I have an electroacoustic folk guitar (Lâg 4 seasons) equipped with a Shadow preamp, and a Shadow nanoflex pickup.
During the past few days, I have been experiencing very annoying noises which, according to me, were due to a contact failure. While inspecting the guitar, and testing it all around, the issue seemed to be linked to the wire connecting the Nanoflex to the preamp.
To my surprise, the end of the connector can be taken to pieces by unscrewing it.
However, after I unscrewed it, and screwed it back again, the preamp is not receiving sound anymore. I really don't understand why this is happening, since I only unscrewed the end of it, and srewed it back.
Is it possible that unscrewing it broke the soldering inside ?
Note : I'm 99.9% sure the preamp is working properly, because if I plug it into a guitar amp, and I touch the pickup input with my finger, it buzzes.
