Synthesizers dot com LFO Prototype Auction Benefits Bob Moog Foundation, internationally recognized creators of analog modular synthesizers, are auctioning a rare prototype of their Q167 LFO++ module, with proceeds to benefit the Bob Moog Foundation.  The 10-day auction runs from 1pm (PST) December 22 through 1PM (PST) December 30, 2015. It is being posted on eBay. This one-of-a-kind module, built and signed by master synth designer Roger Arrick, is fully functional, though differs slightly from the final production units.

The Q167 LFO++ is a pure analog module offering unique features including a precision LFO that operates into the audio range and tracks a 1v/octave keyboard or sequencer, and a wave shaping section that creates clean sine waves, anti-sine waves, curved sawtooth, gates, and more.

The built-in envelope generator provides control of the LFO’s speed and/or amplitude over time, with control over sustain TIME to produce sections of waveforms, bursts of gates, delayed vibrato, and more. The special configuration of the LFO++ makes it easy to control vibrato, tremolo and filter modulation with a wheel controller, keyboard pressure or a sequencer – great for controlling beat-count on individual sequencer steps.The prototype being auctioned is one of a kind, with a printed label front panel and a raw, hand-soldered circuit board with some components mounted in sockets. The unit can be used in any Moog-Unit format modular synthesizer with a power system. Face plate measurements are 8.75″ x 2.125″ x 2.25″ deep behind the panel. Requires: +15v,-15v,+5v.

Roger Arrick, founder of, explains, “I have been designing modular synthesizers for the past 20 years, and I usually keep all of my prototypes, so this is a rare offering. I have been deeply inspired by Bob Moog’s pioneering work, and it is an honor for me to give back by supporting the Bob Moog Foundation’s educational and historic preservation work through this auction.”
