Amp Potentiometer
Can i change the resistor values on this tone control circuit?
this is the circuit i'm planning on using with my pre-amp: http://www.afiata.com/wp-content/uploads/2010/02/active-Tone-controll-that-Boosts.gif
i have all the parts for this except the exact values for the potentiometers....the largest value pot i have is a 250k...not that 500k one that the circuit calls for.....would anything happen if i just cut all the pot values by half? if that wouldn't affect the circuit that much, i do have the two 50K and the 250k pots that would be required if i cut the values in half.
Can not see much point in the mid-range control. That is already covered by the volume control.
Personally, I would use the Baxandall circuit. It is a tried and true circuit:

You could reduce the range of the high control in your circuit, by adding resistance to R12/13. They generally have too much gain, any way. However, 500k pots are available, with a little more searching.
