KHDK Dark Blood

The KHDK Dark Bood Pedal is the latest coup from Metallica guitarist Kirk Hammet and David Karen. The circuit is a mixture of conventional transistor and MOSFET technology. The actual distortion section is preceded by an internal Treblebooster circuit. The sound control is also unusual: the "Doom" potentiometer, which is responsible for the bass content of the signal, is connected to the distortion section and determines the proportion of the low frequencies before the actual distortion stage. The integrated noise gate keeps the auxiliary noise in check even at extreme settings. The Dark Blood pedal is impressively represented on the current Metallica album "Hardwired... to Self-Destruct".
