i'm trying to install my soapbar hot p90 into my guitar but whenever I start screwing the P90 in with the screws I lose signal somehow.
Does anybody know why this may be happening?
 
Re: Help installing my Hot P90 ;_;

its probably grounding out against something, what kind of guitar is it?

It's a custom warmoth strat with a universal routing, it's also been insulated with copper tape.
How would I fix the problem of it grounding against something?

try putting something between the copper and the pup. since its a soapbar im assuming you are screwing it straight into the wood?

Certainly something is touching something else that shouldn't be touching. Are all the wires shielded? If there is any missing shield, tape those wires.

My thinking too. Either a signal wire is exposed and shorting to ground when the P-90 is tightened down. Or, there is a faulty wire or connection, maybe in the pickup lead near where it exits the pickup, or where the lead is soldered to the pickup wire, and when the pickup is tightened down it puts pressure on the pickup lead and breaks the connection.

Thank you everybody for your replies, you've all saved my build ^_^
I decided to tape anything and everything that could potentially touch something else and it worked :D

Each pickup now works and sounds beautiful.. despite my middle position sounding a bit thin and wah-ish, if anybody knows why that may be happening I'd love to know why.
Thank you everybody!

Thin and wah ish is out of phase. Swap the hot and ground leads of the humbucker, as that is more likely to have a separate chassis ground. If both are braided 2-conductor then a magnet flip will be in order.

Since I'm a noob. I think I'll ask for a slightly dumbed down instruction haha
Should I swap the green & bare wires for where the black one is? Would that fix my issues
 
Re: Help installing my Hot P90 ;_;

nice looking guitar. what brand is the humbucker? different companies have different color codes. if its a duncan then the black/green swap is correct
 
Re: Help installing my Hot P90 ;_;

I have nothing to add. I just wanted to say you have a very nice guitar

Aye. It's a Seymour Duncan MJ made JB Trembucker.
I'll be cracking it back open next week to fix it ^_^
