The ESP M1 Custom is part of the ESP Mirage Series and was introduced in 1987. It has a Dinky body, neck-through body construction, double locking ESP tremolo, one high output active humbucker and a coiltap. It has a Jackson-like headstock over which ESP was sued and caused them to change the headstock in later ESP guitars. The lower horn of the guitar is scooped and has a block inlay on the twelfth fret.
