JP6 w/ piezo question

[Platypus]

Hey there, just got JP6 in after a long wait!

From what I've read, if you have both 3 way toggles in the bridge position and you're plugged into the mono/piezo jack, this is theoretically just the bridge magnetic pickup correct? For some reason when I do this my tone is much more focused/brighter than using the bridge pickup alone in the stereo/magnetic jack.

Any thoughts on this?

 

[greenwizard]

Theoretically you are correct. When I A/B the two options you've described I don't really hear much of a difference though. Are you hearing a very noticeable difference?

 

[Platypus]

It's not a blow-away difference but you can definitely hear it.

Nice JP! It took me a couple reads to figure out what you meant, and I would have to say my JP has no noticeable difference in this way. Of course I'm away from my guitar now, but I've never heard a difference. Is your battery doing ok?

It's brand new so I imagine it is, I can check that though.

It sounds 'better' in the mono with both 3ways on bridge so I can't complain, just curious what the deal was

Sweet set up!
If you think of this as a problem, rather than just a cool piece of personality, then you might want to give CS a call.
They're fun to talk to anyway.

 

[Platypus]

Thanks, I'm curious if anyone else hears it or if I'm a mutant

I think it sounds a tad brighter overall, I can record some clips of it when I get a chance

 

[the24thfret]

If you could A/B it easily on a recording, that'd be great.

I think it's your super Platypus hearing...

I could be wrong about this, but I think you've mischaracterized the outputs and the switches on the JP. There is only one toggle with a bridge position and thats the normal magnetic pickup selector. The toggle on the top horn only selects magnetic/ magnetic & piezo/ piezo. As for the outputs, the output nearest the strap button is for the piezo, while the other is for magnetic or can be used with a TRS cable to output both magnetic and piezo signals.

If I plug into the piezo output with the top toggle in the magnetic position, I get no output at all. If switch to the middle position for both magnetic and piezo I get piezo and no magnetic. Switching the toggle to the top position still get piezo only with no difference that I've noticed in tone.

Likewise plugging into the magnetic output with a non stereo cable I only get magnetic output regardless of the position of the top toggle.

I typically use my JP with a TRS cable into the magnetic output going into an EBMM splitter box that I got from Pete DuBaldo. From there I go to my normal rig and my acoustic amp.

That sounds like the cleanest cable solution. I've not heard of that option. Does the splitter have a ground lift to keep the two amps from creating a ground loop?

 

[PeteDuBaldo]

There is no switchable ground lift on the splitter box, lots of people run a DI with a lift on the piezo size.

There should not be a difference in volume/output when using the magnetic pickups via one jack or the other.

Hey Patypus,
Welcome, and nice guitar.

You're from the Boogie Board aren't you? Stick around, this is a pretty cool hang.

Just thinking out loud here. On the blended output, the mags are going to go through a unity gain preamp and the signal becomes active. On the dedicated out, you're getting a passive magnetic signal. It's unlikely you'd hear a difference tonally between the two, though that could be the case.

But ... if you're using the active out in a long cable run, the difference you hear may just be the cable. You generally lose a bit of high end with a long cable (due to capacitance). However this doesn't happen with an active signal. If you use a low-capacitance cable or a really short one, then likely you won't notice any difference at all between the two.

Just my two cents.

 

[Jimmyb]

Yeah, that seems pretty logical Beej. If they took a short run into a buffer from the passive, then that should give the same results as using the blended o/p as well (ie less hf attenuation?)

Yep, thanks!

 

[Platypus]

I should be able to make clips this evening... anyone else notice this?

 

[beej]

Dude- I'd wager it's cable capacitance making the difference (per my post above). So whether or not that's noticeable is going to depend on your rig.

I notice this on my piezo'd Morse if I use a long, regular cable and don't use the buffer on my board. I have an active/passive switch and can hear additional highs.

 

[bonez]

sorry to bring up an old thread but yeah mines the same when plugged into the mono/piezo the magnetic pickups have more treble then say plugged into the stereo/magnetic, in this setting its more muffled can tell more when amps on clean channel

would try a stereo trs cable but its almost impossible to fined one for guitar here in OZ
