MutronIII
Zeta Sound clone of the Mu-Tron III. A wonderfull envelope filter with lots of settings. The soundclips are in different, rather extreme settings.
MXR envelope filter
A clone of the MXR:s filter. A bit moded in the frequency and it has a “reverse sweep” choice with the switch. No soundclip.

Mad Quacker
A nice yet simple envelope filter. It can be found on the web as Nurse Quacky, but the Zeta Sound version uses it’s own circuitboard layout. The soundclip is not from a Zeta Sound pedal.

Ross Compressor
I’ve tried two versions of this one, one like the original and one with a bright mod. To my ears the bright mod is the winner.
