MOTM

I am pondering an ARP 4072-type, 4-pole lowpass clone (with added VC
resonance). This was used in
the later "orange-faced" 2600s, and uses LM3900 Norton amplifiers. A ghastly
part designed to be
the world's cheapest quad op amp for use in Delco automotive electronics
(and used extensively in
Serge modules). However, it's that part that creates the 'bubbly, gurply,
reed' sound.

I have to admit, I'd also buy a few of these...
