MS-20

First of all, it only kind of sounds like an actual MS-20... but that isn't a problem, in my view. It's great on its own, in particular as an FX unit. I use the LPF as a wah effect on my guitar -- awesome, one of the best software wahs around. The filters in general are great, very good (if not actually spot-on) digital renditions of the old MS-20 filter sound. Love this plugin, but yeah, if you're looking for the authentic MS-20 sound, you may be a bit disappointed; appreciate it on its own merits, and it's a winner. (Edit: should also mention -- AWESOME, I mean truly, for bass sounds, especially if you follow them with a good tube saturation sim, Ferric TDS comes to mind among the free ones!)
