Thx Surfergirl…yeah the HumX and a ground lift made it worse? Strange. I’m trying an audio isolator next, which is more expensive than the humX! Yikes! We shall see.

Yeah, I don’t expect the cables to do anything but thought I’d try…I also ordered an audio isolator…ha ha, digging in the bin of ideas here. it is the same reduction in noise (minimal) when I touch any grounded component, which I understand to be normal but the presence of the initial noise is just too loud. I have actually used an EQ to isolate the noise, I forget the exact frequency (not home at the moment) but that’s a bandaid not a cure. I love the new pickups idea!! Scott, yeah I hear you about the cables. The pickups are tapped. I don’t believe the bridge ground is unconnected, if it was I think touching the bridge would have no effect on the sound. Turning the volume on the guitar down removes the noise, oddly enough with the volume all the way up the noise is reduced but not eliminated, moving the guitar has no effect, I tested with everything in the house off via the main panel, just left on one circuit, no change, so it’s not lights computer etc. I tried a ground lift and humX eliminator, both made the sound WORSE!? Thank you folks, you’re so generous with your time and advice!

Thank you Scott, for the response… you mean you replaced the guitar cable? I tried a few cables I have but no change. I did order some balanced cables to try…I’m scrambling here so I’m trying anything.

Thank you for your response. I understand it’s difficult to diagnose. I have tested the outlets, appropriately grounded. I had the wiring reworked by a local shop with a good reputation, can’t say much more for the internal but the tech says it’s good and the buzz is normal. I haven’t tried the guitar at another location other than the guitar shop, seems to be the same… im not sure about the covers being grounded, but I don’t think so. I believe just a single ground off the bridge to the jack, pots and switches grounded to bridge if I remember the wiring diagram correctly. Thanks Again!

Good Evening Everyone, I have a Comins GCS-1 and a Fender Blues Junior (pictured). I record with it into an iMac, either direct through a Scarlet i88 or a Zoom R16 or with the amp & microphone Shure 57. The guitar has a terrible buzz, (audio attached). It is not the amp as it is apparent when I run the guitar directly into the iMac as well. I’ve tried all the usual suspects…it sounds like a 60 cycle ground loop… when I touch the strings, jack etc it is a little better … I know, I know this is “normal” but it isn’t, it can’t be…it’s a low drone beneath everything I record it’s terrible. I am running everything through the same house circuit…I even turned everything off in the house via the breaker panel except the guitar and amp, still BUZZ. I am using a surge protector with RMI filtering. I tried a HumX eliminator…it only made it worse! It’s a semi hollow so shielding is out. I recently had the guitar rewired, it was there before and still is. Guitar tech says it’s normal but it just can’t be…it’s a terrible noise. Please help, I play mostly clean, so it is very noticeable in recordings. Thank you! Project Guitar Buzz.m4a
