I have a simple circuit that I have that outputs a squarewave to a mono audio jack. I hook this up to an amplifier (like a guitar or keyboard amp) with a standard 1/4" guitar cable. And I have a normally-open switch at my output that when I hit it, it connects my squareqwave output to the guitar amp. So, basically I hit the button I hear a tone.
My goal is to use this along with a slider or potentiometer to play different tones out of the amplifier, by moving the pot and hitting the button... and everything works fine, except everytime I hit the button I hear pretty loud clicks and pops from what I'm assuming is just the noise of the physical metal contacts of the switch hitting together...
Does anyone know a way to rememdy the initial contact noise I'm hearing? I'd like to be able to press the button as fast as I can and only hear the squarewave tone and no clicks.
much thanks!
