I like when technical artists use "random notes" to transition between two regular riffs. I want to be able to recreate that when I'm messing around and soloing, preferably without memorizing odd scales or interesting little phrases to use.

Any tips on how to do that? Lots of tritones, perfect fourths, minor 2nds, and octaves, having lots of space between the notes seems to help....but I can't pin a specific method/system to it.
My gear:
Fender Showmaster FMT HH
BC Rich Avenge
1971 Gibson SG Pro
Vox Valvetronix VT100
1980 Martin D-18 (message me if you're in the market for one; my tiny fingers would prefer a Taylor)

Can you give an example? I was thinking about some Nirvana when I was reading your post, but I'm not sure if that's what you meant.
I believe your referring to tech death right? Chromatics, and augmented chords seem to work for me.
