Volume Pots on A/B/C Box
« on: March 14, 2006, 07:08:56 AM »
I'm trying to design an A/B/C box (used as 3 in and 1 out) with a volume knob on the B circuit. The reason for this is I'm using a pair of headphones to sing through but they feedback really easily. I've tried them through a Ernie Ball volume pedal and when the volume is backed off slightly the feedback stops.
I want to try to recreate the Ernie Ball volume control/Pot within the A/B/C box.

What is the best Pot to use for this? I've heard Audio pots would be better than linear. Is this true?

What Ohms do I need the pot to be? I keep reading the 250K would be best for passive instruments?

Do I need any resistors or capacitors for the potentiometer?

Where would the potentiometer go? I imagine in between the switch and the B input/output...Is this correct?
