Erica Synths Black Hole DSP2 in very good condition. Fully functional, tested, sounds killer. Minor signs of use consistent with a studio rack — see photos, including the rear PCB.

The DSP2 packs 24 custom stereo effects (reverbs, delays, pitch shifting, distortion, modulation) into 16HP. Each effect has three parameters controllable by knob or CV, plus CV over effect selection, dry/wet, and sample rate — dial it from clean 48kHz down to crunchy lo-fi with the CRUSH control. No original box or ribbon cable — ships securely packed with plenty of padding. Standard Eurorack power cable is all you need.
