Its a killer man. There are 6 different clipping options, socket the last 2 and you can put whatever you want in as clipping diodes to really customise it to your tastes. IN position number 5 I put a 1n34a germanium diode and a 5mm red led. Really gets some crazy velcro fuzz going on. and thats just 1 position out of 6 clipping choices!
