reverb.

No amp is totally fine to start, and it’s better to practice unplugged and save up for the best amp you can buy for your needs.

My advice is to do the learning on Justin Guitar, and the fun practice on Rocksmith. If you can, find some local peeps that are also starting to learn and that will accelerate your learning big-time.

Basic first aid and CPR. Hopefully you never need it, but if you do the ability to recognize a medical situation and react accordingly can save lives.
