This is a junk item: the SansAmp "BASS DRIVER DI-J," a limited artist model featuring J (LUNA SEA)'s signature design. The exterior is quite clean. The entire top of the enclosure features the artist's carefully considered design, making it a visually striking preamp with a strong presence. The sound and specifications are the same as the original, as J himself felt it was perfect, making it a modern SansAmp with user-friendly mids (according to the manufacturer). The effect works, but there is ghost noise and the effect is weak, so it's best used for display or to replace the internal components with those from a new, current version 2! As a limited edition item, it is very difficult to obtain a clean unit. Although the price is slightly higher than the current model, I believe the satisfaction and value of owning the artist's carefully selected equipment is worth it. Please note that it is not expected to function as an effective effects pedal.
