Is the any real secrets to improvising? I mean, I'm pretty good at improvising just not great and I don't know how to get there.
Signatures are too mainstream

There is no real secret. The only way to get good at it is by just playing as much as you can.
Don't follow the trends. Do what feels right.

Doing it a lot really helps thats for sure, and not confinging yourself to a box is a good way to get really good improv solos to start to come out.
