Hi Sammy,

Welcome to Guitar Tricks!

Everyone has these problems in the beginning. Keep at it, keep making the minor adjustments in your angle and position to improve your tone.

I have a couple of tutorials here on GT that could be a really good fit for you:

ACOUSTIC CORE CONCEPTS: HOW TO MAKE FASTER CHORD CHANGES

"SPIDER LEGS" FINGER WARMUP EXERCISES

Let me know your thoughts - and best of luck!
