Removal of wire from PCB wire to board connector

Hello,

This is my first post on this forum, my interests are around musical instruments and their respective electronics, particularly Bass Guitars. I'd put my knowledge as limited but have 5 years experience working on the shop floor of electronics companies as an electronic assembler.

At the minute I'm looking to replace the preamp in my bass guitar (a Yamaha TRB). I have my new preamp, all the correct diagrams for the task and I know how to do the job - but upon opening the cavity of my bass, I've noticed the two pickup output wires are connected to the board with a 2 way PCB wire-to-board connector. Usually, they're just tinned wires soldered onto the lugs of a potentiometer. I'm unsure how to remove the wires from the PCB connector .

The two wires look like they are put in the connecter via crimp housing and there doesn't seem to be a way into the outer casing. Is there a way to release these wires? Or am I best off just cutting them free? The gripe i have about cutting them free is that it may leave me short on wire to reach the new preamp output terminals, can anyone help?

Thanks

Smit

 

Yes, I initially thought I'd need pictures, Im in work, Its something i will do when i get home.

I can show you what they look like on the circuit board diagram, I have links to that, but not physical pictures of the connectors.

Thanks

 

In the attached thumbnail of the wiring diagram , Ive highlighted in a red circle the connectors that are the issue. i know its only a drawing but they dont look much differnt in real life, theyre very plain. I'll get proper pictures up later.

Thanks

 

OK, here's some pictures of the PCB connector I'm dealing with, Its the red and white cables i want releasing from it (intact, if possible). I've took a snap from as many informative angles of it as possible. Hopefully i don't have to cut them, but if needs must....

Looking forward to a reply,

Smit
