Apologies of this bores someone but whats the usual protocol for setting up a wet dry knob on a circuit? I have a delay circuit on the breadboard, ive buffered the input, sent it to the delay aswell as to the 1st pin of a potentiometer then the output of the delay to a buffer then to the 3rd pin of potentiometer. Output is from the middle pin of potentiometer. I have a feeling the problem is where the output from the input buffer goes to both the delay and the pot how do you get two outputs from one output? Resistors?

Cheers

Is there a different way to wire up buffers with guitar as opposed to synthesizer signals? I am having trouble getting this to work. I took a month off electronics so im a bit rusty. I've got a fuzz circuit and a delay circuit I am trying to blend, I only have TL072's

edit: i've got the fuzz coming through now but theres a constant hum that disappears when I cut power rail to the op amp. The sound is clean when its not connected to 9v?? The bias voltage is connected to pin 3 is that all thats required?
