I recently purchased a Condenser microphone from Blue, the Blue Spark microphone. I used it on a guitar once for live performance because the pickup on that mic is amazing, and it worked phenominally. I would consider it but do be advised that it is super sensitive and would pick up anything that happens in your room while recording, a piece of dust hitting the floor lol. I would recommend it 100% although I have yet to try and record a guitar with it, but I just know it would be fantastic. Look it up on YouTube!
