Infected Mushroom incorporate acoustic and heavy electric guitar into some of their songs. They're considered psytrance soo...
Good examples are Becoming Insane and Poquito Mas for acoustic and a lot of their songs have electric so I'm not going to bother to name any off the top of my head in case I'm wrong :p I think End of the Road deserves a mention cause I just love the bluesy riff :p
End of the Road:
I ment like songs like this one https://www.youtube.com/watch?v=_mxR0jH4BEI&list=FLO2mBwsIiwXpJHz0pM7pS8Q
