I would strongly recommend practicing solos to a metronome. Our ears get used to 'leaning' on the track when we play along to a song. It's analogous to hearing someone sing along to a song, then sing to a karaoke track or something without vocals.
If you can nail your parts to just a click or a drum machine, re-adding the rest of the instrumentation will be icing on the cake. It takes a lot of work, but it will develop your control and confidence and command of what you play.
I'll even go so far as to master a solo and have the a click play only beats 2&4, or the upbeats or have a click that "drops out" and returns at certain intervals.
That is seriously good advice. Filling in the rhythm and chords in your mind is very good practice. In addition to confidence, it forces you to really understand what you're playing.
I like having a personality, not someone else's.
I get that. Completely. I wish I had the technique to mimic other players exactly....but to be honest, my combination of vibrato, timing nuances, and technique 'cheats' always means that I sound like me. It's taken a long, long time--but I'm actually pretty happy with that.
