What should the ohms read on each of the 2 pickups on an early 1970s' 4001 bass with a toaster at the neck? On my meter, which could be off, I'm reading 8k for the toaster neck pickup and 8.3k for thr bridge pickup. Thank you!

That sounds good, those readings are in the correct range.

1960s pickups were around 6k ohms. 70s pickups were around 8k ohms. the 4003 pickups are about 11k ohms. Some of the pickups from the late 80s were wound about 2k ohms hotter. The re-issue horseshoe is about 11k ohms. The 4003s5 bridge pickups are about 15k ohms, and the 4004 pickups are about 15k ohms when wired in series.

These reading can vary slightly depending on the pickup and the ohm meter.

So, the higher the ohms the higher (hotter) the output?

Not necessarily. There are many variables to output, including magnet structure, coil geometry, manner of windings, etc. About the only thing that can positively be said is that given the same magnet structure, bobbin geometry, and winding wire and technique, more winds can mean a little more mids from the resulting higher inductance of the coil, and a little less top end from slightly increased intra-coil capacitance.

Thank you for the response and info!
