SwedishLuthier Posted March 18, 2007 Report Share Posted March 18, 2007 (edited) I recently got myself a Torres “Midrange and Tone Switch” http://www.torresengineering.com/midandtonswi.html As I understood the function it would act as a normal tone (treble attenuator) in the “push” position and a s a mid cut filter (band pass) in the “pull” position. When trying it out the tone control position is maybe the best tone control I have ever heard. Cuts very good but only the parts I would like and leaves much mid in the sound. Now the problem: When pulled it DO cuts a little mid, but it still cut as much treble as in the push position. If I draw the two circuits they look like this (one schematic and one as it looks): Now to my question: What can I do to get this circuit to act more like a “true” mid cut (not cutting the treble) in the pulled position? I am no electronics wizard and I cannot understand what the resistor is doing in the mid cut circuit. As I under stand it (and the way it is described in books by Hiscock and Brosnac) the inductor acts as a low pass filter that lets everything beneath a certain frequency through and the capacitor acts like a high pass filter that lets everything over a certain frequency through. When connected in series and inserted between the “hot” and the ground the capacitor and inductor bleeds the mid to ground and let the treble and bass be unaffected. I would be very happy if anyone had any suggestions for modifications to this circuit. I don’t really have access to a lot of different inductors. The best mods would be if I only have to play around with capacitors or resistors. Edited March 18, 2007 by SwedishLuthier Quote Link to comment Share on other sites More sharing options...
