@KiOgon I’ve wired it up like that and no sound came out apart from humming, and the same thing that happened with my P the hum got louder when I touched the strings so I’ll have a look at the bridge ground to check that but as part of the course I checked the pickups and they hadn’t gone open the neck is 12k and the bridge is 15k which seemed a bit high to me as aren’t active pickups supposed to have a lower output than passive? I did think that if it’s a problem with the preamp and not the wiring could I rip out the preamp and just put 2v 2t passive wiring in or wouldn’t that work?? But I need to try and investigate a bit more on what the problem is, if you’ve got any advice at where to start I’d gladly accept any ideas............😀
