creating a mute switch

[firebottles]

I have a bass rig where I have put a 1/4 inch jack after all of the pre's .. where the soundman can attach a Direct Out... just before my poweramp. . as opposed to the usual "at the input, just after guitar"... this way my entire rig is going into the DirectOut. Well I want to put a mute switch just before that jack.
Most simply put, the jack resides between preamps and poweramp.

In case I need to switch something around I don't want a BANG to go to the board. Like last weekend.

Is there a type of switch that works best to make a quiet disconnect and reconnect? Is there a wiring scheme whereby I disconnect only the hot or ground to make it quiet? Both?

Thanks!

I reckon that if your preamp, PA board and poweramp are correctly designed. then all you need to do is to break the hot connection to your jack. A mini-toggle will do the job, or a slide switch or stomp box switch, although none of them are particularly sophisticated.

In saying that they are well designed, what Im assuming is that there are no floating capacitors at the input or output of those pieces of gear which can cause a pop when they get reconnected. But if there were, a high value reistor from hot to ground on each side of that switch might fix it (say 2.2M)
