Question: If the forward voltages between two diode types were made to be similar in value, would there still be a tonal difference?

Clipping diodes are essential to most overdrive pedals available today. It's commonly known how the different diode types affect the drive characteristics. But, there is a fundamental difference in what is called the "forward voltage" between the diodes that causes it to overdrive differently.
After comparing the overdrive tone between different diodes, I created a circuit where 4 silicon diodes give a similar forward voltage to an LED. Similarly, 2 germanium diodes against a single silicon diode. Let's see if there is a tonal difference when the forward voltages are of similar value.
