The KFC Crystal Boost is a handmade clean boost pedal from Dr. No Effects, made in 2017 at the company's headquarters in Eindhoven, the Netherlands, in collaboration with the artist Koen Fu, who was working there as an artist in residence that year. Dr. No Effects describes it as a "high end clean boost pedal" with an in-house developed circuit, and it was sold as part of the KFC "Sauce Dispenser" series. Only 10 were made in total, and it carried a list price of € 235.001.
Controls and power
The pedal keeps things to the minimum a boost needs: a single Volume knob and an On/Off footswitch1. It runs on a 9V standard guitar effects power supply, the same kind most pedalboards already carry1.
The Crystal Skull
Unusually for a boost, each pedal has a Crystal Skull built inside the effect. Dr. No Effects states that the skull is activated by Koen Fu after purchase1.
Release and price
Only 10 KFC Crystal Boost pedals were made. Dr. No Effects also made a separate Crystal Boost, covered on its own page, which is a different product from this KFC limited edition.
The pedal carried a list price of € 235.001.
