I work on electronic security and locking systems. Some of the manufacturers include resistors, diodes and varistors (MOVs) with their hardware, which means I've ended up with a sizable stock of particular components. The resistors obviously can be used in pedal circuits, especially the 1ks. Are the 1n4004 diodes good for clipping? Has anything ever seen an MOV used in pedal building?
I dont have a bread board, so testing these things isnt that easy to just set up.
I work on other systems that I will be farming components off of as well. There are transistors and ICs to be had.
Building with farmed parts is extra satisfying.
Thoughts?

Absolutely. The forward voltage is closely comparable to the smaller silicon diodes (1N914, 1N4148) commonly used for signal clipping, and 1N4001's have been used for clipping duty in several BYOC kits. According to the published specs, the only difference between the various 1N400_ series of diodes is the reverse voltage level they will handle, which increases with the final digit. So while 4001's are rated at 50V, the 4004's will handle 400V. You probably won't exceed that in a pedal! ;)

I haven't personally seen varistors used in a pedal, but that doesn't mean that they aren't....
