Casio LK-100 with no Lows.

Casio LK-100 with no Lows. As you go down the keyboard,  notes get weaker and weaker from headphone jack or speakers.   Coming from the headphone jack into a mixer, cranking up the lows, it sounds okay. Bad coupling capacitor? Could use a schematic.   Anyone to do any mods on these keyboards?

Haven't done any real mods to this keyboard, but I have opened it up for cleaning. Make sure all the screws in the back are screwed in all the way, I had a problem with mine where the volume slider was very crackly, and all it took was tightening the screws. Casio wired the sliders up very strangely, as the volume slider needs to be on the contacts or else it will not make any sound what so ever.
