Title: Fast Track 1 or Chopper? Wrong label?
Post by: Eliton on May 22, 2017, 08:50:01 AM

Hello guys!

I recently bought an used DiMarzio Fast Track 1 and I'm thinking that has something wrong with the pickup.

On DiMarzio website the FT1 has 5.8k resistance but my pickups has 9.3k on multimeter.

There is something wrong with the pickup or can be another model? Maybe the Chopper .. DP184

The label on the back from the pickup is marked DP181 like the Fast Track 1.

I have other chopper in the bridge position, and it has 8.7k.

Do you have any ideas what's going on?

Since the date stamp on the pickup says "1991" it cannot be a Chopper since that pickup was only introduced in 1994. If a FT-1 has a series resistance reading of 5.xx kohms there is no way to get a 9.xx reading out of it unless it is broken. But a broken pickup usually does not give a reading or one that is much higher so it may be a mislabelled model. Could be a FT-2 which has a series reading of 18k - if you took a reading of just one coil.

Between which wires did you take a reading? Series coil wiring is Black+white together, and then take a reading between green and red.

Thanks Stephan!

I found these pics on internet:

The same patent and the same year.

I put the black and wire together and take the measure using the red as hot and green + ground.

On last Sunday I installed a push pull and I split the both pickups, reading on multimeter was aproximately 4 - 4.5k. So, the bobins are ok...

OK I see.

Seems like DiMarzio uses the same bottom plates for the single coil sized rails humbuckers so that the date 1991 is meaningless.
In that case and given the DC resistance measured your pickup could well be a mislabelled Chopper.
