content: Hey all!I'm about to start stocking some caps for use in guitar pedal building, and for a lot of values, like 2.2uF, the brand JB capacitors seem to provide good prices. I have, however, been able to find no good information on the reliability of this brand! They're website seems out of time (https://www.jbcapacitors.com/), but, of course, this is far more than what any other no name/low reputation capacitor brand would offer. They have many different series of caps, all the way up to flashy audiofoolery stuff. But it really tells me nothing about how much I can actually trust the quality of their average cap! Does anyone here have any information on them/experience with them?Thanks in advance

content: In general, cheap electrolytic capacitors are okay if you are not building a switch mode power supply or something that gets hot.That said, unless I was feeling extremely cheap, I would specify a Japanese, American or European made electrolytic capacitor, given they are typically more available from normal distributors, have better and more trustworthy datasheets and cost generally very little extra, so it doesn't matter unless you are building hundreds to thousands of a product.If you are talking about non-electrolytic capacitors, the difference is even smaller. Ceramic capacitors are essentially jellybean parts, though the likes of Murata, TDK, Samsung will typically have higher density and higher performance capacitors available in the same package. For anything in a safety application e.g. class X/Y caps only go for good brands. For generic polyester/polypropylene/etc capacitors I feel like there is little difference but have very little data myself.
