Title: Stupid question: zero ohm resistor
Post by: Bucksears on August 21, 2007, 02:44:27 PM
I've never used a zero ohm resistor, but is that the same thing as just using a jumper? I've added a scoop toggle footswitch to bypass the mid-pot, but I'm not sure if that is the correct way about going about it.
Can I toggle between the mid potentiometer and nothing? i.e. one side of the DPDT switch is just a jumper and the other side goes in/out of the mid pot?

Thanks,
Buck

0 ohm resistor = Fancy Jumper  :D

It's a jumper with aesthetic considerations... A resistor looks better than a jumper any day...

A 0-ohm R make sense if the main parts are placed by a nailing machine, the machine cannot nail a jumper and the belts can't be supplied with jumpers either.

Also in the future you can change the 0 ohm to some other value if need be.

Zero Ohm resistors are intended to be used with auto-insertion machines that would normally be inserting resistors into the board. This lets the machine also insert jumpers without any additional tooling. Some sneaky people also use them as a convenient way to make fake resistors.... just paint some extra lines on there and....
