Low ESR Capacitors

[ac30irons]

Hey all, just got a new batch of caps but all I could get are low ESR. Done some googling and searching on here but can’t get a definitive answer as to if they are actually ok in guitar pedals. What’s people’s take on them.

assuming these caps have an appropriate voltage rating, - yep, they'll be just fine.

Usually the lower the ESR, the better. Equivalent series resistance is a non-ideal behavior of capacitors and is preferred as low as possible otherwise it interferes with filter points and power dissipation.

I’m not (someone with more knowledge can chime in) but they might even be beneficial in digital or circuits with charge pumps.. otherwise for most of our purposes I haven’t noticed any issues where I have used them in the past.

Yes, low ESR is usually a good thing

I use low ESR electrolytic capacitor, cheaper or good brand, in the power filter.
For signal, when I really have to use higher value cap, common electrolytic caps. For a better performance I use electrolytic made for audio signal.

Thank you all for chumming in. It would seem they are ok
