ADDAC System ADDAC712 Vintage Pre
The ADDAC712 Vintage Pre is a dual-channel discrete gain staging amplifier in the Eurorack format, part of ADDAC System's 700 Series. It's built around a discrete preamp board design from the 1970s - the kind found in "some legendary equipment," as the manufacturer puts it, though exactly which gear inspired it isn't documented. What caught ADDAC's attention was the character of its clipping and the saturation and distortion that come with it. Drive it gently for soft clipping or push it hard into fuzz-like saturation.
It's a compact 6HP module, 4 cm deep, drawing 40mA on both the +12V and -12V rails. ADDAC offered it as a factory-built module and as a full DIY kit, which synthCube also listed as a "Factory Kit." A manual exists and is referenced in period listings, but its contents aren't widely reproduced.
The record is thin. No gain range, frequency response, THD, or signal-to-noise figures were published in the sources that survive. No original production years or launch price are confirmed. A ModularGrid listing shows $189.73, but that's a single, uncorroborated data point. No user reviews or owner feedback have surfaced, and nothing is recorded about common issues or maintenance. What is known is that it's a two-channel discrete preamp module designed around the sound of its clipping, and that it sits alongside the related ADDAC714 Vintage Clip and ADDAC713 Stereo Discrete Mixer in ADDAC's lineup.
