Hi there.
Before I begin, I hope this post is appropriate. I guess it falls under "technical".
I'd like to share with you my bass preamp designs from a few years back. My life has changed direction in recent months and I have decided to call it time on my DIY bass preamp project. It has now been actively going for 3 years!
The following link has all of my research, designs, schematics, build notes, tests and conclusions. I'd really love it if anyone used my foundations for future development or inspiration. All I ask is you keep me updated on your progress.

The document on this page is part of my dissertation from 2012. It is a great resource for those looking to learn audio electronics, especially bassists.
I hope you enjoy reading it as much as I enjoyed writing it (cliche!)
