Thanks for this book since it served me very well as a beginner. The published edition gave me some tips for the Helix 4x sends and 4x returns. Additionally, I found some options for the LT with two additional Bass/Guitar inputs and the Helix with 5. I didn't find anything for the XLR Mic Preamp, but the Helix doesn't even have it. Instead, it includes the StageScape Mic Preamp. https://edubirdie.com/write-my-essay-for-me offers an analysis of the new edition, and even edubirdie's essay asserts that it has pretty useful instructions for line inputs of Helix and others. "The Big Book of Helix Tips and Tricks" provided me with a huge number of effects that I learned and what is better value for money. In a nutshell, I am satisfied and impressed by this masterpiece. The book taught me how easy to use, and how to make the touchscreen function - a modern and effective way to control the sound.
