BAT Cold War is our take on the classic Rat circuit with the ability to select different op-amp chips and six clipping options. For this version, we've used NOS (new old stock) LM308, and NOS Soviet UD1408 from 80th (Soviet reverse-engineered LM308 clone) operational amplifiers. You can explore different Rat voicing by selecting between 6 clipping options: boost (op-amp clipping - very loud), soft (op-amp feedback loop) BS170 MOSFETs (crunchy tones), soft NOS AAP-153 Germanium diodes (perfect for Bass), hard Silicon 1N914 diodes (same as classic Rat), red LEDs (like Turbo Rat), and NOS Soviet D9 Germanium diodes (similar to Your Dirty Rat).
