Bartolini Mk1 wiring help!

had a friend drop a Cort A4 bass (bartolini Mk1's and mk1-4/f preamp) to me where he's swapped a couple of pots as it stopped working, but alas, still not working. I want to make sure he's wired these pots correctly first before doing anything too drastic (like rewiring this SOB). From what I can see everything else is fine from the preamp. He's swapped the volume push/pull pot for definite, but I also want to make sure that the blend pot is correct.

We just get a large amount of noise from the bass with an extremely faint signal and none of the controls actually work except volume on the push/pull pot, which itself scratches and cuts in/out whilst its being moved. I'm guessing there is a problem with grounding and power distribution throughout the electronics. The output from the mk1-4/f goes back to the main volume switch so I'm guessing the switch kicks the EQ in and out?

If ANYBODY can help pls pls let me know!

I know that this is an old thread but I'm having this same problem with my Cort B4 fl.
Have you solved this problem? And how did you managed to do so?
Thank you.

Can you post a pic?


Sent from my iPad using a bunch of electrons, copper, and probably some fiber optic cable
 
Re: Bartolini Mk1 wiring help!

I couldn't help it
I googled "bartolini mk1 wiring diagram"
and there are a coupla dozen

try that see if you can find your preamp

I found the ones for my Ibanez SR
not sure about your cort

look them over see what looks familiar
 
Re: Bartolini Mk1 wiring help!

I have the Cort wiring diagrams. I was just checking if the OP has solved that problem with his bass and if he can describe how he did it because my bass is doing exactly what he says and it would save me a lot of time and work if I had a starting point from which I can attack the problem.
