buffered kill switch

[Jet Judo]

My band mate plays with a noisy jaguar, and sometimes i want his guitar to shut up...  However, i dont want to sacrifice dynamics by having to use a  noise gate...  I would really like to build a simple kill switch pedal.  However isn't there a cicuit that can make it so that there is no pop when he hits the switch?  Can anyone make any recommendations?

thanks

Wire the switch to short the signal line to ground - that should prevent pops or clicks.

sorry, i am quite new to this...

thanks andi, that makes perfect sense...

ALSO, is there a way i can use an led to show whether the switch is engaged or not so that he won't be playing "acoustic" accidentily...

could anyone sow me a schematic/layout for this... I am sure this is the most simple pedal ever made but it will be of great use...

thanks

SPST will do the short to ground of Signal line.
 DPST can be used, one half to do the above, the other half to switch the LED, current limiting resistor and power supply circuit to complete or defeat.
 A DPDT can be used of course, leaving lugs not used.
 It should be easy enough to tell if the guitar is off though without an indicator..?

No probs. To a lot of people the obvious way to do it is just to break the signal line, but that will cause noise and usually the pops and clicks you're trying to avoid. Shorting to ground works much better.

Yup - as petemoore says, just get a dual-pole switch (it's basically two switches that operate together), and use one pole to short the signal line to ground, and the other to close the circuit on an LED and battery (plus you'll need a current limiting resistor for the LED - 1k should do).
