Filters

Filters shape the sound of a subtractive analog synthesizer and have been central to sound design since the legendary Moog Low Pass Filter of the 1960’s. At AMSynths we having been building a wide range of filter modules for the last 10 years, some would say it’s our area of expertise!

The designs separate into 2 main groups; discrete designs from the 1970’s, and OTA designs based from the 1980’s.
