Octave CAT SRM Model 1853 SN B4046
Note: Auction links are affiliate links for which the site may be compensated.
via this eBay listing
"A bold, duophonic analog classic with a reputation for massive tone and underrated flexibility.
This is the Mk II version of the legendary Octave CAT — a U.S.-built synth from the mid-to-late 1970s that offers two VCOs with saw, square, and triangle waveforms (VCO 1 only), cross modulation, oscillator sync, and mixable waveforms. With duophonic capabilities and a famously powerful filter section, the CAT delivers deep bass, snarling leads, and complex drones with ease.
Key Features:
Two VCOs with independent modulation routing
Oscillator sync, cross-mod, and sub-octave options
VCF with audio-rate modulation and noise source
SRM (Series Revision Model) Mk II panel layout with white-only graphics
Bypass switch, modulation source selectors, and fine-tuning control
Serial number B4046
This unit is fully functional and sounds incredible. Cosmetically, it shows normal wear for its age, but everything works as intended.
An increasingly rare and highly regarded U.S.-made synth that stands tall next to the Minimoog, ARP Odyssey, and Pro-One — but with its own unique voice and vibe."

Bad Gear - OverPriced-1

"Welcome to Bad Gear, the show about the world’s most-hated audio tools. In light of recent events we are going to talk about OP-1 Field.
While other manufacturers either “pass on savings from process optimization” or relentlessly jack up prices once people are actually buying their music making toys, our favorite interior design company/copyright agency/nepo baby cult just flexed their monstrous marketing muscle and - did both at the same time.
