ive come to ses some of these too. but, my fbv wraps around not sure why yours doesnt? yes it comes with limited documentation but a quick search on here or on google reveals what all the effects and presets are for. then finally the drum loops cant be spend up because they are actual recordings of an actual drummer. hope this shines some light on a few of your bads if i can find the pdf for the effecrs ill post it but i printed it out when i found abd im not sure i saved it.
