Hey GaussMarkov,
Thanks for the project, what a gorgeous sounding pedal. I used 2 LED's with different fv's (1.8 and 2.0V) to give me some asymmetrical clipping and and to clip at higher voltages than the 1N914's - made these ears happy

Thanks again.
PS. I would love a noob reverb pedal project - just in case you are looking for ideas LOL.
