Bought a 70’s P electrics kit off eBay to replace my crackling 74 pots. Bit of an oddity on the new kit - volume tapers off super quick - bit like an on/off and the tone is like a volume - no tone change. Very weird! 
Any thoughts? I’ve checked all the earths etc, all seem in check.

If the volume is acting like an on/off switch then it sounds like  the volume pot has a linear taper instead of logarithmic. Can you measure the pot taper with a multimeter?

 

Also, do you have a copy of your wiring diagram?

Looks like the stamp on the back of the volume pot is A250, so is a log pot.

That’s what I thought. If it’s behaving like a linear taper then we’d need to see the diagram.

Sorry the late reply - it didn't come with a wiring diagram unfortunately. I have wired as per the previous wiring and know may way around the wiring a bit. They are A pots, and whilst now sounding a little better than previous, I'm still not overly impressed. I've emailed the eBay seller - yet to hear back from them. The tone appears to be the main issue now - whilst acting more like a tone pot now there is a significant volume drop when all the way down. I know this happens to a certain extent but I've not had a P where the volume has dropped this significantly. Kicking myself for not having bought a Kiogon  now 😂
