Help! Picture Request - Cavity Macro Pic (must be piezo)

[HighGain510]

Hey guys! I just picked up my new JP6 with piezo and I'm not sure if the guy had it re-wired incorrectly or not as he replaced the stock pickups. Could someone send me a clear shot of the inside of their JP6 w/ piezo control cavity please?

Also, it's been a while since I've had a JP with piezo so perhaps I'm confused on the proper operation. Is there a way to run both the mag signal and the piezo signal through the same cable into an amp? When I run it through the mag jack and flip the piezo/mix/mag toggle I just get the electric signal. Any help? Thanks!

Btw just an indicator of how messy his re-wiring job was, here's a shot of what I was greeted with when I popped off the cavity:

Here's the Piezo pot:

Does that look how it should? Anything I might need to adjust to get it to work properly?

Check this out. . . . the wiring/schematic section is were you need to look.

The JP6 piezo diagram has your answer. Looks like you can use the mono input with a standard guitar cable to run a mix or switch between mag/piezo.

Here's a few pics of mine. Hope they help....

I use a 20' Horizon insert cable. It's stereo and Y's in the middle. One end marked in blue is the piezo and the other red for magnetic pickups. It works beatifully.

Which brand of pickups did he use? Most companies use the same color wires but they "don't mean the same".
As for your second question run a mono guitar cable in your piezo/mag (the top) jack to your amp. I have done this since I got my JP and I can go from piezo/mixed/mag with ease.

Awesome, thanks so much you guys that helps a ton! I think the issue might just be that he re-wired the pickups AND the toggle and perhaps didn't wire the piezo back on correctly. I'll take a look at the mags/mix/piezo switch tonight too, didn't even think of that.

Time to find a new "guy" perhaps?

High Gain, You can also email customer service for an actual wiring diagram.

Bingo. That's your best bet.

The original owner had the work done, not me. If it were me I could have done it myself (and wouldn't have touched any of the piezo wiring since you don't have to for just swapping pickups) and not had to worry about it!

I might contact them and ask for that info then, thanks guys!

Just re-soldered the piezo toggle... problem solved! Whoever he had do it had put the two wires too close to each other and there was solder touching. Issue resolved! Man, this is why I learned to solder myself.... can't trust all techs out there!
