TC Electronic M300

TC Electronic M300 is a compact and easy-to-use dual multi-effects processor that offers a wide range of effects and reverbs at an attractively affordable price. TC Electronic, known for their expertise in multi-effects processing and artificial reverberation, has designed the M300 to provide high-quality effects without compromising on usability. In this article, we will explore the features and capabilities of the M300, its user-friendly interface, and its suitability for different applications.


Digital multi-effects processors have evolved significantly since their inception in the late ’80s, with TC Electronic establishing themselves as leaders in the field. The M300 represents TC Electronic’s commitment to delivering quality effects and reverbs in a compact and easy-to-use package.

Mechanics & Interfaces

The TC M300 is housed in a shallow 1U rackmount box with a sleek black steel case and a silver-grey front panel adorned with knobs—a departure from the LCD displays and menu-driven interfaces common in many multi-effects units today. At the rear panel, the M300 features inputs and outputs capable of accommodating both balanced and unbalanced signals at various line levels. The unit also provides digital interfacing options through S/PDIF phono connectors.

Hands-on Control

TC Electronic has designed the M300 with a hands-on control interface consisting of knobs and switches, deviating from the traditional LCD displays and navigation buttons found in most multi-effects units. The absence of complex menus and the use of physical controls make the M300 highly intuitive and user-friendly, especially in live performance scenarios where quick parameter adjustments are crucial.

The Multi-effects Engine

The M300’s multi-effects engine offers a comprehensive selection of effects algorithms, including delays, phasers, tremolos, flangers, chorus, compression, de-essing, and more. Each algorithm can be easily selected using the large rotary switch. The two rotary controls beside it adjust various parameters specific to each effect, such as timing, feedback, modulation rate, and depth.

The Reverb Engine

In addition to the multi-effects engine, the M300 features a dedicated reverb engine with a diverse collection of algorithms. The rotary switch allows users to choose from concert halls, vocal rooms, cathedrals, drum rooms, ambience, spring reverbs, plates, and more. The accompanying rotary controls adjust parameters such as pre-delay, decay, and color, enabling precise control over the reverb characteristics.

Scrolling Through The Presets

The M300 provides a convenient preset management system for quick recall of user settings. With the press of a button and the use of up and down arrows, users can navigate through 99 user presets. The preset number is displayed on a two-digit seven-segment display, and small LEDs indicate any parameter deviations from the stored settings. The M300 also offers MIDI functionality, allowing users to control presets and parameters remotely. Attention: The unit doesn’t come with premade presets. I spent more than an hour trying to figure out how to activate the presets, resetting the unit multiple times.

The M300 In Action

The M300 excels in live performance scenarios, offering immediate control over every effect parameter. Its user-friendly interface enables on-the-fly adjustments without the need for complex menu navigation. For recording musicians and studio engineers, the M300’s simplicity and quick access to essential parameters outweigh the relatively fewer adjustable options. The unit provides high-quality effects and reverbs that can be easily tailored to suit different musical contexts.

TC Electronic M300 Price

The affordability of the M300 makes it an excellent investment for those seeking high-quality effects processing without breaking the bank. You can find used units on Reverb for about $100. I was lucky and got my unit for only 58€ on ebay.

TC M300 With Analog Synths

The TC Electronics M300 is an excellent companion for analog synthesizers that lack built-in effects. Analog synthesizers are prized for their unique and rich sound, but often require external effects to add depth and dimension to their output. The M300 fills this gap perfectly by offering a broad range of effects and reverbs that can enhance the sonic capabilities of analog synthesizers. Whether it’s adding lush reverbs, dynamic delays, swirling phasers, or vibrant choruses, the M300 allows users to explore endless sonic possibilities and elevate their analog synthesizer sounds to new heights. With its user-friendly interface and hands-on control, the M300 seamlessly integrates into the analog synthesizer setup, providing a powerful and versatile effects processing solution that brings out the best in these classic instruments.
