Hello,

What kind of cable John Petrucci did use on those JP6 guitars, because JP6 seems to have two jacks i`m little bit confused. What kind of guitar cable i need to get all functions out of JP6, and use it way like John Petrucci uses? And Piezo version JP6, what kind of cable i need to use all functions? Regular mono cable you can not get Piezo, and magnets same time or one at time?

Two mono cables will give you one magnetic and one piezo signal, controlled by the upper horn selector. Stereo cable in the stereo output will give you a splittable signal with a Y hardware you need to add.
Mono cable into mono output will merge all signals.

Wonderful info does that mean i could get Piezo and Magnets just using mono cable on that stereo output jack, or do i need to use stereo cable to get those both working on that jack? And also can you recommended some cable which works, i mean if i need stereo cable does both ends need to be stereo or only one stereo end and one mono end?

I always use a stereo Y cable in the stereo output.

I run the mag output to the Guitar-In in the Helix, and run the Piezo to the FX return. Then I program my patches to use the desired input (or a mix of both) e.g. for cleans I use mainly piezo plus a little mags, and for metal I use the mag input only. This means I can switch sounds with my feet without ever having to touch the switches on the guitar. Magic!

What kind of stereo Y cable you are using any link need to use both stereo ends or could one be mono and one stereo ends? And can you use magnets and piezo just whit one stereo cable, or do you really need some kind of splitter box to feed stere output on JP to that and that box would split two mono outs?

The stereo cable (known as "TRS") has 3 connectors- Tip, Ring, and Sleeve (TRS). It's basically like 2 cables that share a ground (tip/sleeve and ring/sleeve).

So the Y cable gives you just this- a TRS ("stereo") connector at one end, and 2 x mono cables at the other end, one connected to TS and one connected to RS of the TRS cable.

The JP (and other MM guitars with a piezo) give you two options- you can either have both magnetic and piezo signals combined on a single mono cable, or you can use a TRS cable and have the magnetic and piezo pickups on separate connectors (T and R), and have them share a ground (S).

If you're using separate amps for magnetic and piezo pickups, using a TRS cable makes a lot of sense. You can use either a TRS cable into a "breakout box", which will split the TRS signal into TS and RS for you (where you can plug 2 mono cables in to), or you can use a Y cable (like above) and do it that way.

If you have a single amp, then a mono cable (with magnetic and piezo signals combined) could work fine. For example, it's popular to mix the piezo in with a clean tone for a fuller clean sound.

I guess it all depends how you want to use the piezo, and what your amp setup is like.

Hey, amazing info again thanks for all that, my question is now if i use just one mono amp. Can i get via mono cable piezo and magnets on that stereo output jack, or do i need to use there that stereo cable? Plan is not using two amps just way like Petrucci himself did use, clean tones magnets and piezo together. What kind of cable i need that kind of wiring?

For a single amp, where both signals go to the front of the amp, use a mono cable like you would with any other guitar. Then use the selector switch on the guitar to select between magnetic or piezo sounds.

Do you mean i can really use regular mono cable to get both piezo and magnets, i was thinking i need that stereo cable TRS for that kind of thing? And do you know did Petrucci uses or uses these days on JP6:s, just one mono cable i would like to get that piezo and magnets both blended middle position like he did use can i do that whit just one mono cable?

I have no idea how Petrucci uses it, but yes to your question.

With a TRS cable, each signal is on its own connector (tip or ring). With a mono ("TS") table, the two signals are mixed together through the preamp. You have one cable where both signals are combined.

Thanks again for reply i was so confused, that if i need to get TRS stereo cable for get that piezo. I just plugged in the Stereo output whit mono cable, and i get both magnets and piezo and i can toggle them whit that upper switch? And no need to use TRS stereo cable on one mono amp, i get piezo and magnets just mono cable all correct?

Correct!

The website also has diagrams for this stuff. The JP6 isn't there, but here's something similar. Scroll down and click "Controls":

The advantage of the setup I use is that you don’t need to touch the switch on the guitar. You leave it in the middle position so both mag and piezo are active at all times. The foot switches on the helix determine which signal is processed. This works on any guitar that has a stereo output.

That sounds so nice cool

For a mono amp you plug a mono cable in the mono out... It will merge piezo and magnetic
