OK...it seems I stumped the search engine with this one, so I'll ask the luthiering populace...starting with a statement...
I got a box of caps and resistors at work last year, some caps looking very much like bumblebees. I'd like to take a multimeter to it, but how do I measure microfarads with what I have? I don't see the uF/pF symbols on it...any help is great!

You either need a meter with a capacitor tester or another device called a component tester. The latter are pretty cheap and very useful to have around.

Something like this

Harbor freight sells a DMM that'll test them for like $4. I just got a decent $20, 6000 count DMM from Amazon and it works fine. I was having issues checking cable capacitance but it turns out I wasn't measuring correctly. D'oh! I didn't realize you tested them from one end only and not like you do when checking them for voltage/amperage/resistance.

Yes, I have a meter that also measures capacitance. I got it from StewMac when they had a sale.

I do tons of DIY pedal stuff and breadboarding. This is the jam right here:


Obviously I still use a meter for testing voltage, etc. but this component tester is very handy for everything else.

Aahh, good ol' "Mambo Sun"! I had to pull Electric Warrior out...
Thanks, y'all...Harbor Freight's a favorite of mine...I do have a DMM (digital multimeter, right?)

Will this one do the job, and where do I set it? (Don't get me wrong, I check pickups for resistance, batteries for voltage, but microfarads are something else...where do I "hook up"?

This meter has no capacitance testing section.

That's what I was afraid of...I'll check out StewMac and Harbor Freight 'n' see what I can find...thanks for the direction!
