It seems that every time I try to improvise, I play like the same thing. Not the same notes, just like phrases, and bends. Every pattern I try is always the same length as my previous one, any help on getting new ideas?
Try listening to a new style of music and get inspiration from there. (If you are used to punk, get into some jazz, or something like that.)
