I'll be honest, at the time I was an apprentice still so I was broke but I wanted to gain experience and build my designs so I chose woods I could afford. Bloodwood and hickory are cheap and readily available so that's what I went with. Both guitars sound amazing. Crisp, clear, balanced, loud, and very responsive. I used 3 plys on my sides. Both inner and outer layers are hickory and the middle ply is either maple or mahogany, I forget what I had laying around for that one.
The back and sides do play a role in the overall tone for sure but will not make or break it as far as sound goe
