20 years ago I spent a lot of time building a moog like modular synth. The guy who's modules I built for it had done some work with Bob Moog and seemed like a good fit, but more modern. So it was cleaner, much more transparent and more stable. All these years later I'm not sure that is better! I have an old SH-101 which is cheap, noisy and dirty - I often prefer that sound for bass.
