Gainpot, where to "implantate"?

[Oliver]

Hi All,

after my Holydays i am Back and directly have a question....  

I recovered an Error in my Circuits, as i everytime soldered my Transistors in the wrong direction.
Its cool, but the LPB works with it, but sounds a bit different and You can control the Gain with an 100K Pot at C from the Transistor in Series with the 10K Resistor. (it doesn't work with the Transistor in right direction!!)

OK, now, as i know, how to put the Transistor in, i played around with some DiodeClipping like the Electra Distortion.

I made an Electra Circuit, but used a 4.7M Resistor for the 2.2M One from C to B, used a 43K Resistor instead the 47K one at C to 9V+ and a 390Ohm Resistor instead the 680Ohm one from E to Ground.
Than i brought two 1N914 Diodes from C to B of the Tranny.
I used a 600hfe BC549C Tranny.

Its very loud and clips just like a high Gain Overdrive.

Now i want to bring a GainPot in the Circuit and dont know, where to place it.

Any Suggestions from You, Guys??

Thanx alot

Oliver

Well, I'm somewhat unfamiliar with the electra distortion circuit, but it would be easy to add a volume pot onto the end, of course... in terms of a gain pot, you could try putting a pot working as a switch between the output and the clipping diodes.  That'd be the best I can say not knowing the circuit...

Dear Experimentalist, there's nothing strange in such behavior of this cirquit. Hence ther placement of the diodes it is more a big muff section rather than electra.
For Gain control - either a potentiometer brom C to B instead of a fixed resistor, or a volume control on the input.

Hi,

and Thank You !!
I'll try that...

and for those who like to look at the Schematic of the Electra:
