problem solved i replaced all the res around ic9 i think the person who built it didnt put 1% 200k but 5% so they where problematic
any why all is fine now
im just tryng to tune it with a guitar tuner
quite hard when i tune default oct now its fine but i switch to high one or low one it goes out of tune
is it a problem or i just have to fine tune the default oct and all the rest will be ok?
