Hate to sell this extremely rare Eurorack filter but there's always more bills to pay.
In perfect condition other than some very minor rack-rash (see picture).
Fits in every skiff I've and travel case I've used which is rare for Plan B so that's extra nice (will upload more picture soon, or message me).

Very hard to find ,and very sought after module since Plan B has been out of business for many years.

Really sad to see this one go as it is hands down my favorite bandpass filter of all time.

Plan B - Model 11 Evil Twin Bandpass

Twin Bandpass Filter

Utilizing an all-discrete core comprising twice the vactrols found in the mellifluous Model 12, the Evil Twin's open architecture takes advantage of circuit nodes which would be buried inside op-amps of conventional filters: a capacitance-coupled Twin Feedback path which engages an aggressive yet stable distortion mode not available anywhere but the 11. Brought into the circuit via a switch, the Twin Feedback generates timbres normally reserved for tube-based distortion units


I Will ship all (conus) modules and pedals USPS priority 2-day, same or next day. No returns on international orders (sorry!).

If you have any questions please feel free to ask anytime.
Thanks for your interest!
