Over two days, I read the manual, the whole thing, start to finish. My wife held her tongue and didn't say 'you should spend less time reading and more time actually playing your guitar'.

Cool things I discovered BIAB could do:

Trade solos with a BIAB generated soloist (trading 8's, eg.)
Generate BIAB solos, fine tune them, and learn them
Import audio, select a section and play it at half speed (learning tool!)
Import VIDEO, and play it at half speed! (watch somebody play a lick at half speed!)

In case you didn't know about those features...

User manuals as pdf files are great for using Ctrl + F to quickly search and find when you know the exact term you're looking for. But, in my humble opinion, a printed manual is worth its weight in gold.

You can read a printed manual as long as there is enough light to see the page. You can fold page corners, use post-it notes to mark a location or add a note and mangle as needed.

I ordered a hard copy of the 2019 Band-in-a-Box manual yesterday. PG Music was out-of-stock for awhile but stock has been replenished.

It's very reasonably priced at $10 US plus shipping.
