All analog, hand stamped, pure sine wave VCO, low pass filtered with a touch of class and apparently musical. These are the requirements of warp speed space travel; regular occurrences when dealing with Randy's hardware.
Changes worth noting. The FREQ control now offers a wider range and is appropriately weighted for better control of desired frequency. The low-pass filter is now voltage controllable via the CV/EXP input. Micro switches located inside the pedal allow the user to customize the function of the CV/EXP jack.
In short, access is given to either voltage controllable parameters (oscillator frequency and low-pass cutoff frequency) as well as the possibility of using the oscillator output to control other devices.
