Orange Matamp OR100 (ngspice simulation of the schematic)

SPICE model with DC power supply. Bass and Treble are set to 50%, all other settings are in the model name. If you have requests for specific settings, let me know and I'll run the simulation. Drive settings (4-position rotary switch): 1) Studio 2) Studio + High-pass filter 3) Stage 4) Stage + High-pass filter "d" is Depth (i.e., FAC, a 6-position rotary switch), "v" is Volume (i.e., Gain), "boost" is Boost (i.e., H.F. Boost/Presence) Negative bias trim pot is set to 66%.
