Voodoo Bass

"Sonically, the Voodoo-Bass is similar to that original Voodoo-1 pedal (as in Jimi´s "Voodoo Chile"), giving anything from a slight natural crunch to a smooth powerful distortion. At maximum gain it makes a medium-sized combo sound like something about four times bigger, but without the over-compressed wall of noice associated with most stomp boxes. In fact it allows for very dynamic playing; chug a chord from soft-and-damped to loud-and-ringing and the pedal goes with you - from quiet and relatively clean to over-the-edge grunge. Alternatively, simply control your overall volume ( and hence amount of distortion ) from your guitar´s volume knob. The Voodoo-Bass is designed to give a single coil pickup a gutsier tone, more like that of a classic humbucker. It definitely gets into same ball park... the low middle stays thick and constant no matter how the tone is set, and it´s this region that has the humbucker character - a really handy approximation for someone wanting a change of sound at the press of a button." " The Voodoo-Bass sounds refreshingly unboxy, and with most types of amps it does the job really professionally."

Making Music Dec / -96

"The voodoo-Bass is an analogue fuzz box that adds thickness to any bass-and at higher gain settings, the Voodoo-Bass simulates the tube-like sag of a full-blast vintage amp."
