Re: Question about selecting bandwidth in diode clipping circuits quote: "...should expect something useful from sticking caps in SERIES with clipping diodes,..."     I think LXH2's Marshall Simulator had a stage like this (unfortunately his site is gone). His idea is when the clipping begins, the frequency response changes, like in a power stage with NFB.     On the subject of bass cut on the TS-9. When you pass a complex signal into a clipper the bass frequencies modulate the high frequencies.     " target="_blank">http://www.geocities.com/SunsetStrip/Studio/2987/100p1k.gif">     (Blue wave is input, Red wave is after clipping). This makes chords sound bad. If you take some bass out:     " target="_blank">http://www.geocities.com/SunsetStrip/Studio/2987/100p1k2.gif">     Then it sounds better with chords. BUT... it will sound "thinner". So you have to trade thickness for clarity on chords. A Fuzz Face is very thick sounding, but you're kind of limited to single note soloing unless you're after some serious noise.     I think the best way to get out of this trap is to distribute the harmonics generation along several stages. Instead of having a sibgle clipping stage that does all the distortion, try a lot of "almost clean" stages in series. This should help with the intermodulation without the need to cut a lot of bass. RG has talked about this idea several times. And if you think about it... that's more or less what's going on inside a tube amp
