One of the last remaining Jekyll n Hyde dual filter units with a vintage meter. Vintage meters of this size are getting scarce and we need them for EFC Studio orders. I’ve had a couple of remaining panels so I’m trying to send them off to a good home. **This is not a b-stock unit. The meter being very old does have a scuff on the upper right side of the bezel. Vintage meters often have various imperfections. If your OCD and that will bother you please be advised.

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.

***We are no longer taking special orders for Jekyll n Hyde boxes. This is one of the last remaining units. I may assemble a couple B-Stock units if we have meters and parts over time. 


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.

***I do my best to give each box its own unique look and personality. Maybe the meter are so old they are haunted?
