Cold sweat neck....have BKP sent me a bridge?
« on: August 26, 2011, 12:26:12 PM »
Got hold of my BKPs, sent the guitar over to a tech since the active EMGs and pots were all replaced with the correct impedance push/pulls.

Got a call from the tech saying there was a wierd mismatch with the labelling on the pickups...both the warpig and cold sweat I ordered have a little tag with "bridge" on them.

I ordered a bridge alcino v warpig with a neck cold sweat to be used as a pair, the BKP boxes were marked correctly- long leg, 4 conductor, warpig bridge and cold sweat neck respectively.

I checked the warranty cards insdie each box and the DC was written down in biro for the cold sweat as an Alcino V 8.3kΩ "Bridge-Neck". This checks out with the BKP page detailing the cold sweat neck DC. Given the the bridge cold sweat is a ceramic 13.7KΩ pickup I chalked the little plastic label down to a simple error.

Now I've got the actual thing I'm not so sure...Although I've never played a cold sweat, the neck should have a pretty strong treble response, or at least feel brighter than a warpig bridge. That said, it really doesn't sound like it, the neck sounds completely mellow almost muted- I do have a multimeter- but I paid quite some price for the tech to fit and solder everything to the new pots and am really aprehensive above taking it all apart to test.

I've double checked I'm not being stupid and confusing my pickup selector position with the wrong pickups. I can knock my knuckles against the bridge pickup selected and get the appropriate "ring". Likewise with the neck.

Is there any other way you can suggest I check/test this without resorting to desoldering everything? If needs be I'll do it and send it back to the folks at Bareknuckle to double check, but I'd really like to avoid it.

use a DMM to check the resistance of the pickups - a neck CS will measure around 8.5k while the bridge CS is much hotter at around 13.5k.

the CS neck should be quite a bright pickup, especially with the volume rolled down.

what resistance are the volume and tone pots? - they should be 500k

Yeah, I've got 500k push/pull pots in the form of 1push/pull for the bridge, 1push/pull for the neck and 1x500k master tone.

As I wrote above, I don't really want to unsolder everything in order to check a resistance...am I able to check it without actually disconnecting anything?

And yea, the CS neck is not bright...at all. It's mellower than the warpig bridge and sounds like a gibson les paul bridge pup.

you can use the multimeter on a guitar cable thats plugged into the guitar

just measure across the tip and sleeve and switch pickups!

cold sweat neck is quite warm and bluesy - think of the solo in Whitesnake's Is This love

If you want a bit more bite raise the polepieces in the screw coil just a little - maybe match the fingerboard radius

What distance is the pickup away from the strings?

Looks to be solved. I grabbed the multimeter and had some trouble reading it off in the right spots at first, as I wanted to avoid taking a reading across the wrong sections with it all soldered together....SO!

Neck dials in at 8.2kΩ
Bridge dials in at 21.3kΩ


This is basically what it should be for a coldsweat neck and a warpig bridge. The tech had set up the pickup heights to "what he thought was nice", which was the lower output coldsweat neck pup set way back in to the body and the high output bridge rustling up against the strings.

Did a bit of adjustment and hey presto! The coldsweat is still bluesier and fuller than I expected, but I'm far happier with the balance now and I literally took a meter reading, wrote it down and came back every 5 minutes cross checking different spots to make sure it was right for a couple minutes hours.

It's an alright mix imo, I think having the coldsweat as full as it is will lend itself to some much smoother playing. I think it's safe to say panic over.

time to bask in the glory and first, and certainly not last, BKPs.
