Title: Pork Barrel dry kill
Post by: jonnygreentrees on February 01, 2017, 10:19:06 AM
I've now got a working Pork Barrel but before I box it up I was wondering if it is easy enough to add a dry kill switch so I can turn it into a vibrato as well?

Cheers

Just lift one end of R9 and put it to switch

Sorry for being an idiot but how do I connect it to the switch?

disconnect one side of R9 from the pcb and run a wire from the now disconnected side of the resistor to one lug of the switch. Run a wire from the other lug on the switch to the now vacant PCB hole.

A couple more question from another idiot:

1. Does it matter which leg of R9 the switch connects to?
2. Will an ON/OFF SPST do the trick?

Thanks in advance

1. No, it doesn't matter which side of the resistor you lift. The dry signal doesn't care if it goes through the resistor or toggle switch first.
2. Yes a spst on/off switch is fine for this. You could also use a spdt and leave one of the outside lugs disconnected, or larger switches as long as the 2 contacts you choose connect.
