This is an analog compressor based on the famous “Ross Compressor”. We modified the circuit to be extremely transparent and reactive to the musician’s touch. By adjusting the Release control you can vary the pedal’s dynamics.

The Soul Pressure can be powered by a high quality stabilized power supply or with a regular 9V battery. To replace it remove the four screws on the pedal’s side. The accepted supply voltages range from 9V DC to 12V DC. By increasing the voltage the effect will respond more dynamically. The pedal has a standard tip negative connector (the same as used by Boss pedals). The pedal has a true- bypass on/off switch. It preserves the input signal even when switched off.
