Always liked my little old amp- But recently produces "crackling" sound in addition to any other noise being produced (by guitar). Suspected the instrument & cables- But substitutions ineffectual. Tightened bolts & screws... Etc. Funny though-> Input via the mp3 port is normal. Maybe a bit of mouldy cheese eaten before sleep.... Meaning that it might be time to try spraying electronics cleaning solution into the guitar input! Just guessing around.
Just wondering if anyone (been there/done that) can present some simple solution/answer....
