Ah, yes. Missed that.
Well, the utility that I intend it for is even less glorious. I had an idea for a guitar fuzz pedal that would eschew the usual "tone" circuit (usually just a low-pass filter) and replace it with a slew rate limiting circuit. The idea would be that the usual ugly upper frequencies would be attenuated by the slew limiter, and as a bonus, the harder you played and the more you clipped, the lower the high frequencies are in comparison to the original signal.
Haven't mocked it up yet, so I don't know if this approach smooths out the usual hi-gain sound any (I hate that high frequency hash that shows up on most pedals). I'm sure turning sines into triangles doesn't decrease harmonics any, but hopefully the amplitude will be diminished enough.
We'll see. This is all a part of my new custom pedalboard experiment. I know guitar effects are somewhat low-brow for this particular forum, but you guys are the best, so bear with me while I poke and prod about various goofy looking circuit fragments and ideas.
