New booster circuit

[bluebunny]

Good news!   

Now this leads to my next question, is there somewhere I can learn all of this and not piece bits and pieces together from different websites and stuff?

Hang around here.  You'll learn loads.   

(Other suggestions will arrive here shortly...)

Like I still don't fully understand hfe and how to read the transistor data sheets. And if I move into a tremelo or delay I'm sure I would be lost.

I would recommend you start with opamps and learn how to use em, build some opamp-based circuits. Transistors are a lot more fiddly to learn about and use., I'd save them for next semester

P1 of C2 was connected to the emitter instead of the collector!

That's a very good chance to deal a bit with (misbiased) buffers (aka Common Collector amps aka Emitter followers..)

Now this leads to my next question, is there somewhere I can learn all of this and not piece bits and pieces together from different websites and stuff? Some free (or cheap) course or a good beginner website for pedal theory or a book you recommend.

Hmmm.... How serious are you? https://archive.org/details/TheArtOfElectronics-2ndEdition 
Edit: It seems that the 3rd edition is also available as a free download (although I wonder if the publisher knows that): https://www.pdfdrive.com/the-art-of-electronics-d33411099.html

LPB=Linear Power Buffer!
