This is a listing for a Fryer Mayday. It has only been used indoors. Operation has been confirmed. Please understand that this is a used item. There is also a letter with setup examples from ks guitarworks. The Fryer Guitars Mayday (Mayday Overdrive/Distortion) is an overdrive, a distortion, and a preamp that can create vintage sounds. The Mayday is a perfect match for the Treble Booster Special. By connecting it after the treble booster, it is designed to produce the sound of a full-up AC30 at a lower volume, making it suitable for home practice and rehearsals to achieve full-volume harmonics at low volumes. It can also be used with treble boosters and distortion pedals from other companies. Furthermore, turning on the "D" (Distortion) switch emulates the sound of the legendary "Dicky" amp. The combination of the Treble Booster Special and the Mayday can reproduce the Brian May sound from live performances and records. ■ Power is only supplied by a 9V AC adapter (center negative), and battery operation is not possible.
