Hey guys, I have just recently gotten into building some pretty simple DIY stomps, namely, a Jack Orman design MOSFET Boost (http://www.muzique.com/schem/mosfet.htm
) and a passive A/B line switcher. My current problem/issue concerns the A/B box.
My current pedalboard is set up like this:
guitar->A/B switcher-> [line A: Compressor->Chorus] [line B: Overdrive->Distortion] ->Delay->Boost->amp
At every given live playing situation, at least one pedal from either side of the switcher is kept on.
I have read on a DIY forum somewhere that in order to get rid of the popping sound I get from switching between the two signal loop chains, I have to solder 1Mohm pulldown resistors to ground on the respective loops' returns, and so I did. It did significantly reduce the popping, but not completely eliminate it. If left "bypassed" for too long one side will always manage to "charge up" and give a softer, but still bothering popping sound when I switch it in.
Should I reduce the resistor value to something like 500Kohms? Will this affect the signal integrity of my setup, considering that the parts of the A/B switcher circuit that have pulldown resistors always see an effected signal? Is there a better way to solve this popping issue? Please help a brother out!
