Hi there,
could someone check my design to see if it wil work.
Did i put in the tone/precense control right, or should the distortion signal be buffered first?
does R5 alter the freq.responses of the tone control??
does the volume pot alter freq response?
main question is : can you put in a pasive tone control like i did here, just after any working circuit and right befor teh volume pot??
Thanx

I I understand your quandry correctly....
Yes
and Yes...
the volume and tone controls look 'usual', to me. If it does what you want it to then absolutley...Yes !
R5 looks like it's part of an R/C network there, I'm just beginning to figure tone control responses a little bit by looking at a schematic, most of the time I can get the tone knob to go treble as it's turned up, not down.
That is where I'd put the volume control.
What effect raising or lower R5 will have? I'd like to know that, if someone else posts about it, I'll probably be able to register the info,and remember it, however I KNOW I'd remember the basic formula for a resistor after a cap in a position like that's influence on tone/frequency shaping by changing it around and getting a cause/effect response to value change of resistor in an 'R5' type situation.
It will work but the output will be low, probably lower than you want. Remember that the diodes will limit maximum output signal (what us mortals know as clipping), and the tone control is a passive one, hence based on "selective signal bleed". Placed one after the other, these two will pretty much guarantee that your volume control will rarely be set below max.
Some sort of gain recovery stage would be helpful to provide a reasonable output level. Alternatively, use a litle more gain and LEDs or some other diode arrangement that lets a bigger signal escape the clutches of the diodes and the signal loss through the tone control will not be as noticeable.
