I’ve got three rickenbacker guitars and they all sound quite different. I decided to test the pickup resistance using a multimeter. My method was to measure from a cable at the output jack, with pickups in the guitar and the knobs up all the way (careful to ensure the blend knob was correctly set while testing the neck pickup

Ps I run all my guitars through a jangle box nano.
1981 360/12 with “toaster” pickups. This is my favorite. This is the one with the byrdsy chime. Sure enough both pickups register 7.2k. No clue where these pickups came from, but this guitar had a custom 12 saddle bridge installed in the 80s so I’m gonna guess maybe they replaced the pickups too? Wherever they came from they have the vintage sound.
1999 360/12v64 with “toaster” pickups. Although it has toasters they don’t sound the same. They’re warmer and don’t have as much sustain. Both pickups register 11k! That must be the reason for the different sound?
1989 330/6. Ok this isn’t a 12 string but I wanted to mention it because I have a question about this one too. It’s got hi gains. They’re ok. They break up with the amount of compression I like to use so I’m not super into them. The weird thing. The neck pickup measures 11k but the bridge pickup measures 8k. Is that normal?
My questions are:
Where can I find proper 7.2k toasters? I’d really like to try them in my 1999 360/12v64.
I’m wondering about the 330/6. Are toasters and hi gains different aside from their resistance? What would folks recommend for the 330 to open it up to some more jangle with lower output pickups? Should I try 7.2k toasters in that one too? My other thought was to put 7.2k toasters in my 1999 12 and swap the 11k toasters into my 330.
Anyways thanks for any tips/info you may have.
