Hello ,

I would really be happy somebody could help us, we built nava 1.02 everything working , but the bassdrum is not really there it sounds very thin and tune is not working. Would be nice somebody could bring us next to the reason.

Thanks in advance

Hi,

I have just finished my Nava and I run into the same problem... :(

The kick is thin and I hear only a tick but no decay at all.

I have the last Nava batch with Extra9 mod in place.

Do you find a solution ?

Cheers :)

I have checked all resistors, seems to be OK !

Tried to swap the 5218 but no change.

Checked all extra9 wires, seems to be OK.

Checked the output of the vco, there is a signal.

Still investigating :(

I have also posted on Muff wiggler with some pictures of scoped signals here https://www.muffwiggler.com/forum/viewt ... 6#p3472846

EDIT : Everything is working now, it was just D12 soldered in the wrong way !
