Thanks for the demo -- I have just started researching this unit, and am interested to hear the 2600 filter as well.

@DJPeteJames thanks. i just opened it up and drew up the schematic for it a couple days ago. There's a lack of low end and proper square wave sounds cause they use a lot of dc blocking caps. as we all know, these act as high pass poles and can turn a nice square wave into a retarded looking sawtooth thing. their diode ladder is made of 2n5089 npn's that are diode connected and they've got an lm13600 as a vca in the feedback path for q control. if i get a mod to fix the bass, i'll post it...
