Hi, here's my problem. I have a Cort GB74 bass, it originally had an active circuit, which unfortunately burned out. I'm now left with some spare potentiometers and a switch on the bass. I would really like to make use of them but I'm a newbie in these things (I have decent soldering skills but I lack knowledge). The bass is composed of a Single coil in the neck and a humbucker in the bridge. A master volume control, a J/H blend control, and a SPDT switch which changes between the north/south/both coils on the humbucker. A stacked potentiometer (doesn't work, i guess its a bass/treble cut) and a SPST switch (doesn't work either, I can't find any model with this switch). Do you have any ideas, resources I can use ? Here are the schematics but bear in mind that they do not reaaly match my bass (I can't find the appropriate ones on the Cort website and the support doesn't answer to my kind emails) Let me know ! Any help is appreciated.
