They should make other components with variable values

Where is my varcapacitor, or my varinductor, or vardiode

@charlotte there are variable capacitors, used to be in radios for the tuner.

I have a few variable capacitors, and I've seen variable inductors before. Not variable diodes though, but for guitar pedal building it's not uncommon to switch between an array of different diodes for their forwards current for assymetrical clipping

@miifox in principle you could create a variable diode using a variable gain opamp, a diode, and a variable resistor

Yeah but it's not only the forwards current they play with, also the kneel function afaik. Plus if you can get away with a single diode instead of an opamp and a resistor, it's a win

Also this argument could go for variable *anything*. You can make basically anything with a variable resistor, an opamp and a few resistors and capacitors, but sometimes you just want to quickly try out a few values
