Thanks for the replies! Sadly, I sold many electric lute so I could buy the parts for this project. It looks like I have some research to do on how to reduce the drive and some research on heatsinking. I would have guessed that more resistors in series connected to the input would have lowered...

1. TLDR warning (don't bother unless you're bored)
2. I've built my circuit as a new cook would follow a recipe. I don't always know why I'm doing what I'm doing, but the recipe (schematic) says so, so......
About a year ago I build a headphone amp for my guitar as directed...
