The Expeditionary Force novels are solid and even better if you like audio books. We Are Legion (We Are Bob) and the follow up books by Dennis E Taylor, if you like project Hail Mary these have a similar tone. Hyperion is a classic, but is fantastic!

The El Capistan is nice, have played with the EQD though. Is there a specific delay sound you’re chasing or do need a Swiss army knife?

Source Audio Nemesis is pretty great and can do anything!

That is one rad axe, no better word for it!
