Notch filter in Neutron Filter

[bioark]

that is my question.  
since I do it?
Gracias

Do you mean "como lo hago"

The Neutron schematic shows the lowpass, highpass, and bandpass outputs going directly to the switch and C14.  To make a notch filter, you have to mix/combine the highpass and lowpass outputs together.  To do this, you will need to passively mix them.  To do THAT, you should place a 1k - 2.2k resistor in series with each of the bandpass, highpass and lowpass outputs.  This will not affect their normal functioning and will let the HP and LP be mixed equally when they are both selected.

OK, I can't get this to work.

My Mutron III clone is made after this schematic. I tried the notch filter as stated above with a 3x 4 throw switch (1x 4 = LP, BP, HP, the other ones are not connected except for the last ones (nr. 4) that will switch the LP and HP together.

Hmmm, bit weird example; here's a pic of it:





All I get at this stage is the normal "bypassed" signal, no kind of filter. The other filters work

Anyone help??

ADD, not: short

I searched around and found the Anderton "Super Tone Control"; should I use different resistors for the HP and the LP filters (before joinig them)?
