From Roland:
"The GP-16 provides total digital processing, with the equivalent of 16 separate effects units, all invaluable for guitar players. It is a multí-efiects unit for which you can not only make settings for each effect individually, but can also arrange the order in which they are connected any way you please.

The GP-16 is equipped with 3 extremely high-speed DSP LSIs, newly developed for audio signal processing in the GP-16. The unit was designed with the focus on sound quality, with 24-bit internal processing. It adopts the 16-bit (64 times over-sampling) leading-edge MASH process tor the A/D section, and for D/A employs a 16- bit (4 times over-sampling) process.

Contained within the GP-16 are 16 digital effects units. Moreover, up to 12 effects can be used simultaneously.

Not only can any effect you wish to be turned on or off, but settings for choosing the sequence in which the effects are connected can be made and stored for each patch as well.

Since 2 guitar amplifier systems can be connected to the GP-16, you can store in memory, along with other settings, information on which guitar amplifier is to be used. Thus, eventhe guitar amps can be included in your sound creations."

In Excellent condition. Some wear from it's age but overall in great shape for it's age.
