This is an LTSpice Model of the LBP-1 boost pedal. This is needed for deriving the closed form analytic solution to the LPB-1 guitar pedal and building a SPICE numerical simulation.
The schematic above of the LPB-1 boost pedal uses a transistor that is not a default transistor model within LTSpice. Therefore, a ".MODEL" Spice directive is needed to include the proper transistor. f
A list of ".MODEL" statements can be found using the link below: Standard BJT List
Find your desired component, and create a ".MODEL" statement using a Spice directive.
