Organ doesn’t have enough Bass

This can result from a number of things. If the Leslie has a bad speaker that is a problem we see a lot. Placement in the room and room acoustics play a big part. You may want to try our tone booster see http://www.organguru.com/276-2/ or our super sub bass system that employs an 18" sub and separate amp. see http://www.organguru.com/super-sub-bass-booster/
