Arp Solus in very good condition. Normal wear and tear, but exceptionally clean for a unit that is 35 years old. I am the original purchaser of this unit. It was serviced within the last 9 months by a nationally recognized vintage synth tech. The unit has been updated to the last factory spec released for the Solus model. All functions are working at full factory spec, although the CV, Trig, and Gate I/O has not been tested by me personally. Sliders all working, although several can be somewhat stiff until they have been worked in for a bit. All keys respond as new. Like most analog synths it takes a few minutes to warm up. Much, if not all of the original documentation is included with the unit, operation manual, tablet to record patches, Arp users list, and list of Arp representatives in the US.
Specs: The Solus is a 2 VCO, monophonic analog synthesizer with a 3-octave, 37-note (C-C) keyboard. It, like most ARP synths, features mostly sliders instead of knobs. It was built into a flight-case, with all of its inputs and outputs on the inside of the case lid.
Both VCO’s feature a slider selecting variable waveforms from sawtooth to pulse, as well as a slider controlling pulse-width and the amount of pulse-width modulation. VCO2 is syncable to VCO1 and can be detuned. The pulse-width can be modulated by the LFO or the ADSR. The VCF (four-pole, lowpass filter) has controls for frequency, resonance, as well as three sliders controlling modulation amount from the keyboard, the LFO, and the ADSR. It also features a digital ring-modulator and a pitch-bend knob. The back panel features interfaces (in and out) for CV, Gate, and Trig. Also in the top panel is a footpedal input and External Audio input, as well as high and low outputs.
There is a small piece of reflective tape marking the correct output for the road crew. I thought it best not to remove it after all these years. You will not find a sweeter, more complete and original Solus than this unit. It’s a great unit but needs a new home with someone that has the time to play and appreciate it.” Click here to visit listing on eBay
