Power supply design
Hi,
how to design a really low noise power supply ?
I built a lot of stuff but these never satisfy me too much...

I see a lot of players with so many pedals each with insane amounts of gain so likely no psu on the planet will fix that problem.
If you build intelligent circuitry you won't need fancy PSU.
I big issue is that a lot of PSU's are now Switchmode and many are just horrible noise makers.

Pedals designed for battery operation do not always have sufficient power rail smoothing to perform well on (some) power supplies. With battery operation this isn't a problem.
Some pedals "designed" for PSU operation don't perform well because the "designer" is clueless about good circuit design practice. These pedals are best avoided.
This can be made worse if there are other pedals that generate noise (those with digital circuitry can do this) and allow it to be superimposed upon the supply rails. This noise is just amplified by the pedal/s that have poor power supply noise rejection.
