Original vintage ARP Solus & Avatar synth monster!!! 4 VCOs, 4 filters, 2 LFOs, 4 envelopes, ring mod, sample & hold, 3 noise generators, you can filter the audio of either unit back through the filters of the other, or use as the input for the ring modulator, or trigger something, or smash something, or god knows what. With all of the routing & modulation possibilities of a semi modular 2600, (plus stereo master outputs. My fave is battling the oscillator synch with detuned oscillators on the other board. You will get lost in the nerd. If you have an hexaphonic arp guitar synth pickup, well....
Both units are in great condition, no issues. Enjoy!!!!!!
