From Daredevil:The Bootleg is an analog delay that utilizes the Princeton 2399 IC. 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 this apart from the rest is the Dirt section of the circuit, adding gain to the repeats. The decay will become brighter as it tails off…the opposite of most “tape style” delay units. Includes a Tap Tempo input for remote setting capability using a momentary switch. Details below. True Bypass, Hand Wired, runs on only an external 9V power source. 2.1mm center pin power supply, negative ground. Current draw is ~25 mA TAP TEMPO FUNCTIONALITY: Tap tempo will set the delay interval. Only 2 taps within range are required to set it. The delay interval will be averaged over the last 5 active (in range) taps. The max range of quarter note taps is 560ms, or ~108bpm. If the tap interval is larger than 560ms (
