Default New Martin and Anthem Issue

Hi all. Got an issue and was wondering if anyone has run across this before. I just received a new D-35e. I’m running it into a Touchmix 8 to a Bose L1 Model II. I was hearing a light static sound every so often from the Bose. It was very similar to the sound you hear when you unplug and forget to mute. Eventually I was able to reproduce it. Here’s a short video.

Has anyone seen or heard of anything like this before? Any solutions? Martin had no idea and suggested I call Baggs and I will tomorrow.

Static discharge?

Is it dry in that room?

No. Humidity is kept at 50%. No other acoustic I own does it or has ever done it.

I have the same issue with the harnesses on both my M80 pickups, though it could also be a broken cable to plug solder joint in your cable.

Try wrapping your cable around the end of your strap to take the free hanging weight of the cable off the plug. That’s what works for me.

I spoke with Baggs. They said that they have heard of this before and it happens with “certain finishes”. I found that kinda odd. It’s just a regular Martin, nothing special that I know of in the finish. Their solution is to separate the cables that run along the top to the control box. They are going to send me a couple of the self sticking wire clips. Not sure what to make of all this, but will certainly give it a try.

Interesting. I just dropped off a Martin D18 with my luthier to have a Baggs Anthem installed. He mentioned he had some problems with the 'preamp' before. I didn't think maybe this was related.

I have Anthems in (2) Collings OM's and both have been dead quiet and flawless for a couple years or more since I got them.

I take it all back: That’s a static discharge without a doubt, after watching the video.

A first time for everything, right?

Change your shirt?

In all seriousness it seems like a static electricity issue. Separating the cables may well fix it. But, clothes that go in the dryer will have static cling. Try a dryer sheet on your next load of laundry. Also, try a grounding strip, or touch metal to discharge before you play. Just because the house is humidified doesn't mean you wont have an abundance of static electricity.

I had this once from a brand new Anthem equipped Martin, it did it a couple of times and then never again...

Well I think I have it all sorted out now. Baggs recommendation of separating the wires seems to have done the trick. Either Baggs or I assume Martin had braided all the wires together to run across the top of the guitar to the controller at the sound hole. I guess they did this for aesthetics. So glad to have this fixed. No issues now and can play it plugged in. Gonna contact Martin and let them know. Hopefully they can find a better way to run the wires.

As former(10+ years) LR Baggs tech support, I can assure you that they do not perform factory installation for builders/manufacturers. I’m familiar with the static issues and can offer a bit of insight.

The static is most likely coming from the output lead. To confirm, unplug the output lead from the Anthem preamp/control unit and connect the now disconnected output harness to your amp, powered on. If the static appears, it’s being transferred into the output lead after the preamp/control unit.

Separating the wires should help but I’d also recommend using wire clips to try to both reroute the wire away from where your picking/strumming arm rubs on the body as well as to hold said wire away from the soundboard as well as you can.

As someone in the “know”, do you have any observations regarding the acoustical impact (degradation) of the Anthem system in an acoustic guitar? It’s a hotly debated topic with options from no acoustic change to drastic acoustic change. I’m curious what LR Baggs’ testing or position would be on this issue.

Thanks. That’s exactly what we did yesterday and it worked great last night. No issues at all.
