Affordable Analog Delay You Have to Hear to Believe! High-quality analog delay just doesn't get more affordable than with the Visual Sound GarageTone Axle Grease Delay guitar effects pedal. In fact, the Axle Grease Delay pedal isn't just analog; it's an analog/digital hybrid circuit that combines the best of both worlds. The tone and the delay itself are 100% analog, whereas the circuitry that controls the effect benefits from digital accuracy. That means you get completely analog delay and all the insane space effects you want from the Axle Grease Delay's analog timing, with the consistency you'd expect from a digital pedal.
