Cloak & Dagger

ARP 2600 Post-Lawsuit Filter + Distortion

Cloak & Dagger is a fully analog filter and distortion module in 12HP for the Eurorack modular system. Based closely on the classic and coveted ARP 2600 "post-lawsuit" 4-pole lowpass filter (Submodule 4072), some modifications are introduced including an output buffer stage to compensate for the loss of low frequencies at higher resonance ("resonance compensation"), temperature compensated 1v/oct tracking, and two additional attenuverting CV inputs for controlling the cutoff frequency.

Two independent drive circuits are also on board which can be set to drive the input ("pre-filter"), drive the entire output ("post-filter"), both, or fully bypassed. There's an initial drive level control as well as a drive level CV input with attenuator.

Drive LED color corresponds to currently engaged drive(s):

• Green LED = Pre-Filter Drive engaged
• Red LED = Post-Filter Drive engaged
• Orange LED = Both pre-filter and post-filter drives engaged
  (LED reacts to audio input)
