FYI - Article that Explains Bias, Bias X, Sag, Hum, and Ripple


Recommended Posts

The article is called Understanding Helix Amp Parameters, and it's posted on inSync. The article also explains ways to hear how changing parameters changes the sound - for example, how to use the 4 OSC Generator to hear how changing Bias affects the distortion characteristics. Another part tells how to hear sag in isolation so you can compare the sag of different amps easily.


I hope you find the info useful!
