This Envelope Follower will do the job (with pre amp for mic) > [@Envelope Follower with high pass filter (ARP 2600 )](https://lookmumnocomputer.discourse.group/t/envelope-follower-with-high-pass-filter-arp-2600/1182): > > Hi everyone! So i want to build Eddy Bergmanns ARP2600 Envelope follower on stripboard but I want to add an adjustable high pass filter to the input. Here is the stripboard: Where would you add that high pass filter? I was thinking adding it after the Preamp input / Bypassed input switch. A 100nF cap and a 100k pot with 100R resistor in series, would that work? How would you incorporate that? cheers --- _[View the full topic](https://lookmumnocomputer.discourse.group/t/module-requests/39)._
