Irish ES-1 / 335 Copper Top

Cheers for the info Simon, much appreciated 🙏
Thought I'd be fine with the humbucker but wasn't sure what to expect from the vanson p90. Might try without but add a longish one to the back of a pot that'll be ready to feed up to the bridge if needed so the whole harness doesn't need to be removed again.
Have a tele missing the bridge ground and there is a slight hum until you touch the strings. Easy fix but not got round to it. Makes the big muff even more wild

That doesn't sound like a missing ground, it does sound like it's grounded or you wouldn't reduce the hum level by touching the strings. The baseplate on the bridge pickup is grounded and the mounting screws pass through this and so normally end up grounding the bridge by default. I prefer to add a definite ground wire to make sure, but you can normally get by without one. A multimeter to check the resistance from the bridge to the metal of the output jack is all that's required to see if you have continuity or not.

(Note that some cheap Tele bridge pickups lack the metal baseplate that makes up such a part of the Tele sound, so these would definitely need a bridge ground wire).

Earth and positive on the jack arse-about-face?
