Just out of curiosity how long did it take you to really began soloing? Also are there any really important scales that are a must know? I know the pentatonic scales pretty good, along with a couple others.
Well, I took me about a year before I started composing my own solo's for my band, and even then they were baised off a solo's I already knew. As for scales, I would have to say it all depends on what you play. For example, a blues player would use E, Eb, A and G scales a bit more then using like a C#. Just find the music you usually Jam in and then just find the scale which you can best manipulate to make sound like you want to.
Hope it helps!
