[sdiy] pros and cons of SMT in DIY (was: Re: New Oakley Flanger/Chorus module)

Magnet wire is mechanically fragile and does not survive long unless you
leave the device completely alone. It's fine for testing or debugging but
that's all. IMO not good for a piece of musical equipment that gets played
or even... moved.
