Hello fellow UG'ers.

I recently acquired a set of Lace Sensor red, silver and blue pickups. After they arrived in the mail I decided that I would attempt to install them myself. I have no previous experience with solder and soldering irons but do have a basic knowledge of circuits and circuitry.
After removing my old pickups on my Hagstrom F300, I attempted to install the pickups but, unfortunately, to no success. As far as I could tell I had done it properly but after stringing the guitar up and plugging it in, there was no signal at all. I have a feeling it may have something to do with the earth wire as I wasn't getting any buzz when I plugged the lead in, but I really don't know.
It has an Atlas branded 5-way switch and two 250k pots, if that makes any difference. Maybe putting in higher output pickups would mean I should get 500k pots?
Anyway, here are some low resolution pictures for your viewing pleasure.

As you can see, the green and white wires have been soldered to the volume pot and the orange wires have been soldered to their respective terminals on the switch. The red earth wire is currently soldered to what I think is the earth terminal on the volume pot. I also tried soldering it straight to the volume pot with the rest of the earth wires from the pickups to no prevail.


This is a fuzz-alicious close up of the volume and tone pots.

Here is a link to the schematics off of the Lace Sensor website

It's a stormy day here in little ol' Adelaide


Anyway, summing up, could someone please tell me where I've gone wrong? Thanks

well i would go and check all your joints and one by one also i would solder your earth/ground tab to the back of the volume pot

Start with this suggestion. The tab should either be bent back and soldered to the back of the pot, or you could use a short jumper. 250k are fine, btw with the Lace Sensor set you have. Put a treble bleed capacitor on your volume pot to keep things from muddying up when you lower your volume, and make sure you raise the pickups quite close to the strings. Some have given those pickups bad reviews without setting them up properly. Follow the instructions on the Lace website for height.

I had a set identical to yours on a Strat. They sound really nice when set up correctly.

Check the volume pot and switch. I don't really see anything wrong with the rest of it but I can't see the volume pot or switch very clearly. It's also much easier to troubleshoot if you keep it neat. Cutting wires to size and cable ties and/or electric tape helps a lot. If you have a multimeter, check for shorts where the signal might be going to ground.

Check your signal path(s) through the switch with a meter as well to ensure you have the leads on the correct terminals.

Hey guys thanks for the feedback. I unsoldered everything, started again from scratch and everything works fine now. Not sure what it was but oh well, it's working and that is what counts! Thanks! Just needed to be sure I was doing it right.

Sometimes it's easier to just do that than troubleshooting. Especially with something as relatively quick as pickup wiring. Glad you got it working.
