Crazy Tube Circuits Killer VKiller V was inspired by some very cool and unique amplifiers born in California, USA in the 50s and 60s, with a very distinct, true pitch shifting vibrato circuit. With every detail in mind we copied the behavior, sound and feel of the preamp, phase inverter, power amp and the compression sag of tube rectification found in these designs. Applying JFET technology and an internal voltage multiplier for high headroom and the ultimate tube like tone we
