Kliche - diode removal?

Hi,

I finished building the Kliche Mini today and it's a great circuit.

Something odd happened though. I boxed the circuit and set it up for final testing, having made sockets for the germanium diodes (but I FORGOT to actually add them).

It not only worked, but actually sounded fine, even moving through all the gain and output settings. I have a few other Klone pedals that I have played extensively and nothing sounded significantly bad to me at the time of testing it.

After a few minutes, I realised I had forgotten to install the diodes and threw in a pair of 1N34As. It still sounds great - A/B tests against my Decibelics Golden Horse and I can't tell them apart.

I plan to test a few different diode sets in this pedal but before moving further - is it a feature of the circuit that it still works fine without the diodes installed at all?

I know the diodes don't play much of a role with the gain turned down - but I am really surprised that the circuit works at all with nothing socketed (let alone sounding ok with the gain turned up).

Last question - is there any chance I have damaged the IC? I did test the pedal with the gain high for about a minute prior to socketing the diodes and it sounded fine - in hindsight it was probably just the IC breakup.

Thanks.

Also worth mentioning that it’s totally safe to omit the diodes because they are hard clippers, so they don’t affect gain or bias of any other stage, they simply clip the signal after one of the stages in the overdriven path.
