The tone pot is not working on the piezo on my 2020 or my 2027's, so then yours must be modded, well , anyway it doesn't really matter.

I removed the volume pot and replaced it with a 100kohms resistor, and a shorting, so it will always stay on full volume, and I rewired the wires that used to go to the toggle switch.

Post the diagram????? are you mad?, it took me days,
Just kidding, but I don't have it on this computer. I'll see what I can do later on.

Re: Jem Brmr Piezo Project with pics!

your making me doubt myselfy here... I (completely) rewired my 2020X to run a sinlge stereo output... (had to use a push pull to disengage the battery cause I couldnt get a stereo barrel jack with a switch contact) I thought i left most of the ctrlX intact... but its entirely possible that I hooked up the tone pot to the ouput of the piezo and magnetics... but my 2027 is stock so Ill check that later on ...

I have a piezo lo-pro that has been itching for a project... if I can find the right neck. I never thought of hardwiring the ctrlX and stashing it in the output jack cavity so thanks for the inspiration!

The only thing I would add is a simple push-pull mod (Im sure you considered it already) which would give you piezo in parallel with the mags over all switch positions...

I know, I've been looking for those for quite sometime now.

I think there is enough space to have a push pull pot where the volume pot is, so that option should be possible.
I never use the piezo and magnetic together at the same output jack, so I didn't care, but if I get my hands on the previously mentioned stereo jack, that fits the Jem, I could use a Y-cord to split the signal to different amps, then it would be interesting to me.

Re: Jem Brmr Piezo Project with pics!

if you PM "gitarrero"... I think his name is oliver .... he knows a guy who will make them (by modding a switchcraft stereo I think), but generally doesnt offer them for public sale so they are pricey (~$30).

I run a single stereo cable to a splitter box ... one side goes to my mag rig and the other goes to the PA via an acoustimax preamp. works very well... would work better with the switch contact jack though.... one less switch

The wiring diagram as it is on my guitar.



This is the same wiring as above, with added push pull fuction to get piezo and magnetic together. I haven't tried it but I'm sure it will work.

Enjoy
