Compact Duo Black Bass Keys

[tigervolt]

Hi All,

I recently acquired a compact duo ver. 1 for a good deal. Everything seems to work fine, but the black bass keys do not seem to work. The gray keys work on treble, but do not work when the bass is engaged. The first time I tested it out there seemed to be a really low volume coming out of the bass keys, but now, I don't hear anything.

I see others have had this problem and have mentioned it on this forum, but I seen no solutions other then check the contacts.

I've taken the organ halfway apart and have found not any bad contacts yet.

Has anyone that had this same problem found the solution? It sounds like it will be the same for most of us.

I should also mention, I don't think the percussion keys are working either. If they are, then it's hard to tell if they are doing anything.

I removed the whole percussion system (which I think is quite lame) and I still have the problem with the bass keys

I wonder if your reverb unit is working or not?
if not, your bass key problem would come from a component shared with the reverb system?
