Can anyone help to give any clues about identifying this part? It is from a Chinese guitar pedal and appears to be at the beginning of the input chain, so I would suspect perhaps some kind of op amp, but might be wrong. None of the markings seem to match any prefixes in the SMT codebook, etc. but I just wondered if it might happen to mean anything to someone with more experience.
