Further information from nonlinearcircuits:

The Feague is a 4 pole VCF and quadrature oscillator with 0, 90, 180 & 270 degree outputs. It is based on the design in electronotes 41. 

It features a lo/hi switch to run it at audio rates or LFO rates, plus a nonlinear Q pot which makes for interesting behaviour when using as a VCF.  

When using as a QUO, the nonlinQ pot is used to increase the amplitude of the output signal, which is known to shrink somewhat at low frequencies in these kind of oscillators.

Assembled modules are built to order. They will be ready to ship within 1 week of ordering, usually I manage it in 1-2 days.

Inputs

SIGNAL: audio input 
CV: for controlling cutoff in VCF or frequence in LFO/VCO 
SYNC: sync in/freeze/hold control  
1V/OCT: for controlling cutoff in VCF or frequence in LFO/VCO 

Outputs

Each ouputs are 90 degrees in out of phase : 0, 90, 190 and 270. 
In VCF, the two outputs closest to the side edge of the panel are low-pass outputs, and the other two are band-pass.
