I purchased a FBV Shortboard MKII today for my LD300 bass amp. Works splendid, except for 1 thing: I cant go back to manual mode, using the shortboard. The amp's manual says that i need to keep the active preset pressed until the amp goes into manual mode, but that doesnt happen. I also tried to tap it once, keep it pressed, but nothing works. What am i doing wrong? btw, Shortboard has the latest firmware loaded.
