Hey all,

So I just received my very first EBMM guitar, a JP15 on this past Saturday. Love it so far, but I've found something I'm puzzled by.

I was reading up on my routing options within my Axe FX III, and I got excited because I can run two mono/TS cables from the JP15's separate outs from the diagram sheet they included to the different inputs of the AFX3 (specifically In 1 and In 2 Left, routed to Out 1 L and Out 3 L for mono, no XLRs at the moment). This, in theory, allows me to create two separate signal paths, one for mag and one for piezo without crossing the streams.

The issue I am running into is when two separate TS cables are connected, the piezo pickup signal is the only one seemingly passing audio (in position 6 and 5). Single TS in the mono jack works, and a TRS in the stereo jack works. It's only with two TS cables connected where the piezo is the only signal recognized by the AFX3.

I've done the necessary routing within the AFX3, so I'm almost certain it's within the guitar itself. New battery and different cables tested too.

Any idea what could be causing this? I just got the guitar and love it, and I'd hate to have to stick to the Mono jack or have to buy a TRS to Dual TS if I don't have to.

It might be, that you have to connect only a TRS cable to the stereo to have both outputs separately.

Not sure, why it acts like that, though. At least, I would have assumed mag only on stereo with TS

According to the diagrams on the site, the JP15 should give you separate outputs with two mono cables, so that is odd. I would drop customer service a line and ask their advice.

That said, using a TRS cable does seem like it would be easier to use. Make/buy a breakout box so you can plug a TRS cable into it and have it split off into two TS cables. Then you only have to deal with one cable from your guitar.
