Once you know a few pentatonic lines and want to play say some blues,you can embellish and make note transitions with simple vibrato and bending technique. You do not need pedals or a great amp to create an illusion that you have a big one.Dig hard and extract melodies from the five notes and all the spaces in between. Bending strings dissolves the frets so its a cool way to emulate the slide ( I have lost and broken all mine). So here is a short clip on playing the blues with traditional cliches and some nuance. Hope you like it and cop some sidey lines :D
