A bit of an odd one but just wondered if anyone has any thoughts. The attenuverter linked to the frequency input on my Rings no longer seems to be channeling the 1/12th of a volt for fine tuning with noting patched in. The attenuverter still operates exactly as expected when a CV is input, just not with nothing patched in. Would that suggest that the switching on the jack has mechanically failed or something? It’s from the first batch that came out last December.
