Description

Edit description

The Jekyll n Hyde is a dual LP filter distortion box with enhanced resonant feedback. One Transistor ladder filter and one Diode ladder filter. The input can be linked to feed a mono signal into each filter creating a wide stereo effect. This sounds great with mono analog synths. Both filters have a pre drive/distortion, a post gain and germanium clipping. Each filter also has a slow drifting LFO for subtle modulation and CV ins for filter control.

The filters can also be used separately for stereo processing. Just unlink the inputs with the M/S toggle in the back. Depending on how you have it dialed in the you can create a very wide stereo field or a more natural one. Both filters have a different method of distortion in the pre-drive section. Jekyll is cleaner, Hyde can be made to be fully distorted. Official Website

One weird and wonderful box

"The Jekyll n Hyde is a dual LP filter distortion box with enhanced resonant feedback. One Transistor ladder filter and one Diode ladder filter. The input can be linked to feed a mono signal into each filter creating a wide stereo effect. This sounds great with mono analog synths. Both filters have a pre drive/distortion, a post gain and germanium clipping. Each filter also has a slow drifting LFO for subtle modulation and CV ins for filter control."

This is a very unique taste piece for me. It's not useful on everything as I tend to like cleaner sounds overall but it's wonderful for processing samples and roughing things up a bit. I tend to use it in mono more than stereo and I tend to use the Jekyll more than the hyde but I love having both options. It's great on digital sources where you want to add a touch of saturation and LFO drift. The build quality goes without saying, each piece is unique. I highly recommend it.
