Please read:

The circuit is the same Hyde Distortion Filter found on the now discontinued Jekyll n Hyde dual filter boxes and the smaller Hyde DF euro pedal with the expanded CV. There is just two of everything.

We recently had an order for two Hyde Distortion Filter euro pedals so we custom made this dual box. By rotating the Serpa Custom box vertically we were able to fit two of the circuits side by side. It’s a different look and takes up less space left to right.

Since we are no longer taking orders for the Jekyll n Hyde dual filter box this seems like a nice alternative for folks that would still like a dual mono filter setup.

Unique to this version is an input link toggle. Use this to patch in a single mono audio source and send it to each filter. **Probably not recommended to link inputs while using the unit with a stereo signal. You may get phase cancellation!

And a “Misc” mod. The Misc mod is similar to the Misc mod on the original Jekyll n Hyde Serpa box that functioned as a cross resonance feedback mod. I say “similar” because the mod points were different on the Jekyll filter. Here we have two identical filters so I’ve only got one position to link the resonant feeds back. But it sounds e’ffin cool. It produces some unpredictable overdriven distortion that varies depending on what your feeding into each filter.

Two LFO outs. One for each slow drifting LFO.

LFO out can also be used as a CV input for the LPF (low pass filter) the filter will respond differently than with the dedicated LPF CV jack on the front panel. They can be patched to any of the CV inputs on ether filter.

But what is a Hyde Distortion Filter?

This is a low pass (all analog) diode ladder filter with two distinct pre-distortion circuits. Depending on how the knob is set there is a third district sound where the two signals meet.

This is a lower gain distortion so it works well with noisier synths. Since the filter is being overdriven by the pre-distortions you get a very unusual tonal quality. Tone can be affected by increasing or decreasing the output of whatever instrument or pedal you’re feeding into it.

You can bypass the distortions for a clean input. It has a very slow drifting LFO to keep the filter from sitting in a static position. There is a particular “worble” to this circuit. Much like vintage gear there is a touch of instability. You would hear this predominately when cranking up the resonance and clamping down the filter. Something not easily achieved with plugins or soft synths.

Knob controls:

Up: Pre-Distortion
Hyde: Filter
Fortis: Resonance
Down: Post-Drive
Nefras: LFO Modulation
“Y” LED: LFO Pulse
Blas: LFO Amount
Zeal: LFO Speed
React: Germanium Clipping

**Requires a regulate 18volt DC Supply. Standard negative tip with a min of 150ma. (not included) I recommend this one: the ECB004 You can buy it directly from Sweetwater.

The Hyde Distortion Filter can run on lower voltages for a dirtier sound. For instance a 12volt supply that can provide enough current will drastically change the sound. The lower voltage will affect the smoothness of the filter. Experimenting with lower voltages will not damage anything. Just don’t use more than 18volts.
