With the return of one of our original builders (Jared Scott) back in the shop this last December I took the opportunity to have him help me clear out some of our remaining B-Stock JnH Serpa enclosures.

**This B-stock enclosure had a paint blem along the back side under the power jack. I slipped with the drill bit (ouch). Eventually I was able to touch it up so it’s not very noticeable. Later I asked myself why I am selling it as a B-stock. (LOL) …the scratch is still there. You gotta look hard for it.

**Because this was not a prepaid custom order we took a little liberty with it. We added this very unique upside down vintage jumbo meter. It reads “% Break” The needle movement swings in revers. It a little weird but works wonderfully. THIS IS A VERY BEEFY BOX! And its the only upside down meter I’ve ever used.

***Additionally we added a vintage “power failure” and “Control Panel” tag. You can thank Chris from @PreservationSound (Instagram) for sending these to us.

Another very unique Jekyll n Hyde Serpa box.

I’ve officially discontinued these boxes and we are no longer doing custom orders for them. This will be one of the final boxes. Only a few more enclosures left.

The Jekyll n Hyde box is a dual analog filter box with pre distortions feeding into the filters..

The Jekyll side is a transistor ladder filter with an overdriven pre-drive circuit (adjustable).

The Hyde side is a diode ladder filter with 2 different distortion circuits. A potentiometer brings those together creating a phased combination in the center.

The filters have that natural unstable “worble”. Especially noticeable when cranking up the resonant feedback into self oscillation. Something modern synths don’t have and VST/AU plugins don’t replicate well.

For fun (and sometimes confusion) I’ve added a cross resonance mod that feeds one filters resonance into the opposing circuit and vice versa. Really freaks things out. The results can be unpredictable. Perfect for sound design.
