PEARL F-604 Analog Delay Flanger

Very rare Pearl F-604 Flanger Analog Delay Effect in good condition.100% original and full working order. Quoted from Nicholas Kula at Tone Report ;Wait, what? Yes, you read that correctly. Flanger. Analog Delay. Effect. All these words add up to the strangest Pearl offering by far. This “effect” doesn’t really know what it wants to be, and is likely the main reason that the Pearl line nosedived into obscurity. Four knobs make up the control panel, and even the order is a jumbled mess: Delay Time, Depth, Repeat and “Flang Rate” read from left to right across the surface. What on earth is going on here?Some circuit jockeys have speculated that the Pearl FADE ( Flanger Analog Delay Effect ) is simply a copy of the MXR M117 Flanger from around the same time period, even sporting the same bucket-brigade chip (the Reticon SAD1024). However, the FADE actually offers a delay control that tops out at around 300 milliseconds. Combine that with a unique flanger effect, and the FADE is one of the most bizarre slapback machines ever built. Some might wonder if Pearl was going for an actual tape delay sound ages before anyone else; after all, flanging originally began on a tape unit as well as delay.
