Do you have a hum or other noise in your pedal(s)? A very likely cause is noise coming through your AC adaptors. Many cheap adaptors lack even basic power supply filtering, so any noise in your AC mains ends up coming through to your pedal.But don’t despair. Here’s a useful and simple project: build a box that will eliminate hum in your pedal caused by crappy cheap power supplies.
把平價的DC火牛電源Filter 左然後出來， 減少hum聲。
