DIP SWITCH SETTINGS
Use a DIP switch for versatility, or wire jumpers to create a fixed configuration. With the switch in the "ON" position, the circuit is closed (shorted), which is the same as creating a permanent connection with a wire jumper.
Original effect setting
S1 OFF, S2 ON, S3 OFF: High input impedance and flat frequency response.
Input impedance
S1 ON: Lower input impedance to minimize the switch "pop" noise.
Frequency response.
S2 ON, S3 OFF: Flat frequency response.
S2 OFF, S3 ON: Flat response at low gain. Light treble booster at high gain.
S2 OFF, S3 OFF: Light treble booster at low gain. Treble booster at high gain.
