Hi, guys! There's my second thread here. I have a few other problems with my MM BFR JP.

First, when I'm in "mono jack/magnetic signal mode" I hearing noise and hum when I move tremolo bar or other parts of my guitar like if there is bad grounding. Btw, when I switching to the piezo signal in that "mono jack mode" noise/hum immediately goes away!
Second, if I play with 2 cables in stereo mode/magnetic + piezo signal, when I switching to magnetic signal - a big part of noise goes away (but there is still a little bit) and also my highs goes away like If i turned my tone knob down a little bit.
Third, when I'm in "stereo mode" piezo signal is much louder than in similar situation with piezo signal but in mono jack mode.
Is that NORMAL??? :confused: Do you know, guys, how to solve this problem? I contacted CS and they told me they need to see guitar to take care of it, but I live outside of the US and there's is no way to send it directly to MM CS. :(
Thanks.
 
I'm afraid it's hard to diagnose anything from the description. If you've ruled everything else out- different cables, amp, etc, and you're sure it's the guitar, then you need to have somebody qualified take a look. Perhaps a local dealer?

OK, I'll give 'em a try, but if there's is nobody to check that, I'll need to send it to Sates to MM CS?
 
I have the same problem with my shilouette. When use mono its normal, but when i only put on magnetic jack, the high signal is cut and there's short mute when changing between pickups
 
Did you ever figure out your problem?

I'm sorry I don't mean to thread crash. I wasn't able to start my own thread for some reason. I just picked up a used 2013' Black Ernie Ball MusicMan JP6 BFR. I noticed when using the mono plug from the guitar and I'm in Piezo mode(top switch all of the way up). Then connected to amplitube 3 on my computer. The "D" and the "B" strings sound almost dead. 1/2 the volume of the other 4 strings.

When nothing is connected and the guitar is unplugged all 6 strings sound the same. And when I turn the piezo system off. The top switch all the way down, and the guitar output is from the stereo(magnetic) port all 6 strings are the same volume there too.

Any ideas?
 
I guess the forum is dead, nobody really gave solution other than 'take it to dealer'
 
The forum is most certainly not dead... :)

But I'll tell you what the mods and employees of EBMM will tell you--- call customer service. That's what they're there for. Even Sterling Ball (you know, the owner of the company AND this forum) says clearly in the rules of the forum--- please call customer service BEFORE posting issues with your instrument here. :)

Tommy- It sounds like you might have a couple of dead piezo saddles, but it is very tough to diagnose without having the guitar in front of us. Sooooooooooo..... Call customer service. :)
 
How can anyone diagnose your problem over the Internet?

Call MM customer support and they can help sort you out, or send you to someone that can.
