The SI-01 features Two high-quality buffers.
The Second buffer is based on Low-Noise Op-Amp.
The SI-01 System Interface is designed to prevent the loss of signal level, high frequency and low end punch that is caused by impedance mismatch and cable capacitance.
Some Fuzz or Wah pedals don’t like to be fed with a buffered signal. For this reason, the first buffer can to be bypassed.
You can also avoid Ground Hum/Noise that may occur when two buffers are used for different signal routing, because the second buffer is supplied with fully isolated power.
