which gives us the greatest range of different effects. The LFO offers eight waveforms, including two
random waveforms.
Furthermore, the PCB provides for addition of an expression pedal to allow the filter to be used
like a wah pedal (but don’t expect a replacement for your Clyde McCoy - this is a whole different
thing!). The expression pedal can be used as well as the LFO modulation, or with Depth at zero, by
itself. There is also a Sync input for the LFO which allows the LFO to be kept in time with an
external clock from a sequencer, drum machine, or another LFO.
