So been jamming with some mates for a while now, not sure on the genre but if I had to classify it, it would sway towards a fairly melodic sounding deathcore /prog metal sound.

As lead, i've been messing around with minor scales and just some patterns you learn here and there, but focusing on originality, I've decided its essential to start learning some theory...
I'm looking for some texts that explain all the modes/scales and their fingering patterns (notation or tab) for guitar

Where's the best place to get started?
If someone could point me in the right direction, perhaps a text or an e book or even a youtube channel, I'd like to learn the modes in our jamming "key"
We play in Drop B (BF#BEG#C#) So I'm assuming i'll be learning initially in C# Standard..

Would appreciate any help as its been an underlying problem in my lead playing for a while now.
