"CA3130A and CA3130 are op amps that combine the advantage of both CMOS and bipolar transistors."

For example, I'm a big fan of TLC2262/2272, which are closer to an all-CMOS op amp. They are MUCH quieter than CMOS inverters, but the sound you get by overdriving them is significantly different. And they have the stuttering decay problem of most of the op amps.

See the internal schematics. But hey, if it sounds sweet it sounds sweet.
Several years ago I was trying various clipping stages (Mostly high gain): Diodes, jFET, Tube's (GROOVE tubes trio preamp, JCM800 preamp and so on), I found that there is nothing better than i.e. modified BSIAB 2 clipping ("Minibooster" stages). (http://www.youtube.com/watch?v=HKojnmT3CMg)
But when I heard reezafratzitz, now I can say that there is nothing better . Now I experimented with TS912, and found very similar clipping sound characteristics as 4069, but without extreme hiss noise.
