Just picked up a nice sunburst road worn strat in a trade and love it but noticed when switched to the neck pickup the volume almost drops off entirely. Also scratchy sound when changing pickups? Any idea what would cause this? thanks
As far as the volume drop, first thing to check is your pickup height. If the bridge and middle are way higher, that could account for that. I would guess that's not the issue, but it's a good place to start.
Next thing to do would be check the DC Resistance with a multimeter. If you plug in your guitar and leave the other end unplugged, put one lead of the multimeter on the sleeve of the cable and put the other lead on the tip. Set it to read Ohms. That should give you the total DC resistance of the entire circuit pickups, pots, and anything else included. Switch around to different switch positions and record each. You might find that the bridge position is 6k and the neck is 3.5k - if that's the case the issue could be with the pickup.
Some Meters are automatic, others you have to set the level you want to read. But most pickups are between 5k and 12k ohms.
If you don't have a multimeter they're super handy to have. Here's an affordable option and a nicer option. I upgraded from a cheapy to a nicer one earlier this year and it was a good buy. $30 isn't bad for a nice one too!
