WTB extremely hot and cheap humbucker, working or not

xscaramanga · June 2021

I'm looking to cannibalise a hot humbucker to make a dummy coil for some very hot Strat pickups (10.4k-11.5k). Dummy coils work best when they are a similar DC resistance to the pickups, so I'd need a humbucker of around 21k ideally.

Because I'm going to take it apart I don't really want to buy new, but an Irongear Metal Machine would be ideal. Does anyone have a stupidly hot humbucker sitting unused? If it's got a damaged baseplate, one coil not working, or leads cut too short, that's not a problem!

Cheaper the better. Colour, tone quality, and condition irrelevant (as long as at least one coil is functional).

Actually you need an inductance match for effective hum cancellation, not a DCR match. You want to match the number of turns (better to overshoot it as the lack of metal inside the coil drops the inductance relative to the pickup). You'll want a humbucker of about 10,000 turns on one coil - which isn't really produced, as that is extremely high. Your 21k humbucker has about 7000 turns of 45 awg on each coil.

I have some old P90s laying around that would probably be most appropriate.

Ha! I've just bought something off a fellow forumite without seeing this. Ah well, guess I'll give it a shot now and see if it's any good. Thanks for the info though, @Alegree . I don't think I could fit a P90-sized dummy coil into my guitar without substantial modification. Could you make your Silencer dummy coil with the right inductance, if given the specs of the pickups in the guitar? And (thinking of a different project I have in mind) would your standard Silencer still fit in a Tele control cavity if one of the pots is a push-pull?

Given it's exactly the same coil shape, it'd be easy to make and the best possible match (although there's a diminishing returns when approaching perfect hum cancellation, an offset of 1-2,000 winds is pretty much a negligible amount of hum.

It probably wouldn't fit. I think the best bang-for-your-buck in terms of hum cancellation to size ratio would be a Rivoli bobbin, as they virtually have no core.

Howdy, Stranger!
