Ive had problems in the past with pops when switching, last time it was the switch, before that it was a pull down resister. Ive just made a bazz fuss v2 great little thing it is too. but im getting pops at switching. im using no led and dpdt switching as in the layout in the gallery. I take it it must be the switch? or do i need a pull down or an resister on the input. these pops are driving me mad.  :'(

Are you using the switch wiring that grounds the board input in bypass?.  That is the first thing I would check.  You usually don't need pulldown resistors with that wiring.  It's available at GGG, and Gaussmarkov's page.  If the diagram is for a 3PDT, for DPDT just leave out the third row of lugs (which I think are for an LED anyway, as I recall).

Ok I'll have a look thanks for the pointer.

Ok I've had a look at his way of doing it but I can't see how i can ground the input of the board when bypassed without the 3pdt switch. Which I was hoping not to use in this build. Please tell me if I'm missing something? Thanks for your help
