Pickup issues

In my Jazzmaster, the bridge pickup has recently dropped in output by a large amount. I don't have any idea why, but I know the problem is with the guitar as opposed to cables, etc.

Any ideas?

unlikely to be a broken coil if the sound doesn't drop out completely sometimes, but its not impossible...

what's the control layout? Switch, master volume and master tone?

its most likely the switch, jiggle the switch in the bridge position and see if you can get the full sound.... the switch probably needs retensioning or replacing depending on what style 3 way it is. If jiggling the switch doesn't get you full signal for a millisecond or two and its master volume and tone then that means its probably the pickup itself (however unlikely that is from the symptom you describe).

If you have money to spend just do a 'shotgun' repair. Gut and upgrade all the electronics from output jack to neck pickup with decent quality shit. Switchcraft jack, CTS 500k pots, mallory 150 tone cap, Duncan P90s. That'll reduce future headaches dealing with cheap Chinese hardware.

Shit, Duke, I'm sorry to hear you're having problems. Didn't know you picked up an RG, though, but good luck fixing it.

By the way, I believe Boom is asking for you in his own English thread.

Update: I found a loose connection, but I have no idea where to resolder, so I'll put up a pic on my gear porn and see if somebody can guide me, or I'll take it in to school tomorrow, and get some advice there.

You don't need to put it on your gear porn. Just upload the image to Imgur and post the link to it here,

if you post a pic I can tell you exactly what to do

I decided just to take it to this guitar shop, in the city, that specialises in fixing technical stuff (Because I don't trust myself not to f*ck everything up), and they worked out what to do pretty quick, and fixed it up. The beauty of guitars is there simplicity, sometimes.

Happened to me once before when some bellend decided to take the bass we use and unscrew the back plate. It messed up the action and I never knew until I took it to my local guitar shop. Fixed up free within five minutes. Learned something new that day.
