The Frostwave Resonator from Australia is in fact a "true clone" of the Korg MS-20's classic VCF analog filter section. It consists of a high and low pass filter in series, with resonance and cutoff controls for each, plus a balance control and bypass switch.

It looks like one big fat guitar stomp box! It's got four knobs to adjust the Frequency Cutoff and Resonance for each filter, as well as an overall Volume knob and Wet/Dry Mix knob.

There are also six 1/4" jacks on the Resonator for audio and control. A mono input, mono output, and Control Voltage (CV) inputs for the low pass cutoff and resonance and high pass cutoff and resonance. These CV inputs let you control the resonator with other analog synths.

This stomp box really is a cost-effective way to get the MS-20's classic filter to process your own synthesizers, guitars, bass, sampler, and vocals! It is used by Charlie Clouser of Nine Inch Nails.

I agree Skunk3 - and can I add, this is a silky smooth and also a destructively powerful analog filter. You may self oscillate to your hearts content, be careful with those speakers! I wish I had an MS20 like many of us, though this helps towards those sound manipulation/synth needs. We can only hope that Paul Perry comes back 1 day to build more well built and highly interesting sexy-boxes (Sonic alienator etc) I take my hat off to you and hope you are enjoying a well deserved break.

As you can hear in the vids, the filter of a monotron does not compare (and how could it with only one knob?)

I had both versions of the Frostwave Resonator and I have to say that it sounds pretty fantastic. Forget the Monotron... this thing sounds a million times better. I wish I still had mine. If you want that MS-20 filter sound without the huge investment, scoop up one of these. I made so many drunken recordings running TR-606 patterns through this. I would compare this to a Jomox M-Resonator, but IMO the Frostwave sounds better.
