Vintage ARP 1613 & Mk II 1623 Sequencers w/ New Sliders

1613 via this eBay listing, also on Reverb

"The vintage ARP Sequencer is an exceptionally flexible analog step sequencer, offering independent control of two 16-step rows for complex patterns, modulation, and real-time performance tweaks. Renowned for its versatility, it can drive multiple synths, modulate parameters, or create evolving textures—making it a powerful centerpiece for any vintage or modular setup.

This is the real deal, a genuine vintage ARP sequencer, not a clone or remake! The sequencer is in very good physical condition and has just been serviced by ARP expert Synthchaser in October 2025. Work done included:

Synthchaser Precision slider upgrade. New, smooth, high precision Bourns sliders. The difference in the way these sliders feel and perform compared to the originals is a huge improvement.
Synthchaser replacement pushbutton switches - All new pushbutton switches -- the original switch caps are still installed so it looks the same from the outside.
Recapped all polarized capacitors - including power supply and all tantalum capacitors
New nuts and washers
Calibrated to factory spec

The ARP Sequencer has Tini-D jacks (like the ARP 2600 and other vintage ARP gear), which are slightly larger than 3.5mm patch cords. 3.5mm patch cords will still work, but for the best connection it's advised to use Tini-D patch cords."
