The DOD FX10 BiFET Preamp was a popular pedal known for its clean boost capabilities and active tone control. While the original pedal had a switching mechanism, the FX10 Boost version removes it to provide true bypass functionality. Here’s a simplified schematic to recreate the core functionality of the DOD FX10 BiFET Preamp:“` +9V | R1 |Input —C1— R2 — Output | | R3 C2 | | R4 R5 | | GND GND“`Components:- R1: Input resistor (typically 1M ohm)- C1: Input coupling capacitor (typically 10uF electrolytic)- R2: Gain resistor (typically 1M ohm)- R3: Feedback resistor (typically 100k ohm)- C2: Feedback capacitor (typically 10uF electrolytic)- R4: Tone control resistor (typically 100k ohm)- R5: Output resistor (typically 1k ohm)This simplified schematic represents the basic circuitry of the DOD FX10 BiFET Preamp. The input signal is coupled through C1 and amplified by the gain stage formed by R2 and the BiFET transistor. The feedback network (R3 and C2) helps shape the frequency response and maintain stability.The active tone control is achieved by adjusting the value of R4. Higher resistance values will emphasize treble frequencies, while lower values will boost bass frequencies. The output signal is then attenuated by R5 before being sent to the output.By adjusting the values of the resistors and capacitors, you can fine-tune the characteristics of the boost and tone control to your preference.
