MY JP refurb project Part 2

**Spudmurphy** · 02-15-2009, 06:26 AM

A little while ago I started this thread about my JP refurb project
http://www.ernieball.com/forums/musi...b-project.html
So just to get everybody up to speed here's what I did next:-

The piezo switch was shot and was totally U/S so I managed to get another one.
When it turned up I was surprised to see that it had the wiring loom all attached to it

The wiring goes from the switch to the main control cavity, and the wire felt really tight. I had to remove the neck pickup to reveal the piezo wiring running under the humbucker legs to a hole that led to the control cavity

I did have a proper wiring diagram for the Pet, but I also made my own diagram (I know it's not up to Beej's standard but it was Spudproof)

Just to go back a step - I had to rebuild the Bridge unit with new piezo saddles which I had to solder to the PCB. The factory solder joints were soooo flat - must have been done in a solder bath? Mine were initially a bit more proud, but I felt that they would still not short out in the recess machined into the trem block - I installed a cardboard "washer" between the PCB and the machined cavity also put a small piece of tape in the machined cavity to make sure !! This picture shows the pcb prior to the solder joints being cleaned up and made flatter and neater.

Underneath the bridge pickup was all this cardboard to raise the pickup height.

Just before I started to bolt the neck back on

Neck going on

The guitar has now been set up, the intonation is spot on, in the 12th and 24 fret positions.

The piezo sounds great and I have just taken a family shot of all my balls which I'll post soon.

A big thanks to Simon in Cardiff Guitars who helped me sort out a problem yesterday - no power going to the Piezo Pre amp.
Cardiff guitars have a very sweet green BFR LUKE in stock and a lovely LE 05 Silo (Butterscotch)

Once again a big thanks to Fsmith who helped in a big way to get this guitar - cheers Fred also to GWdavis who also helped

Gonna let the guitar settle and check the set up over the next couple of days.

I notice I didn't get a mention

I held the JP body, while Simon pulled the new toggle switch wires through - an invaluable contribution me thinks

I kind of like the dark headstock with the white. Nice work!

+1 : I'm not a fan of matching headstocks on white guitars.

Great work Spud.

I reckon the JP is an ergonomic masterpiece.
A real guitar playing precision "tool".
