This has come up a few times. If you have specific questions or want to request additional documentation (I am not sure there is any other than what ships with the PS 700), you can ask at generalproductinfo@seymourduncan.com, or call during normal business hours Pacific Time @ 805-964-9610 ext 1092. if you have general questions, we might be able to help here, as a few people here use the PowerStage 700.
