this is my my circuit

i also did this:

EDIT
I removed this I'll just use trimpot instead
Adding a "softness" or clipping threshold control
You can put a pot in series between the signal and diode pair to adjust the clipping threshold of the diodes. This acts like a "softness" control. I saw this described by R.G.Keen.
This works well. You can also put the bounding resistor between the diodes and ground.
instead i put DPDT switch on pin 1
-0-0-0- (-pair of diode - pin 1 - 2nd pair of diode-)
-0-0-0- (-diode's ground - ground - 2nd pair of diode's ground)
on this part of the first link i gave is where i have a problem
Gain Control
The transistor's gain can be increased by a lot by bypassing the emitter resistor with a fairly high-value capacitor (4.7uF+). Or, a gain control can be added by replacing the 680Ω resistor with a 1k pot going to ground, with the middle lug connected to a capacitor as before. By using a lower value bypass capacitor (0.1uF-1uF), a treble boost can be added, although I find it more effective to just add a high-value bypass capacitor and reduce the value of the input capacitor for a treble boost.
i know how to put bypass cap in a fixed resistor, for what i know you'll put it parallel with the resistor positive side on emitter pin..
but in this case.. im using a rheostat..
which one is right?
pin 3 positive side and pin 1 negative side or pin 2 positive side and pin 3 negative side?
and i heard about making log pots out of lin pots.. i need it coz we dont have log pots here
i heard that you need to put 10% or 20% value of pot resistor in pin 1 and pin 2.. what if i'll use it as a rheostat? what if i jumpered pin 1 and 2 will it work still?
