I have a Blues OD in a scene that I swapped the stock silicon 1N4148 diodes with the new germanium comrade D9Es and I just couldn't seem to get enough level after the swap. I turned the drive and level all the way up, and it still wasn't driving like it would with the original silicon diodes. For kicks, I created a quick scene with just input, drive, and output blocks to test the relative levels. With the original diodes, I was peaking out at around -3 dB at the output; with the germaniums, I was peaking at around -15 dB (for a 12 dB difference, which is a fairly substantial drop). Is the expected behavior for a silicon to germanium diode swap in the drive block?
