[sdiy] Tone controls

[xamboldt]

If I recall correctly that Paia/Anderton circuit is just a SVF with  
the LP, BP, and HP outputs going into a mixer. The Blacet Dual Filter  
was pretty similar, except the different outputs were on a switch. He  
was having a fire sale on those PCBs a while back - I don't know if he  
has any left.
