The Slim Phatty is a monophonic analog synthesizer manufactured by Moog Music from 2011–2014.

The only other Moog synthesizers that can boast this capability are the Little Phatty, Minimoog Voyager, and the early Memorymoog+.

It also features two robust oscillators, diverse tuning controls, and the patented “Moog Ladder” filters.

Moog removed the keyboard, as well as the pitch and modulator wheels, and compacted the entire setup into a unit that is only seventeen inches wide.

For these reasons, many may find the control panel a little cluttered, although the use of smaller knobs and buttons helps alleviate this issue.
