Minimoog Model D

The Minimoog Model D is the synthesizer that put the West Coast whine in your speakers. Launched in 1970 as the first portable, all-in-one synth, it became a funk bass machine for Parliament-Funkadelic’s Bernie Worrell, fed Roger Troutman’s talk box, and gave Dr. Dre the high, gliding lead that defined G-funk.

History

Before the Minimoog, synthesizers were room-sized modular systems patched together with cables. Moog put three oscillators, its famous ladder filter and a small keyboard in one box you could carry to a gig. The original ran until 1981. Moog reissued it in 2016 and again in 2022, and Behringer’s Model D clone brought the circuit to a budget price.

The sound

Stack the three oscillators and you get a huge, round bass. The 24 dB ladder filter gives it that warm, fat tone. The glide control slides one note into the next, and that is the key to the G-funk lead: a thin, high tone bending between pitches, often called the G-funk whistle.

G-funk and The Chronic

Dr. Dre wanted The Chronic (1992) to feel like a real Parliament-Funkadelic record, and keyboardist Colin Wolfe said he was thinking of Bernie Worrell when he played. Dre used a Minimoog to replay Leon Haywood’s melody on “Nuthin’ but a ‘G’ Thang,” and Moog bass and whiny leads run through Snoop Doggy Dogg’s Doggystyle (1993), including “Gin and Juice.” A wave of G-funk records chased that sound for the rest of the decade.

Buying one today

Original 1970s Model Ds are expensive and vary a lot in condition. Check that all three oscillators stay in tune once warmed up, every key triggers cleanly and the wooden case is intact. The Moog reissues are the straightforward route to the real thing; the Behringer Model D is the budget version.
