AC10 C1 odd buzz / harmonic

Postby SJB » Sat Jan 20, 2018 1:48 pm

My AC10 is producing either a distortion buzz or odd harmonic when playing the 1st and 2nd strings from the 11 fret upwards - when both strings are picked.
If one is sounding and the other picked the noise is present.
Individually the notes are clean.
Its been like this from New - though it was an issue with the G3 - but now I have a new guitar its the same with both guitars plugged directly into the amp.

Yesterday I replaced the EL84's - one failed with horrific microphony. For some time I was thinking that I would change the valves and this issue would resolve.
I have not changed the ECC83's

So if anyone else has an AC10 C1 - could you check if picking the 1st and 2nd strings 11th fret upwards - one after the other or together - you have this effect.

Thanks

Have you tried that guitar on a different amplifier?

It sounds to me like an issue with frets or the strings. I hope it's just the strings.

Thanks for the post Jim.
I have now tried my Ibanez guitar - same issue on all pickups. So we have the same issue on three guitars - so its the amp.

I made a dummy load - used headphones - and all is clear as a bell.

So it's down to microphony (did I spell that correctly) or the speaker. Or something loose.
I will check now with another AC10 (new one) which should be available for me to try on Thursday.

It's not an issue when playing live - but it is an issue recording.
