Jumpers

There are two jumpers on the upper PCB, labelled JP1 and JP2. These control the nature of the 
dry/wet mix, as follows:

Without the jumpers ftted, the mix is a linear crossfade of the dry and wet signals – at 
the halfway point, the output is 50% wet and 50% dry.

With the jumpers ftted, the halfway point is 100% wet and 100% dry. Below halfway, dry 
stays at 100% and wet fades of as the knob moves towards '0'. Above halfway, wet stays 
at 100% and dry fades of as the knob moves towards '10'.
A suggestion of when this is useful: say you have the flter wound up to fairly extreme 
high pass with lots of saturation. This mix option lets you bring in the flter sound to add 
more 'hair' to the raw sound, without losing all the lows and mids.

Normally you would either ft both or neither jumpers, but you are of course free to do what you 
feel gives the best results.
From the factory, the jumpers are in the 'ftted' position.
