Review MOOG 123139 Used

The Moog 123-139, also known as the Moog 139 011, is a high-performance electro-mechanical low-pass filter designed for professional audio applications. This filter is a part of Moog's iconic Minimoog series, which has been a staple in the music industry for decades.

The Moog 123-139 is a 24dB per octave filter, which means it provides a steep roll-off in frequency response. It is a 12dB octave low-pass filter, meaning it allows low frequencies to pass through while attenuating high frequencies. The filter's cutoff frequency can be adjusted continuously from 20 Hz to 20 kHz, providing a wide range of tonal shaping capabilities.

This filter features a self-oscillating design, which means it can generate complex and rich harmonics when the resonance control is increased. The resonance control knob allows for adjustment from subtle self-oscillation to wild and aggressive resonances, making it a versatile tool for sound designers and electronic music producers.

The Moog 123-139 is constructed using Moog's renowned analog circuits, which provide warm and rich sound qualities that are unmatched by digital processing. The filter's input and output jacks are robust and can handle high current signals, making it suitable for use with synthesizers, drum machines, and audio processors.

The Moog 123-139 is housed in a rugged and durable steel enclosure, with a black powder-coated finish that provides protection against damage and corrosion. The filter's controls are laid out intuitively, making it easy to use and adjust on the fly.

Overall, the Moog 123-139 is a must-have tool for anyone working in professional audio applications who requires a high-quality and versatile low-pass filter. Its warm and rich analog sound, wide frequency range, and self-oscillating capabilities make it an essential component for sound design and electronic music production.

The Moog 123-139, also known as the Moog Sub 37, is a synthesizer that has gained popularity among musicians and producers for its analog sound and versatility. Here are some pros and cons of buying this synthesizer:

1. Analog Sound: The Moog Sub 37 uses analog circuitry to generate its sounds, which gives it a unique and rich tone that digital synthesizers may not be able to replicate.

2. Versatile: This synthesizer can produce a wide range of sounds, from deep basses to sharp leads, making it a great investment for producers and musicians in various genres.

3. Compact and Portable: The Sub 37 is relatively small and lightweight compared to other analog synthesizers, making it easier to transport and use in different settings.

4. MIDI Capable: This synth has MIDI capabilities, allowing it to be controlled by a computer or other MIDI devices, expanding its functionality.

5. Affordable: The Moog Sub 37 is priced lower than some of Moog's other synthesizers, making it a more accessible option for those on a budget.

1. Limited Polyphony: The Sub 37 only has one voice of polyphony, meaning that only one note can be played at a time without the others being affected.

2. No Arpeggiator: Some users may find the lack of an arpeggiator to be a limitation, as it can be a useful tool for creating complex melodies and rhythms.

3. No USB MIDI: The synth does not have a USB MIDI input, so it may require additional hardware to connect to a computer.

4. No Sequencer: The Sub 37 does not come with a built-in sequencer, which means that patterns must be programmed using an external device or manually.

The Moog Sub 37 offers a unique analog sound and versatility in a compact and portable package, making it an attractive option for producers and musicians looking to expand their sound palette. However, it may not be ideal for those who require polyphony, arpeggiator, USB MIDI, or a sequencer. Ultimately, the decision to buy the Moog Sub 37 depends on individual preferences and needs.

If you're looking for an affordable, versatile, and portable analog synthesizer with a rich and unique sound, the Moog Sub 37 is an excellent choice. However, if you require more features such as polyphony, arpeggiator, USB MIDI, or a sequencer, you may want to consider other options from Moog or other synthesizer manufacturers.
