I built a guitar pedal which looks like this (the schematic is a clone of a Tube Screamer) and I have a question regarding something unusual I discovered.
There are two diodes, D1 and D2, which provide soft clipping. It turns out that removing one diode improves the sound significantly, making it less compressed and still very nicely overdriven! There's suddenly much more bass and details.
However, removing both diodes makes it too fuzzy and uncontrollable. Obviously, the removal of just one diode means that only one half of the signal gets soft clipped, and the other half is clipped through the op-amp.
Are there any other distortion pedals that utilize this fact? Am I doing something wrong? Did I discover something new? How would it sound if you could mix three kinds of signals - one clipped with diodes, one completely without and the clean signal and vary the proportions? Does any guitar pedal utilize this?
