The Bootleg is a digital delay that utilizes the Princeton 2399 IC processor. This was designed to give classic tones that sound similar to vintage tape machines, increasingly more lo-fi and dirty when driven at intense or longer settings. What sets these apart from the rest of the delay pedals on the market is the Dirt section of the circuit. You can dial in the amount of gain added to the repeats. When at minimal control setting, the gain is completely removed from the delay path. This 2nd Version of the Bootleg is without the tap tempo feature, the original Red V1 has the external input and digital tap capabilities. Delay Time at minimum setting is around 40ms.... max setting is roughly 400 ms. Powered by a 9V battery or a 9V adapter (not included in the package).
