For sale is an 1978 ARP Pro/DGX, the successor to the ARP Pro Soloist. This synthesizer has just been fully restored and serviced by Synthchaser, the west coast’s leading ARP specialist – recapped, new bushings, new LED sliders, new aftertouch sensor, fully functional, calibrated and sounding great. This keyboard is the sound of early Genesis through the Lamb Lies Down On Broadway. I’ve made a video to demonstrate the keyboard’s features and provide samples of the preset voices (which can be altered by the voltage controlled filter and the selectable aftertouch effects).
Video demonstrating this keyboard
Overall great condition for a nearly 40 year old synthesizer, with some cosmetic issues as visible in the photos (sticker residue on back, dented end on right side).
- Synthchaser Precision LED slider upgrade. All 4 of the old original sliders have been replaced with new, smooth, high precision LED illuminated sliders. The difference in the way these sliders feel and perform compared to the originals is a huge improvement.
- Synthchaser Capacitor Kit installed – All polarized capacitors in the entire synthesizer (not just the power supply) have been replaced to ensure stable operation for years to come.
- Synthchaser 4075 Filter Enhancement Kit installed – The Pro/DGX uses the same 4075 filter submodule found in the Odyssey, Quadra, and Omni. The filter has been recapped and enhanced to improve the cutoff frequency.
- New aftertouch sensor – The original aftertouch sensors are a common failure point and the aftertouch effects are what makes this synthesizer so expressive–we replaced the aftertouch sensor with a new long-lasting one to ensure the aftertouch will work for years to come.
- Action restoration – New key bushings installed, keys removed and washed, key contacts cleaned and adjusted
- Aftertouch and all aftertouch effects working: Volume, Wow, Growl (Growl switch is a bit touchy), Brilliance, Volume, Vibrato
- Oscilloscope Calibration – Fully calibrated to factory spec under measurement by oscilloscope
